This Xcode project contains the implementation of LinSpell spelling correction algorithm written on Swift. I also included the Objective-C version if it's needed for someone.
The speed of this algorithm is lower than original implementation in C# but primarily because of my limited knowledge of Swift programming language. From my opinion there are some ways to improve the performance.
Note: The app version with Release configuration will be faster than Debug. You can change the Optimization Level in Build Settings of your project to change this behaviour for debugging.
