PMKVObserver
A thread-safe and type-safe block-based wrapper for Key-Value Observing in Swift and Objective-C.
What is PMKVObserver?
PMKVObserver is a modern, block-based wrapper around Apple's Key-Value Observing (KVO) API for iOS, macOS, watchOS, and tvOS development. It provides a safer and more convenient alternative by eliminating common pitfalls like manual observer removal, thread-safety issues, and dangling references. The library offers automatic cleanup when observed or observing objects deallocate and includes strong typing support in Swift.
iOS, macOS, watchOS, and tvOS developers using Objective-C or Swift who need to implement Key-Value Observing in their applications. It is particularly useful for developers who have experienced crashes or complexity with native KVO APIs and want a more maintainable solution.
Developers choose PMKVObserver over native KVO because it provides thread-safe observer registration and cancellation, automatic unregistering to prevent crashes, and a block-based API that improves code readability. Its unique selling point is the combination of safety features like automatic cleanup with strong typing in Swift using KeyPath, reducing runtime errors.
