2024-12-20Version 3.70

- IMPORTANT: Windows 7, 8 and 8.1 support was dropped. Windows 10 is now the minimum required Windows version to use this toolchain.

- Removed the POSIX symlink compatibility layer from the compiler and linker source code and enforced automatic conversion to NTFS symlinks, hard links and junctions everywhere necessary.

- Removed the .xcframework bundle layout resolver logic from the compiler and linker source code and offloaded it to an external executable.

- Switched the LLVM/Clang compiler to the official, unpatched clang-17.0.6/Swift-6.0.3-RELEASE for Windows 10 to save (a lot of) maintenance work, offloading it to the LLVM team. At last!

- Switched the compiler cache to the official, unpatched ccache-4.10.2 to save more maintenance work (/me likes).

- Upgraded the Apple binary utilities to cctools-1010.6 with patches (visionOS, firmware and sepOS support - feedback welcome).

- Unity 6 IL2CPP support.

- Added a unique error tag to each error case for easier build script debugging.

- Miscellaneous fixes.

- NOTE: this release is the first one using yet another way for handling POSIX symlinks (and might be the last one before a major rewrite). Please do report all regressions in the support forum.

2024-08-10Version 3.65

- Upgraded LLVM/Clang compiler (Apple branch) to release tag "clang-16.0.0/swift-5.10.1-RELEASE".

- Improved the way the SDK build version is extracted by the Migration Assistant in case xcodebuild is not runnable.

2024-04-19Version 3.64

- Upgraded LLVM/Clang compiler (Apple branch) to release tag "clang-16.0.0/swift-5.10-RELEASE".

- Upgraded the Apple linker to ld64-951.9 with patches.

- Added support for statically-linked Xcode framework bundles (.xcframework) -- such as the ones used in the new Google Maps SDK.

- Fixed an elusive crash bug in the Apple ld64 linker which was caused by an improperly done platform-specific workaround.

- The Keychain UI can now create private keys and issue certificate signing requests using the EC (elliptic curves) algorithm (e.g. to obtain Apple Pay certificates).

2024-03-01Version 3.63

- The builder UI now proposes to automatically load a builder settings file if it's stored in the Xcode project root.

- The default save path of a builder settings file is now the Xcode project root. Feedback welcome on whether it's a time-saving idea or not.

- Improved the robustness of the master build script when evaluating the compiler flags for deciding whether creating a dSYM bundle is necessary.

2024-02-29Version 3.62

- Fixed an issue where a just built framework's headers (private and public) wouldn't be embedded in the output framework directory in the absence of a Swift module file.

- The build script now creates a local copy of the Win64 Unity IL2CPP build tools in the Xcode project directory (adding around 75 Mb) to make these projects portable and no longer depend on an existing Unity installation.

- For command-line power users who use the full iOS Build Environment to build Mac apps: added an 'icnstool' utility to create and extract macOS icon pack (.icns) files.

- For the same people: fixed quite some trailing issues in the 'makedmg' DMG file creation utility by refactoring a lot of the HFS+ code.

- For command-line power users only: the migration scripts are now able to migrate macOS, watchOS, tvOS and visionOS SDKs as well just by toggling a variable in the step 1 script.

2024-02-09Version 3.61

- Upgraded the Apple binary utilities to cctools-1009.2 with patches (visionOS, firmware and sepOS support - feedback welcome).

- Upgraded the Apple linker to ld64-907 with patches (ObjC msgSend stub prototypes, visionOS, firmware and sepOS support - feedback welcome).

- Upgraded crypto library used in code signing to LibreSSL-3.8.2 + PKCS#11 CryptoKI bindings to be on the safe side when the CA/B requirements for code signing security apply to the Apple store (see https://cabforum.org/uploads/Baseline-Requirements-for-the-Issuance-and-Management-of-Code-Signing.v2.8.pdf).

- The latter change adds support for storing the private key used in code signing to be stored on a hardware security module (HSM) or a USB security token.

- Fixed a problem causing apps using il2cpp created by recent Unity versions to be rejected by Apple because of erroneous inclusion of Swift arm64 libraries for the wrong platform.

- The upload tool now creates an "upload.log" file in the same directory as the .ipa file that's being uploaded to App Store Connect to help with upload problems.

- Fixed an issue with the CocoaPods daemon refusing to start on some versions of Windows 10 an 11 due to a change in the "chcp" tool output by Microsoft.

- Fixed an issue in the POSIX compatibility layer causing failures in various tools when trying to map large input files (larger than 2^31 bytes).

- Added the ability to set build numbers in more format than X.Y.Z in the UI: 'X' and 'X.Y' are also supported and will no longer append trailing '.0' and '.0.0's.

- Better guess at when to use the compiler-supplied Swift shims header files instead of the SDK-supplied ones (if any) at SDK migration time.

- Removed third-party curl utility, scripted downloads are now made by powershell's integrated WebClient.

- Added the ability for ccache to store its temporary directory on a network share (though not recommended for performance reasons).

- New private keys for code signature are now 4096-bit by default.

2023-11-08Version 3.60.2

- Fixed a regression in 3.60.1 affecting Xcode projects using Unity-generated il2cpp code that could no longer be built. My apologies.

- Fixed the inactivity watchdog of the new CocoaPods daemon.

- Fixed truncated build log problem by rewriting the tee utility.

2023-11-06Version 3.60.1

- Updated CocoaPods daemon to CocoaPods 1.14.2 over Ruby 3.2 in a new VM (watch out, 3 Gb RAM minimum is necessary now).

- Added a "sw_vers" utility to the CocoaPods daemon for the Pods that require one.

- Fixed missing symbolic links in the iOS SDK during migration.

- Blocked (in the UI) the ability to build 32-bit (armv7) variants of a project when either the installed SDK or the project itself don't support it.

2023-11-04Version 3.60

- This is an intermediary release: I haven't had enough time to finish all the improvements I planned for this version.

- Upgraded LLVM/Clang compiler (Apple branch) to release tag "clang-16.0.0/swift-5.9.1-RELEASE".

- Fixed an issue with the detection of the Unity IL2CPP compiler when looking at the default Unity install path.

- Fixed an Apple QA problem with the iOS 17 SDK where libxml would have two colliding modulemap files, preventing regeneration of compiler modules.

- Fixed a false positive in the dependency checker tool for framework binaries referenced by their canonical path (.framework/Versions/A/name -> .framework/name).

- Fixed an error in the realpath() implementation of the symlink emulation code that could cause a bad file path resolution.

- Fixed an error in the I/O code where files larger than 1 Gb could not be written in one pass (where is it documented that 0x40000000 is the largest writtable block size on Win32??)

- Worked around a problem where the Unity il2cpp compiler driver couldn't find GameAssembly source files accessed by relative paths.

- POSTPONED TO 3.60.1: Updated CocoaPods daemon to CocoaPods 1.14.2

- POSTPONED TO 3.60.1: Added a "sw_vers" utility to the CocoaPods daemon for the Pods that require one.

2023-07-31Version 3.59

- Upgraded LLVM/Clang compiler (Apple branch) to release tag "clang-15.0.0/swift-5.8.1-RELEASE".

- Fixed an issue in the .ipa file creation tool (makeipa.exe) where empty directories wouldn't be represented in the archive.

- Fixed an issue that prevented the remote debug console from being compiled properly with some SDKs.

- All executables are now signed to avoid false positives with virus scanners that flag unsigned executables as dangerous.

2023-06-30Version 3.58

- Fixed a potential crash in scp.exe (used by CocoaPods) by moving some allocations to the heap.

- Updated CocoaPods daemon to CocoaPods 1.12.1.

- Proper integration of Swift API notes within the platform-specific SDK (please migrate your iOS SDK again).

- pbxprojparse -sources now outputs Swift files first so that mixed sources modules can be built correctly (in a near future).

- The code signer now destroys the "com.apple.security.app-sandbox" entitlement if it's not signing a macOS app (as Xcode does).

- Increased tolerance in the LLVM linker for duplicated symbols when both source locations are within archives to mimic the Apple linker behaviour.

2023-05-26Version 3.57

- Added a dedicated dialog box to easily edit extra compiler and linker flags.

- Looks like you're interested in reading the changelog. Please read this one til the end.

- LLVM modules cache path moved from Toolchain to SDK directory (because these modules are specific to a certain SDK).

- Compiler cache (ccache) path moved to SDK directory (same rationale).

- LLVM modules are now enabled by default.

- Added the missing iOS glue to the Dispatch Swift framework to be able to build Swift code for iOS that uses threads.

- The Swift compiler is invoked in -frontend mode (as Xcode does) and not in driver mode (as Apple recommends).

- Added a -visibility flag to pbxprojparse to use with -headers so as to specify the desired visibility.

- Proper handling of header visibilities (private/public/project) when constructing LLVM modules.

- Improved waitfor utility for correctly watching over multiple instances of multiple compiler types in driver and frontend modes in multithreaded mode.

- One last thing. The toolchain is now able to build Swift code. Please report any issues to the support forum.
