- Ensure that you construct a valid
uuidby importing theuuidlibrary and runninguuid.v4()as shown in the examples. If you don't do this and use a custom string, the incoming call screen will never be shown on iOS. - On iOS, calls fail in the Simulator: it has no CallKit service. Test calls on a device (the app itself starts in the Simulator). Android emulators support calls.
