I've managed to solve the same problem for MKMapView. Apparently, that happens when your app's current permissions state doesn't correspond to entitled (declared in Info.plist) one. That effecively means that you need to call APIs to gather user's permissions explicitly and preemptively. (E.g. LocationManager.requestWhenInUseAuthorization before displaying a map with user location on it)

same error, totally different scenario (transforming a UIImage)

libMobileGestalt MobileGestalt.c:550: no access to InverseDeviceID (see rdar: //problem/11744455)

For me it appeared to come from setting the result of the below as a UIImageView.Image - the crash only happens when the UIImageView property gets set:

func ... (image: UIImage, transform: CGAffineTransform) -> UIImage? { var coreImage = CIImage(image: image!)

    if coreImage == nil {
        if let cgImg = image!.cgImage {
            coreImage = CIImage(cgImage: cgImg)

   if coreImage != nil {
        //returning UIImage(ciImage) causes [ibMobileGestalt MobileGestalt.c:550: no access to InverseDeviceID (see <rdar://problem/11744455>)] 
        return UIImage(cgImage: cgImage!)

        //creating a CIImage prevents the crash, but renders blank image (not nil)
        coreImage = coreImage!.applying(transform)

        let context = CIContext()
        let cgImage = context.createCGImage(coreImage!, from: coreImage!.extent)

        return UIImage(cgImage: cgImage!)

        //returning the original UIImage (as expected) has no problems
        return image
    } else {
        //fall back if nothing's worked!
        return image


I'm new to CGImage and CIImage, if the obviously wrong, any pointers would be great.

I was trying to keep the image manipulation at least one step away from the GUI code, but looks like I'll need to apply the transforms to the UIImageView rather than manipulating the UIImage before introducing it to the GUI.
