Open Source Swift Emulators

PlayCover is an open-source macOS application that restores the ability to run iOS apps and games on Apple Silicon Macs (M1/M2/etc.). It simulates an iPad environment to enable native app execution and offers custom input mapping, making it especially useful for gaming and sideloading on macOS.

Games are loaded from your iPhone's documents directory. In iTunes, drop .gb or .gbc files into the Giovanni app documents folder, and they'll show up automatically on your Apple Watch. When you play a game for the first time, it'll download to your watch and get cached in the watch's documents directory. Subsequent loads are immediate. Emulator saving and loading is automatic and happen whenever the app gets closed/inactivated or opened/activated. In-game saving and loading is completely separate. If for some reason the emulator save gets corrupted, force-touching the screen will bring up the option to reset the emulator, allowing you to resume your in-game save.
