# Changelog

Changes to `icrate` will be documented in this file.

This previously existed as a separate crate `objc2_foundation`, later it was
integrated into `objc2::foundation`, and later again split out - hence the
confusing versioning.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

## icrate Unreleased - YYYY-MM-DD


## icrate 0.1.2 - 2023-04-18

## Fixed
* Fixed "multiple applicable items in scope" error when upgrading `objc2` to `v0.5.1`.


## icrate 0.1.1 - 2023-04-17

### Deprecated
* Deprecated the `icrate` crate, it has been split into multiple smaller crates.


## icrate 0.1.0 - 2023-12-23

### Added
* Added `MainThreadMarker` `From` implementation for `MainThreadOnly` types.
* Added `Send` and `Sync` implementations for a bunch more types (same as the
  ones Swift marks as `@Sendable`).
* Made some common methods in `AppKit` safe.
* Added missing `NSCopying` and `NSMutableCopying` zone methods.
* Added `Eq` and `Ord` implementations for `NSNumber`, since its
  handling of floating point values allows it.

  `NS[Mutable]Dictionary::from_slice`.
* Added `NSMutableDictionary::insert` and `NSMutableSet::insert` which can
  be more efficient than the previous insertion methods.

### Changed
* Updated SDK from Xcode 14.2 to 15.0.1.

  Breaking changes are noted elsewhere in this changelog entry.
* Moved the `ns_string!` macro to `icrate::Foundation::ns_string`. The old
  location in the crate root is deprecated.
* **BREAKING**: The following two methods on
  `MTLAccelerationStructureCommandEncoder` now take a nullable scratch buffer:
  - `refitAccelerationStructure_descriptor_destination_scratchBuffer_scratchBufferOffset`
  - `refitAccelerationStructure_descriptor_destination_scratchBuffer_scratchBufferOffset_options`
* **BREAKING**: Marked UI-related classes as `MainThreadOnly`, and UI-related
  protocols as `IsMainThreadOnly`.

  This means that they can now only be constructed, retrieved and used on the
  main thread, meaning you usually have to aquire a `MainThreadMarker` first.

  ```rust
  // Before
  let app = unsafe { NSApplication::sharedApplication() };
  let view = unsafe { NSView::initWithFrame(NSView::alloc(), frame) };
  // Do something with `app` and `view`

  // After
  let mtm = MainThreadMarker::new().unwrap();
  let app = unsafe { NSApplication::sharedApplication(mtm) };
  let view = unsafe { NSView::initWithFrame(mtm.alloc(), frame) };
  // Do something with `app` and `view`
  ```
* **BREAKING**: Changed the `NSApp` static to be a function taking `MainThreadMarker`.
* **BREAKING**: Renamed `NS[Mutable]Dictionary::from_keys_and_objects` to
  `NS[Mutable]Dictionary::from_vec`.
* **BREAKING**: Renamed `NSMutableDictionary::insert` and
  `NSMutableSet::insert` to `insert_id`.
* **BREAKING**: `CWWiFiClient::interfaceNames` has been renamed to `CWWiFiClient::interfaceNames_class`.
* **BREAKING**: Updated `objc2` to `v0.5.0`.
* **BREAKING**: Updated `block2` to `v0.4.0`.

### Removed
* **BREAKING**: Removed the `MainThreadMarker` argument from the closure
  passed to `MainThreadBound::get_on_main`.
* **BREAKING**: Removed `Foundation::CopyHelper` since it is superseded by
  `objc2::mutability::CounterpartOrSelf`.
* **BREAKING**: Removed the following APIs, as they are no longer available in macOS 14 / iOS 17:
  - `NSFileProviderDomain::volumeUUID`
  - `CLBeaconIdentityConstraint::UUID`
  - `CLBeaconIdentityConstraint::major`
  - `CLBeaconIdentityConstraint::minor`
  - `ASIdentifierManager::clearAdvertisingIdentifier`
* Removed private `MetricKit::_MXSignpostMetricsSnapshot` function.

### Fixed
* **BREAKING**: Added `Eq + Hash` requirement on most `NSDictionary` and
  `NSSet` methods, thereby making sure that the types are actually correct
  to use in such hashing collections.
* **BREAKING**: Added `HasStableHash` requirement on `NSDictionary` and
  `NSSet` creation methods, fixing a long-standing soundess issue.
* Fixed the protocol names of `NSAccessibilityElementProtocol`,
  `NSTextAttachmentCellProtocol` and `NSFileProviderItemProtocol`.
* **BREAKING**: Generic types no longer strictly require `Message` (although
  most of their trait implementations still require that).
* **BREAKING**: Removed a workaround that made the `NSCopying` and
  `NSMutableCopying` protocols not act as regular protocols (many methods used
  `AnyObject` instead of the correct `ProtocolObject<dyn NSCopying>`).
* Update the minimum deployment target, which adds a few missing protocol
  implementations and methods for `NSPopover` and `NSLayoutAnchor`.
* **BREAKING**: `CKSystemSharingUIObserver` and `CKLocationSortDescriptor` are no longer marked thread safe.
* **BREAKING**: `NSColor::ignoresAlpha` now requires a main thread marker.


## icrate 0.0.4 - 2023-07-31

### Changed
* **BREAKING**: Updated `block2` to `v0.3.0`.

### Fixed
* Documentation on docs.rs.


## icrate 0.0.3 - 2023-06-20

### Added
* Added the following frameworks:
  - `HealthKit`
  - `MediaPlayer`
  - `MetricKit`
  - `PhotoKit`
* Added `NSCopying` and `NSMutableCopying` implementations for the classes
  that implement those protocols.
* Added the following methods:
  - `NSArray::get_retained`
  - `NSArray::first_retained`
  - `NSArray::last_retained`
  - `NSSet::get_retained`
  - `NSSet::to_vec`
  - `NSSet::to_vec_retained`
  - `NSDictionary::get_retained`
  - `NSDictionary::keys_retained`
  - `NSDictionary::values_retained`
* Added `MainThreadMarker::alloc` for allocating objects that need to be so on
  the main thread.
* Added automatically generated `new`/`init` methods for all types.
* Added `FromIterator` impls for various collection types.

### Changed
* **BREAKING**: Renamed the `from_slice` method on `NSArray`, `NSSet`,
  `NSMutableArray` and `NSMutableSet` to `from_id_slice`, and provided a new
  `from_slice` method that takes `&[&T]` instead.
* **BREAKING**: Changed `NSMutableArray::replace` to return an `Result` in
  case the index was out of bounds.
* **BREAKING**: Changed `NSMutableArray::remove` to return an `Option` in case
  the index was out of bounds.
* **BREAKING**: Removed ownership parameter from generic types, since the
  ownership/mutability information is now stored in `ClassType::Mutability`.
* **BREAKING**: Renamed `NSMutableCopying::mutable_copy` to `::mutableCopy`.
* **BREAKING**: The default value for `NSUUID` was changed from a nil UUID to
  a new random UUID.
* **BREAKING**: Changed how iteration works.

  Instead of the single `NSFastEnumerator`, we now have concrete types
  `array::Iter`, `array::IterMut`, `array::IterRetained` and
  `array::IntoIter`, which allows iterating over `NSArray` in different ways.

  Combined with proper `IntoIterator` implementations for collection types,
  you can now do:
  ```rust
  let mut array: Id<NSMutableArray<T>> = ...;

  for item in &array {
      // item: &T
  }

  // If T: IsMutable
  for item in &mut array {
      // item: &mut T
  }

  // If T: IsIdCloneable
  for item in array.iter_retained() {
      // item: Id<T>
  }

  for item in array {
      // item: Id<T>
  }
  ```

  (similar functionality exist for `NSSet` and `NSDictionary`).
* **BREAKING**: Renamed `NSDictionary` methods:
  - `keys` -> `keys_vec`.
  - `values` -> `values_vec`.
  - `values_mut` -> `values_vec_mut`.
  - `keys_and_objects` -> `to_vecs`.
  - `iter_keys` -> `keys`.
  - `iter_values` -> `values`.
* **BREAKING**: `NSDictionary::keys_retained` and
  `NSDictionary::values_retained` now return an iterator instead.
* **BREAKING**: Updated `objc2` to `v0.4.0`.
* **BREAKING**: Updated `block2` to `v0.2.0`.

### Removed
* **BREAKING**: Removed various redundant `NSProxy` methods.
* **BREAKING**: Removed `NSArray::to_shared_vec` and `NSArray::into_vec`, use
  `NSArray::to_vec` or `NSArray::to_vec_retained` instead.
* **BREAKING**: Removed associated types from `NSCopying` and
  `NSMutableCopying`, that information is now specified in
  `ClassType::Mutability` instead.
* **BREAKING**: Removed a few `init` methods on subclasses that were declared
  on categories on their superclass. These should be re-added at some point.

### Fixed
* Soundness issues with enumeration / iteration over collection types.

* Updated the SDK version from XCode `14.0.1` to `14.2`.
  - See differences [here](https://sdk.news/macOS-13.0/).
* Added `Foundation::MainThreadBound` helper struct for things that are only
  accesible from the main thread.
* Added `#[deprecated]` annotations to the autogenerated output.
* Added disambiguation for duplicated methods (e.g. `NSThread::threadPriority`
  vs. `NSThread::threadPriority_class`).
* Properly implemented protocols for defined classes.

### Changed
* Cfg-gated static `ns_string!` functionality behind the
  `unstable-static-nsstring` cargo feature.
* Autogenerated method parameters are now in snake-case, for better IDE
  support.
* **BREAKING**: Cfg-gate all classes, and everything that references said
  classes.

  This means that to use e.g. `Foundation::NSThread::name`, you have to enable
  the `Foundation_NSThread` and `Foundation_NSString` cargo features.
* **BREAKING**: Updated `objc2` to `v0.3.0-beta.5`.
* **BREAKING**: Updated `block2` to `v0.2.0-alpha.8`.

### Removed
* **BREAKING**: The optional `uuid` integration, since one might want to use
  `icrate` internally in that crate in the future, and that would break.
* **BREAKING**: Removed `NSNib::instantiateWithOwner_topLevelObjects`,
  `NSBundle::loadNibNamed_owner_topLevelObjects` and `NSFreeMapTable` since
  they had weird memory management.

### Fixed
* Ensure we never hit a memory management issue again.
* **BREAKING**: Fixed a few `*mut` pointers that should've been `*const`.
* **BREAKING**: Fixed a few generic ownership parameters that defaulted to
  `Shared`.
* Removed a few instances of `TodoProtocols`.
* Fixed type-encoding of a few `struct`s.
* Fixed `NSProxy` trait methods.
* **BREAKING**: Fixed type in methods that worked with out-parameters.

    - `main` -> `mainThread`
    - `is_main` -> `isMainThread`

    - `process_info` -> `processInfo`
* **BREAKING**: Make `NSComparisonResult` work like all other enums.
* **BREAKING**: Changed `NSDictionary` to be `Shared` by default.
* **BREAKING** (TEMPORARY): Renamed `NSEnumerator`, `NSFastEnumeration` and
  `NSFastEnumerator` until the story around them are properly figured out.
* **BREAKING**: Make `NSArray::objects_in_range` return an `Option` (it was
  unsound before).

### Fixed
* Fixed `NSZone` not specifying a `#[repr(...)]`.


## objc2::foundation 0.3.0-beta.3 - 2022-09-01

### Added
* Added `NSSet`.
* Added `NSMutableSet`.
* Added `NSMutableDictionary`.
* Added `NSNotFound`.
* Added `NSBundle`.
* Added `NSTimeInterval`.
* Added `NSString::len_utf16` and `NSAttributedString::len_utf16`.
* Added `NSString::concat` and `NSString::join_path`.
* Added `CGSize`, `CGPoint` and `CGRect` (aliases to equivalent `NS`-types
  that helps readability).

### Changed
* **BREAKING**: `NSSize::new` no longer requires it's arguments to be
  non-negative. Use `NSSize::abs` or `NSRect::standardize` if the API you're
  binding to requires a non-negative size.


## objc2::foundation 0.3.0-beta.2 - 2022-08-28

### Added
* Added `NSNumber`.
* Added `NSError`.
* Implement `UnwindSafe` and `RefUnwindSafe` for all objects.
* Implemented `IntoIterator` for references to `NSArray`, `NSMutableArray`,
  `NSData` and `NSMutableData`.
* Implemented `Extend` for `NSMutableArray`.
* Add extra `Extend<&u8>` impl for `NSMutableData`.
* Added function `NSValue::contains_encoding` for determining if the encoding
  of the `NSValue` matches the encoding of the given type.
* Added functions `get_range`, `get_point`, `get_size` and `get_rect` to
  `NSValue` to help safely returning various types it will commonly contain.
* `NSArray` and `NSMutableArray` now have sensible defaults for the ownership
  of the objects they contain.

### Changed
* **BREAKING**: Moved from external crate `objc2_foundation` into
  `objc2::foundation`.
* **BREAKING**: Made `NSValue` not generic any more. While we loose some
  type-safety from this, it makes `NSValue` much more useful in the real
  world!
* **BREAKING**: Made `NSArray::new` generic over ownership.
* **BREAKING**: Made `NSObject::is_kind_of` take a generic `T: ClassType`
  instead of a `runtime::Class`.

### Fixed
* Made `Debug` impls for all objects print something useful.

### Removed
* `NSObject::hash_code`, `NSObject::is_equal` and `NSObject::description` in
  favour of having the trait implementations `Hash`, `PartiqalEq` and `Debug`.


## objc2-foundation 0.2.0-alpha.6 - 2022-07-19

### Added
* Added `MainThreadMarker` to help with designing APIs where a method is only
  safe to call on the main thread.
* Added `NSException` object.
* Added `extern_class!` macro to help with defining interfaces to classes.
  Further changelog for this can be found in `CHANGELOG.md`.
* Added `declare_class!` macro to help with declaring custom classes.
  Further changelog for this can be found in `CHANGELOG.md`.
* Expose the `objc2` version that this uses in the crate root.
* Added `NSZone`.

### Changed
* Changed a few `Debug` impls.


## objc2-foundation 0.2.0-alpha.5 - 2022-06-13

### Added
* Objects now `Deref` to their superclasses. E.g. `NSMutableArray` derefs to
  `NSArray`, which derefs to `NSObject`, which derefs to `Object`.

  This allows more ergonomic usage.
* Implement `PartialOrd` and `Ord` for `NSString` and `NSRange`.
* Added `NSString::has_prefix` and `NSString::has_suffix`.
* Added `NSRange` methods `new`, `is_empty`, `contains` and `end`.
* Added `NSThread` object.
* Added `is_multi_threaded` and `is_main_thread` helper functions.
* Added `NSProcessInfo` object.
* Added `NSMutableData` methods `from_data`, `with_capacity` and `push`.
* Added `io::Write` and `iter::Extend` implementation for `NSMutableData`.
* Added `NSUUID` object.
* Added `NSMutableString` object.
* Added basic `NSAttributedString` object.
* Added basic `NSMutableAttributedString` object.
* Added `NSInteger` and `NSUInteger` (type aliases to `isize` and `usize`).
* Added `CGFloat`.
* Added `NSPoint`.
* Added `NSSize`.
* Added `NSRect`.
* Implement `Borrow` and `BorrowMut` for all objects.
* Implement `ToOwned` for copyable types.

### Changed
* **BREAKING**: Removed the following helper traits in favor of inherent
  methods on the objects themselves:
  - `INSMutableArray`
  - `INSArray`
  - `INSMutableData`
  - `INSData`
  - `INSDictionary`
  - `INSString`
  - `INSValue`
  - `INSObject`

  This changed because objects now deref to their superclasses.
* **BREAKING**: Relaxed a lot of bounds from `INSObject` to `Message`. At some
  point in the future a new trait will be introduced which remedies this
  change.
* **BREAKING**: Removed the `I` prefix from:
  - `INSCopying` (now `NSCopying`)
  - `INSMutableCopying` (now `NSMutableCopying`)
  - `INSFastEnumeration` (now `NSFastEnumeration`)
* **BREAKING**: Renamed `NSMutableData::append` to `extend_from_slice`.


## 0.2.0-alpha.4 - 2022-01-03

### Added
* Implement `PartialOrd` and `Ord` for `NSComparisonResult` and `NSValue`.
* Implement `fmt::Display` for `NSValue`.
* Implement `DefaultId` for relevant objects.
* Implement `AsRef` and `Index` for `NSData` and `NSMutableData`.
* Implement `AsMut` and `IndexMut` for `NSMutableData`.

### Changed
* **BREAKING**: Renamed `INSFastEnumeration::enumerator` to
  `INSFastEnumeration::iter_fast`.

### Removed
* **BREAKING**: Removed `Deref` and `DerefMut` from `NSData` and
  `NSMutableData`, since these invoke a non-trivial amount of code, and could
  lead to hard-to-diagnose performance issues.


## objc2-foundation 0.2.0-alpha.3 - 2021-12-22

### Added
* **BREAKING**: Added associated `Ownership` type to `NSCopying`.
* **BREAKING**: Added associated `Ownership` type to `INSData`.
* **BREAKING**: Added associated `Ownership` type to `INSArray`.
* Added common trait impls (`PartialEq`, `Eq`, `Hash` and `Debug`) to
  `NSValue`, `NSDictionary`, `NSArray` and `NSMutableArray`.

### Changed
* **BREAKING**: Made some creation methods a bit less generic (e.g.
  `INSDictionary::from_keys_and_objects` now always returns `Id<_, Shared>`).
* Relax bounds on generic `INSObject` impls.

### Removed
* **BREAKING**: Removed associated `Ownership` type from `INSObject`; instead,
  it is present on the types that actually need it (for example `NSCopying`).
* **BREAKING**: Removed `Sized` bound on `INSObject`.

### Fixed
* Soundness issue with `NSValue`, `NSDictionary`, `NSArray` and
  `NSMutableArray` not specifying a `#[repr(...)]`.
* **BREAKING**: `NSObject` is no longer `Send` and `Sync` (because its
  subclasses may not be).


## objc2-foundation 0.2.0-alpha.2 - 2021-11-22

### Added
* **BREAKING**: Added associated `Ownership` type to `INSObject` to specify
  whether the type can be mutated or not. `NSString` is a prime example of a
  type that you may never get a `Owned/&mut` reference to, since it is very
  easy to create two `NSString`s with the same underlying allocation.
* Added helper `is_empty` methods.
* Added `INSArray::first_mut` and `INSArray::last_mut`.

### Changed
* **BREAKING**: Renamed a lot of methods to better match Rusts naming scheme:
  - `INSArray`
    - `count` -> `len`
    - `object_at` -> `get`
    - `mut_object_at` -> `get_mut`
    - `shared_object_at` -> `get_retained`
    - `first_object` -> `first`
    - `last_object` -> `last`
    - `object_enumerator` -> `iter`
  - `INSMutableArray`
    - `add_object` -> `push`
    - `insert_object_at` -> `insert`
    - `replace_object_at` -> `replace`
    - `remove_object_at` -> `remove`
    - `remove_last_object` -> `pop`
    - `remove_all_objects` -> `clear`
  - `INSDictionary`
    - `count` -> `len`
    - `object_for` -> `get`
    - `key_enumerator` -> `iter_keys`
    - `object_enumerator` -> `iter_values`
  - `INSValue`
    - `value` -> `get`
    - `from_value` -> `new`
  - `NSComparisonResult`
    - `from_ordering` -> `from`
    - `as_ordering` -> `into`
  - `NSRange`
    - `from_range` -> `from`
    - `as_range` -> `into`
* Use `SliceId` for better performance when creating arrays and dictionaries.

### Removed
* **BREAKING**: Removed the `object_struct!` macro. It may be re-added in
  another form in the future.
* **BREAKING**: Removed `NSMutableSharedArray<T>` and `NSSharedArray<T>` type
  aliases. Use `NSMutableArray<T, Shared>` and `NSArray<T, Shared>` instead.
* **BREAKING**: Removed `Any / 'static` bound on `INSObject`. This allows
  implementing it for objects that contain lifetimes from the outer scope.

### Fixed
* **BREAKING**: Marked `INS...` traits as `unsafe` to implement.
* **BREAKING**: Removed `new` method from `INSObject` since some classes don't
  want this called. It has been re-added to other `INS...` traits on a case by
  case basis (in particular not `NSValue`).
* **BREAKING**: `INSString::as_str` now takes an a reference to
  `objc2::rc::AutoreleasePool`. This ensure that the returned `&str` is only
  used while the current autorelease pool is valid.
* Fixed `NSData::from_vec` on GNUStep.


## objc2-foundation 0.2.0-alpha.1 - 2021-10-28

### Added
* Implement new `RefEncode` trait for objects.
* Implement `Encode` for `NSComparisonResult` and `NSFastEnumerationState`.
* Implement `RefEncode` for objects and `NSFastEnumerationState`.

### Changed
* **BREAKING**: Uses `Id` from `objc2::rc` module instead of `objc_id` crate.
* **BREAKING**: `INSValue::encoding` now returns `&str` instead of `Encoding`.

### Fixed
* Use proper `#[repr(C)]` structs to represent Objective-C objects.
* `INSString::from_str` on GNUStep (`UTF8_ENCODING` was the wrong type).


## objc2-foundation 0.2.0-alpha.0 - 2021-08-29

Note: This is the version that is, as of this writing, available on the
`master` branch in the original `objc-foundation` project.

### Added
* Implement `Display` for `NSString`.
* Make `INSObject::class` faster using the `objc::class!` macro.

### Changed
* **BREAKING**: Forked the project, the crate name is now `objc2-foundation`.

### Fixed
* Fixed types in various calls to `objc::msg_send!` for better verification.


## objc-foundation [0.1.1] - 2016-06-19

### Removed
* `libc` dependency.


## objc-foundation [0.0.3] - 2015-11-07

### Added
