Open Source Swift Games for Apple iPhone

FlappySwift is a Swift reimplementation of the famous “Flappy Bird” game, intended as a tutorial or demo to teach game development fundamentals on iOS. The project includes sprite rendering, physics, collision detection, scrolling background, user input (tap to flap), scoring, and game-over logic, all wired together in a simple but playable form. Because the code is real and running, learners can modify gravity, speed, obstacle spacing, or visual assets to see how design decisions impact feel and difficulty. The repo often includes instructions for building and running on the simulator or device, as well as commentary on how components are structured (game loop, scene management, layering).

SwiftGodot provides Swift language bindings for the Godot 4.2 game engine using the new GDExtension system (for 4.1 compatibility, use the 4.1 branch, preview for upcoming 4.3 release is in the 4.3 branch). SwiftGodot can be used to either build an extension that can be added to an existing Godot project, where your code is providing services to the game engine, or it can be used as an API with SwiftGodotKit which embeds Godot as an application that is driven directly from Swift. SwiftGodot allows developers to take new and existing Swift packages and use them as extensions for the Godot game engine.
