YPImagePicker is an iOS framework that provides an Instagram-like photo and video picker with a rich set of features including camera capture, library browsing, video trimming, photo filters, cropping, and multiple selection. The architecture follows a modular pattern with a central configuration struct (YPImagePickerConfiguration) that controls all behaviors, and a navigation controller (YPImagePicker) that manages a paged interface (YPPickerVC) switching between library, photo, and video screens. The library screen uses PHPhotoLibrary and PHCachingImageManager for asset fetching and caching, while the camera and video screens leverage AVFoundation for capture. Filters are applied via Core Image, and video trimming uses the PryntTrimmerView dependency. The framework is highly customizable through configuration properties for colors, fonts, icons, wordings, and feature toggles. The codebase is well-organized into folders for configuration, filters, helpers, models, pages (gallery, photo, video), and selections gallery. Helper extensions provide reusable functionality for AVFoundation, Photos, UIKit, and Core Image operations. The permission management is abstracted into a dedicated module. While the framework lacks unit tests and some view controllers are large, the overall structure is clean and the separation of concerns is reasonable. The library has been widely adopted (4.4k stars) and is actively maintained with recent commits and pinned dependencies.
