Build the iOS remote app

Build for the simulator

make ios

This regenerates the Xcode project with XcodeGen and builds for the iOS Simulator. For a real device, use make ios-device, but you need to set up code signing first (see below).

Required identifiers

This app ships a notification service extension that decrypts Attention pushes before iOS displays them, so it needs two App IDs registered in the Apple Developer portal, not just one.

The extension itself needs no capability. It only receives notifications, and the keychain-access-groups entitlement it uses to read the pairing secret is satisfied by that entitlement alone, unlike App Groups.

Changing the developer team

The signing defaults (DEVELOPMENT_TEAM and MYTTY_BUNDLE_ID) live in ios/MyttyRemote/Config/Signing.xcconfig. Don't edit that file directly; create Config/Local.xcconfig to override it instead.

cd ios/MyttyRemote
cp Config/Local.xcconfig.sample Config/Local.xcconfig

Then edit Config/Local.xcconfig and set DEVELOPMENT_TEAM and MYTTY_BUNDLE_ID to your own values. Override MYTTY_BUNDLE_ID, not PRODUCT_BUNDLE_IDENTIFIER.
