TLPhotoPicker is an iOS library providing a customizable photo and video picker UI similar to Facebook's picker. It wraps the Photos framework (PHAsset, PHAssetCollection) and offers a configurable grid view with support for smart albums, live photos, video playback, iCloud download, and camera capture. The architecture follows a service-oriented pattern with separate classes for photo library access, selection logic, camera handling, and video playback, all coordinated by a central view controller. The library includes a builder pattern for configuration, async/await support for image loading, and comprehensive delegate callbacks. It is distributed via CocoaPods and Swift Package Manager, targeting iOS 13.0+. The codebase is well-structured but shows some technical drift, notably continued use of the deprecated UIImagePickerController for camera capture instead of the modern PHPickerViewController.
