I have an app which uses beacons it works well in iOS 10 and lower.
I'm trying to move it to iOS 11 but I alwayd get Error Domain=kCLErrorDomain Code=4 "(null)"
I ask for requestWhenInUseAuthorization.
Just baffled why it works in iOS 10 but not iOS11.
Is it a known problem? I cannot tell from the Release Docs.
Thanks

I'm having this issue also - if user selects ""only when using the app" from the locations permissions prompt, my beacons don't start ranging and I get the same error you're getting.
I wonder if beacon support requires "Always" permissions?
It appears that requestWhenInUseAuthorization permission does not allow you to monitor beacon regions - you can only range.
Our code was set up to monitor beacon regions, then start ranging beacons if the user entered a beacon region.
This will not work with requestWhenInUseAuthorization; startMonitoringForRegion will fail.
I suppose all we can do with requestWhenInUseAuthorization is to range continually (which would only happen if the app is in the foreground, so hopefully battery life won't be adversely affected).
