ZIP Foundation is a cross-platform Swift library for creating and manipulating ZIP archives, supporting macOS, iOS, Linux, and other platforms. It provides capabilities for reading, writing, and modifying ZIP files, including support for ZIP64 archives and in-memory operations. The library handles file attributes, error conditions, and progress reporting, with comprehensive test coverage and privacy manifest compliance.

The project now includes a standard Xcode workspace structure, adding the workspace data file and the IDE workspace checks plist. This ensures proper workspace setup and suppresses the 32-bit warning in the IDE.

ZIPFoundation now includes a PrivacyInfo.xcprivacy resource file to comply with Apple's privacy requirements. The manifest declares that the library accesses the NSPrivacyAccessedAPICategoryFileTimestamp API (reason code 0A2A.1) and confirms that no data is tracked or collected.

The project now includes a shared Xcode scheme (ZIPFoundation.xcscheme) that configures test runs to always execute in Release mode and enables code coverage generation. This ensures that developers and CI systems running tests via this scheme get consistent, optimized build behavior and coverage reports, rather than relying on default Debug-mode test configurations.

The CZLib source files have been updated to ensure correct compilation on Windows. A new module map and shim header replace previous imports with standard includes to avoid MSVC parsing errors, and explicit macros (\_LARGEFILE64\_SOURCE, \_FILE\_OFFSET\_BITS, \_LFS64\_LARGEFILE) are defined to enable 64-bit file offset support required by zlib on this platform.

This release adds support for file modification date attributes and code page 437 string decoding for paths on non-Darwin platforms. It fixes a resource leak in Archive.makeBackingConfiguration, a memory leak in Data.readChunk, and a memory alignment crash in debug mode. The library also improves error handling in the MemoryFile type and String to Data conversion, and updates README examples to use non-deprecated APIs.

The library's internal structure has been reorganized into distinct Swift extensions (BackingConfiguration, MemoryFile, Progress, Reading, Writing, ZIP64, and Deprecated) to improve maintainability and platform compatibility. A key behavioral change is the introduction of in-memory archive support for Swift 5.0+ on macOS, iOS, tvOS, visionOS, watchOS, and Linux, allowing archives to be created and manipulated directly from \Data\ objects without disk I/O. The public API has been updated to deprecate non-throwing initializers and \UInt32\-based buffer size parameters in favor of throwing initializers and \Int\ types, while also introducing progress reporting and cancellation support for read, write, and remove operations.

The Xcode project has been updated to include explicit Info.plist files for the main framework and test bundle, ensuring proper versioning via CURRENT\_PROJECT\_VERSION. A privacy manifest (PrivacyInfo.xcprivacy) is now bundled and copied during the build phase to comply with modern iOS/macOS privacy requirements. The project structure has been reorganized to support ZIP64 archives, with dedicated source files (Archive+ZIP64.swift, Entry+ZIP64.swift) and corresponding test suites (ZIPFoundationArchiveTests+ZIP64.swift, etc.) added to the build. Deprecated API wrappers (Archive+Deprecated.swift, FileManager+ZIPDeprecated.swift) are now explicitly included, signaling a transition away from older initialization and compression methods. Test coverage has been expanded with new files for memory operations, error conditions, and file attributes, while build settings have been adjusted to support visionOS and enforce stricter platform deployment targets.

Added Linux test runner for ZIPFoundation; Added test resource files for zero-size entry error conditions; Added unit tests for ZIP64 support and archive error conditions.

ZIPFoundation is now available via CocoaPods (version 0.9.20) alongside its existing Swift Package Manager integration. The new podspec configures the library for iOS 12.0, macOS 10.11, tvOS 12.0, watchOS 2.0, and visionOS 1.0, and includes a privacy manifest resource bundle. The SPM package manifest defines the core target and tests, conditionally linking the system zlib library on platforms that do not support the native Compression framework.
