// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

// MARK: - SPM Source Distribution
//
// This package provides source distribution for Texture with Swift Package Manager.
//
// Features:
//   - Core AsyncDisplayKit (all nodes, layout specs, TextNode2)
//   - PINRemoteImage integration
//   - IGListKit Swift wrapper (TextureIGListKitExtensions)
//
// IGListKit Integration:
//   The native Objective-C IGListKit API (IGListAdapter+AsyncDisplayKit, etc.) is disabled
//   because it requires conditional compilation flags (AS_IG_LIST_KIT=1) which create
//   Objective-C headers that cannot be bridged to Swift. Instead, use the Swift wrapper:
//
//   - Import: TextureIGListKitExtensions
//   - API: adapter.setCollectionNode(node) instead of adapter.setASDKCollectionNode(node)
//   - See Sources/TextureIGListKitExtensions/README.md for complete API mapping
//
// Other Limitations:
//   - Video/MapKit/Photos features not accessible (require framework linking)
//   - Old TextNode disabled (use modern TextNode2)
