Crash when presenting UIImagePickerController

Answered

This code crashes on iOS in Fullstory 1.55.0, but does not crash in Fullstory 1.54.0:

let cameraViewController = UIImagePickerController()

cameraViewController.sourceType = .camera

let presentCamera = { [weak self] in

   DispatchQueue.main.async {

       cameraViewController.delegate = self?.cameraImagePickerManager

       self?.sourceViewController.present(cameraViewController, animated: true)

   }

}

presentCamera()

I have confirmed Fullstory is the culprit by isolating my upgrade to 1.55.0 as the only change when causing the crash. Here is the stack trace:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={0, 0}, scale=3.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer to avoid this assert.'

    Hi Adam Johns,

    Thanks for reaching out about this!

    We have recently been made aware of this issue and we're currently working on a fix that will go out with our next release (1.56.0) next week.

    This issue only appears to affect SDK version 1.55.0 (as you noted) and causes a crash whenever the camera is opened on iOS 17 and 18. Excluding CAMViewfinderView has worked well to prevent crashes as an interim solution in the meantime.

    For further updates, keep an eye on our release notes page here: Fullstory for Mobile Apps Release Notes.

    All the best,
    Allegra

    Allegra Anka thanks for the quick response. Could you explain what you mean by excluding CAMViewFinderView? Do you have a code snippet? Do you mean setting showsCameraControls to false and then making my own custom camera controls?

    Hi Adam Johns ,

    You can create an exclusion rule by following these steps:

    1. Navigate to Settings > Data Capture and Privacy > Privacy.
    2. Within the Element Data Capture Rules section, click on Create Rule.
    3. Add a rule to exclude CAMViewfinderView.

    Let me know if you need further assistance!

    Best,
    Uday

    Hi Allegra Anka
     

    Do you have an update on when this fix will be released? The work around does not work for us and the image picker is being triggered by a webview, and we can't turn off the tracking for the webview.

    Hi Gareth Lloyd ,

    The fix is now available in v1.56 of our SDK, which was released yesterday. Please update to this version and let us know if it resolves your issue.

    Thanks,
    Uday
