This is an old question but maybe somebody can find useful the next link where it is explained how to debug the NSE or NCE. In my case I could catch errors and see my print statements. https://medium.com/tiendeo-tech/how-to-debug-ios-extension-d8841f998db4

I fixed this problem updating my GoogleMaps pods: pod 'GoogleMaps', '8.3' And setting translatesAutoresizingMaskIntoConstraints to false: mapView.translatesAutoresizingMaskIntoConstraints = false

I forgot to say that this happens when a marker is tapped and this should load a customInfoWindow but the app crashes in some devices: let customWindow = Bundle.main.loadNibNamed("InfoWindow", owner: self, options: nil)![0] as! CustomInfoWindow' So far the crash happens on iOS 15.8 (iPhone 7 plus) and 17.1.2 (iPhone 15 Max Pro) but it works in iPhone 11, 12 y 14
