TTGTagCollectionView is a production-ready iOS UI library that renders collections of tags/chips in a flowing, wrap-aware layout. The two principal entry points are `TextTagCollectionView`, which displays styled text tags driven by a datasource of `TextTag` model objects, and `TagCollectionView`, a generic container for arbitrary `UIView` tags using a delegate/datasource pattern. Tags are plain in-memory model objects — there is no persistence, networking, or data pipeline. The library is Swift-first with an intentional `@objc` compatibility surface preserving the pre-3.0 Objective-C API, and it ships with CocoaPods and Swift Package Manager support plus a `TagCloudView` SwiftUI wrapper.
