Exc_bad_Access after upgrading to Xcode 8.3 and iOS 10.3

Question

Hi all,After upgrading to XCOde 8.3 and iOS 10.3 and my iPhone, my project is not working anymore.When selecting an annotation on my map, the app crashes and this line is highlighted in the debugger:func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {The crash log is this one:Version:             1 (1.0)Code Type:           ARM-64 (Native)Role:                ForegroundParent Process:      launchd [1]Coalition:           app.TEST.test [1370]Date/Time:           2017-03-29 11:34:09.4286 +0200Launch Time:         2017-03-29 11:33:38.3835 +0200OS Version:          iPhone OS 10.3 (14E277)Report Version:      104Exception Type:  EXC_BAD_ACCESS (SIGSEGV)Exception Subtype: KERN_INVALID_ADDRESS at 0x000000016fc5b690Termination Signal: Segmentation fault: 11Termination Reason: Namespace SIGNAL, Code 0xbTerminating Process: exc handler [0]Triggered by Thread:  0Filtered syslog:None foundThread 0 name:  Dispatch queue: com.apple.main-threadThread 0 Crashed:0   TEST                         0x0000000101c2a3f0 0x100098000 + 289105761   ???                           0x000000016fd39f48 0 + 61711071442   TEST                         0x0000000101f6f93c 0x100098000 + 323402843   MapKit                         0x0000000195f23888 -[MKMapView annotationManager:didSelectAnnotationRepresentation:] + 7644   MapKit                         0x0000000195ee417c -[MKAnnotationManager selectAnnotation:animated:avoid:] + 7205   MapKit                         0x0000000195f15cdc -[MKMapView _handleSelectionAtPoint:] + 5526   UIKit                         0x000000018ff47c54 -[UIGestureRecognizerTarget _sendActionWithGestureRecognizer:] + 647   UIKit                         0x000000018ff4b488 _UIGestureRecognizerSendTargetActions + 1248   UIKit                         0x000000018fb05540 _UIGestureRecognizerSendActions + 2529   UIKit                         0x000000018f9a745c -[UIGestureRecognizer _updateGestureWithEvent:buttonEvent:] + 72010  UIKit                         0x000000018ff3b72c _UIGestureEnvironmentUpdate + 98811  CoreFoundation                 0x00000001897f49a0 __CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ + 3212  CoreFoundation                 0x00000001897f2628 __CFRunLoopDoObservers + 37213  CoreFoundation                 0x00000001897f2a74 __CFRunLoopRun + 95614  CoreFoundation                 0x0000000189722d94 CFRunLoopRunSpecific + 42415  GraphicsServices               0x000000018b18c074 GSEventRunModal + 10016  UIKit                         0x000000018f9db130 UIApplicationMain + 20817  TEST                         0x0000000100ac54d8 0x100098000 + 1067132018  libdyld.dylib                 0x000000018873159c start + 4I've no idea what can happen here.Any help would be appreciated.My code works fine on XCode 8.2.1 and iOS 10.2.1 (but I can't downgrade...)Regards,Alex

I am getting the same problem with Xcode 8.3.1 and a MacOSX app.I am going try to downgrade to Xcode 8.3 to see if that will help.For what it is worth, I get the problem when I compile a release binary, with symbols stripped.The Debug version of my App works fine.bob...
