Compiler error: Invalid library file - CoreLocation

Question

I have one of my application, that is created in Xcode 8. I have used CoreLocation and MapKit in that app.

I have update app with latest iOS till now. and it was working fine. Now I am updating application with iOS 1. So I hvae opened app with Xcode 11.0 and updated all the required code. Also updated setting that is suggested by Xcode "Perform Changes" and all that.

Now I run application, but I am getting error like :

Compiler error: Invalid library file.

I have searched lot, but can't find any solution. Is this a bug in new Xcode or new iOS ?

Is there anything I have to do extra changes or settings ? Please guide me. Is this known bug by Apple ?

Answer 1

I'm seeing this issue also. It only happens if you implement the renderFor overlay for MKMapView. And without this function, I can't display the polyline that I'm adding to the mapView. This was working fine in Xcode 10.

Answer 2

Hope this will be fixed in the next version of xcode. But this only happens on the simulator. Use your real device for testing for now..

Answer 3

For me what works is to disable OS Activity Logging.

Add the Environment Variable: OS_ACTIVITY_MODE with value: disable on Product > Scheme > Edit Scheme > Run > Arguments.

Warning

Folks have reported that other useful logs for them have also been silenced.

Taken from a similar answer I gave regarding WKWebView, but reposting here for visibility after finding the logging noise appears also with MKMapView.

Answer 4

I started running into this error recently and was able to get it to go away by clearing the Simulator from Hardware->Erase All Content and Settings... menu item.
