    I encountered a problem when I used version 3.1f of unity2019 to release. When I released ios in xcode, I could use iphone8p ios13.3 to run normally, and use iphone exr ios13.3.1 to flash back after a while. How can I solve this problem to release. When I released ios in xcode, I could use iphone8p ios13.3 to run normally, and use iphone xr ios13.3.1 to flash back after a while. How can I solve this problem,thank you

    I believe it is a bug that Unity has to patch. I am experiencing the same problem with iOS 13.3.1 here.

    Hi, would you mind posting your package manifests? Particularly what versions of ARFoundation, ARSubsystems, ARKit, XRManagement are being used.

    Also when you say `flash back after awhile` what is the behavior exactly? Is the background flashing white and then returning to the camera feed?

    Hello,

    Thanks for replying.
    iOS 13.3 target does not show in XCode 11.3. But it still works on 13.3 if i set it to 13.2 as we can see in the image.

    This is the error that i get when i try to run it on iOS 13.3.1. It basically quits the app as soon as i run it on 13.3.1. The same setting runs perfectly on my other device which is 13.3.

    I am also using the latest version of Unity, AR Foundation etc etc.

    Please let me know if you need more info.
    Thank you.

    We have tried to reproduce and are unable to do so with the devices on hand. Can you please submit a bug via the bug tracker and include your project?

    Additionally, would you include the exact version of XCode you are using to build the project?

    Hey, buddy, I've solved the problem, the application doesn't crash anymore, you can try another version of xcode. I'm not sure what the problem is

    In unity 2019, 2.2f will be released perfectly, which should have nothing to do with xcode

    Hey! Thank you for sharing your solution.

    It did not work for me unfortunately. My project was build with 2019.3.
    It gave me error because unity doesn't support downgrading projects.
    Did you have problem downgrading?
    I am assuming that you created an empty project with 2019.2 and it worked with iOS13.3.1?

    Also, your video is spot on. The app opens for a brief moment, with a black screen. It then returns to the home page.
