There were no changes outside of the CMake configuration.

What's Changed

  • Install the Foundation toolchain module during the static swift build by @jmschonfeld in #391

This patch release resolves issues uncovered since version 1.1.0 was published.

What's Changed

  • This version fixes a bogus assertion in Deque that can cause incorrect runtime traps in debug builds. (#381)
  • The unstable module _CollectionsUtilities was renamed to InternalCollectionsUtilities to work around an issue in shipping versions of Xcode. This renaming is not intended to make this module public -- it remains an unstable implementation detail. (#364)

Many thanks to our contributors for their work!

This feature release adds a number of new data structure implementations, along with minor changes to existing constructs.

New Data Structures

  • Heap implements a min-max heap, backed by a native array. (Contributed by @AquaGeek)
  • BitSet and BitArray are two alternate representations of a bitmap type, backed by dynamically allocated storage. (Contributed by @MahanazAtiqullah)
  • TreeSet and TreeDictionary are hashed collections implementing Compressed Hash-Array Mapped Prefix Trees (CHAMP). They provide similar API as Set/Dictionary in the Standard Library, but as persistent data structures, supporting incremental mutations of shared instances and efficient structural diffing. (Contributed by @msteindorfer)

Other Changes

  • This version of the package can only be built using Swift 5.7.2 or later.
  • New methods: the OrderedSet.isEqualSet family of functions provide a way to test that two containers contain the same members, ignoring the order of elements. (#183, #234)
  • New method: OrderedSet.filter implements a version of the standard filter operation that returns an OrderedSet instead of an Array. (#159)
  • debugDescription implementations have been updated to follow Swift best practice. (These are called by container types like Array to print their elements, so they work best when they're succinct variants of description that are suitable for embedding in structured output: specifically, they must not produce unpaired delimiter characters ([/], (/), {/}, </> etc), raw top level commas, semicolons, colons, unquoted strings etc. debugDescription should not needlessly print type names etc.)

Swift Collections 1.0.3

This release resolves issues uncovered since 1.0.2 was tagged. The fixes improve performance of some operations, resolve compile-time issues and update documentation. This release contains no observable behavioral changes.

Changes

  • [Clutter] When opened in Xcode, the package no longer adds spurious schemes to dependent projects. (#155)

Fixes

  • [Build-time issue] Code that is calling OrderedDictionary's uniquing/unique/grouping initializers and merge operations no longer gets flagged as ambiguous in certain cases involving type inference. (#125, #139)
  • [Build-time issue] The package no longer fails to build when library evolution is enabled. (#157) (Note: this configuration remains unsupported. This package does not provide any guarantees about ABI stability.)
  • [Performance] In-place mutations of collection contents no longer result in unnecessary heap allocations. (#164)
  • [Performance] On Swift 5.6 and better, some operations in the OrderedCollections module now make use of the stdlib's temporary allocation facility. (#160)
  • [Docs] Documentation was updated to clarify behavior of the filter and merge methods of OrderedDictionary. (#145)

Pull requests

  • #140 [OrderedDictionary] Fix type inference issue with OrderedDictionary.init(grouping:by:) (by @lorentey)
  • #153 [OrderedDictionary][doc] Update docs for merge/filter operations (by @lorentey)

Swift Collections 1.0.2

This release resolves issues uncovered since 1.0.1 was tagged, including a high severity crash in OrderedSet and OrderedDictionary. Upgrading is recommended for all clients.

Fixes

  • Fixed a value semantic violation in OrderedSet and OrderedDictionary that could result in some mutation methods corrupting shared copies of the same value, leading to subsequent crashes. (Issue #104)
  • Deque.append(contentsOf:) now uses an exponential storage resizing strategy, as expected. Calling it in a loop no longer results in O(n) reallocations. (Issue #113)

Pull requests

  • #113 [Deque] append(contentsOf:): Use exponential capacity reservation (by @lorentey)
  • #123 [OrderedSet] Add missing uniqueness check (by @lorentey)
  • #126 [Utils] run-full-tests.sh: Keep going after a failure (by @lorentey)
  • #128 [Utils] run-full-tests.sh: Add support for testing on Swift 5.3 without manual editing (by @lorentey)
