Xcode 13 on iOS 15 Beta 'Untrusted Developer' error on iPhone XS device

I have been testing my iOS app on my physical iPhone XS for quite some time now and all of a sudden it threw an error when I tried to run it saying:

"APP NAME" is no longer available.

So I went to re-build via Xcode into my device again to reinstall it. But I was getting an error message saying "Untrusted Developer".

So I tried to go to the Settings > General > VPN and Device Management screen to see if I need to ‘Trust’ my own developer profile again. But it’s not appearing on that screen or any other new developer profile for that matter.

Did a bit of research and tried to troubleshoot. One of the solutions I’ve found and worked was to actually create a new developer account and use that to build and install the app on my device. I does work but I don’t want to use another developer account to to build this app as the bundle identifier that I wanted to use was already tied up to that old account. And I have a bunch of other apps tied up to that old account as well.

The other reason why the above solution also wouldn’t be ideal as I already have months worth of data in my device that was saved in that app. If created a new build using a new account it wouldn’t be able to access the data of the old app built using the other account.

Just to note, that old account was formerly a paid account but now it expired. But I didn’t have that problem until recently. So I am guessing it has something to do with the recent iOS 15 beta builds.

I will be filing a bug report for this. But does anyone have any idea or workaround to get rid of this issue? Any information that could potentially point me towards the right direction would be appreciated. Thanks!

I’ve filed this as a bug on AppleFeedback Assitant. They’ve reached out to me to ask for logs and the certificate I used to re-build the project. I’m guessing this this a bug and they are trying to fix it.

    I managed to fix this issue.

    Xcode -> Preferences -> Accounts -> Manage Certificates -> + -> Apple Development and then make a new certificate

    My situation might be different from yours but here were the symptoms I was seeing. I was able to sign random Github projects and run them on my phone. I also have a paid developer account. I never saw anything related to my app in the VPN & Device Management settings on my iPhone and I still don’t.

    I had the same error on my iphone 12 promax, You just need to create a new bundle identifier then build and then change back to the old bundle identifier. It works for me

    I think I found solution for this problem.

    You need to remove old certificate from your keychain, after then create new in Preferences... -> Accounts -> Manage Certificates... -> Tap +

    I hope I will help someone.

    iOS 15 + macOS Monterey + Xcode 13 Seems to have fixed the issue

    After updating to macOS Monterey, my app launches as normal. I will add that I did all the things that other people which might’ve changed the outcome. This included changing my bundle identifier and deleting my certificate from the key chain and creating a new one. I’m also running Xcode 13.1, iOS 15.1, and macOS 12.0.1.

    The provisioning profile generated prior iOS 15 is preventing installation on the new release. Therefore, you will need to generate a new provisioning profile for your app. Try the following:

    • Quit Xcode
    • Go to the directory of cached provisioning profiles (cd
      ~/Library/MobileDevice/Provisioning Profiles/)
    • Back up the existing
      files to another directory
    • Remove all profiles listed under
      ~/Library/MobileDevice/Provisioning Profiles/
    • Launch Xcode
    • Install/run the app on your device

    Xcode will detect that there are no eligible profiles on your local system and request a new one during the next build to a device. The new profile will be compliance with iOS 15 provisioning.

    NOTE: if it still doesn’t work, then install the iOS 15.2 beta release (Build 19C5026i or later) on your device and try the steps above again.
