• Add PrivacyInfo.xcprivacy privacy manifest (declares no tracking, no data collection, no required-reason API usage)
• Bundle privacy manifest in both SPM targets and CocoaPods
• Update CocoaPods deprecation notice with trunk shutdown date (December 2, 2026) (https://blog.cocoapods.org/CocoaPods-Specs-Repo/)

A major release with a full rewrite of the Swift implementation. The Objective-C implementation is unchanged.

Highlights

• Swift rewrite — The entire Swift source has been rewritten from scratch to align with the Objective-C reference implementation, following modern Swift conventions.
• Platform bump — Minimum deployment target is now iOS 13 / tvOS 13.
• Apple-style documentation — Every public member now has full DocC-compatible documentation comments.

New Features

• headerInset / footerInset properties — Control margins around section headers and footers independently.
• minimumContentHeight property — Set a minimum content height for the collection view (useful for hidden headers with no content).
• Delegate methods — insetsForHeaderIn:, insetsForFooterIn:, minimumColumnSpacingFor: for per-section customization.

Improvements

• All property setters now skip invalidateLayout() when the value hasn't changed.
• Replaced deprecated UIScreen.main.scale with traitCollection.displayScale for pixel-alignment calculations.
• layoutAttributesForSupplementaryView(ofKind:at:) now accepts both CHTCollectionElementKind* and UICollectionView.elementKindSection* strings.
• layoutAttributesForElements(in:) deduplicates attributes by index path, preventing potential duplicates.
• Eliminated all force-unwraps of collectionView! — the layout now returns early safely when collectionView is nil.
• Union rects optimization now uses a proper union of all rects in each batch, not just the first and last.
• Demo projects modernized with programmatic UI and UIScene lifecycle (storyboards removed).
• CI updated to Node.js 24 compatible GitHub Actions.

Breaking Changes

See the migration guide in the README for full details. Summary:

• Deployment target: iOS 9 → iOS 13, tvOS 9 → tvOS 13.
• Swift toolchain: swift-tools-version 5.0 → 5.9 (requires Xcode 15+).
• Supplementary view element kind: Headers/footers now use CHTCollectionElementKindSectionHeader/Footer instead of UICollectionView.elementKindSectionHeader/Footer.
• Return type: layoutAttributesForSupplementaryView(ofKind:at:) now returns UICollectionViewLayoutAttributes? (optional).
• Removed: Public delegate property (now private).
• Removed: All @available(*, unavailable, renamed:) migration shims from 0.9.x.
