iOS Simulator crashes after stoping and re-run the app.

kikikimbing commented 2 weeks ago

When running on the iOS simulator, after granting location permission to 'Always allow' and calling bg.BackgroundGeolocation.start() followed by bg.BackgroundGeolocation.stop(), I stop the app. However, when I try to run the app again on the same simulator, it fails to attach and crashes.

I can run my app on simulator again after i delete and rebuild it again.

Actual Behavior

The simulator crashed and failed to attach after I re-run the app.

Steps to Reproduce

Grant permission to Always Allow
Call bg.BackgroundGeolocation.start() followed by bg.BackgroundGeolocation.stop()
Stop the app
Re-run the app
