Clone this repo then run either cargo run --bin ios or cargo run --bin android. This command will build either an xcframework or a jniLibs folder containing libraries for the device and simulator. After this you can build in xcode/android studio without needing to run a cargo command again. Open the contents of ios or android to build the apps.
To build a release binary use the following commands:
# CONFIGURATION is either debug or release
CONFIGURATION=release cargo run --bin ios
CONFIGURATION=release cargo run --bin android
