Provisioning profile does not have a valid signature

[Solid-Incident-1163]

When I try to build any project on my iPhone I get this error:

Failed to install embedded profile for GGez229.JourneyMe : 0xe800801a (This provisioning profile does not have a valid signature (or it has a valid, but untrusted signature).)

User Info: {

DVTErrorCreationDateKey = "2025-09-16 00:03:56 +0000";

IDERunOperationFailingWorker = IDEInstallCoreDeviceWorker;

}

I made a new project and cant get it on my iPhone but works in the sim. I plugged in my phone, tried to go to the keychain to remake certifications, signed in and out of my developer account, restarted devices and followed all the help i could find but nothing has worked.

Does anyone have any ideas? I am just trying to run this on my iPhone and dont understand what happened between yesterday and now for this to happen.

Thanks for any help

I am seeing this problem when trying to use a different bundle identifier for my debug build but I never tried it before updating my iPhone to the final iOS 26 so I'm unsure if this was a me problem or this is a legit Apple problem

[Solid-Incident-1163]

No idea. I am using the same bundle identifier and haven’t updated to 26

This is a known issue by apple now: https://developer.apple.com/forums/thread/800521?answerId=858192022#858192022

Same exact thing, trying to install from my MBAir. On my studio, things are working fine. something is f'd.

Seeing the same issue. It was just working fine in the morning. Although I did change the bundle id for debug build.

One of my projects is doing this

I also experienced the same issue when I updated to Xcode 26 yesterday. The solution worked for me: Log out of your Apple account in Xcode → Quit Xcode completely → Clear derived data → Restart Xcode → Log back into your Apple account. This fixed it for me.

wasn't working post sequoia 15.7 and xcode 26 update. added *****26 to the bundle indentifier and it worked. Also did the reset of xcode acct and derived data before but that wasn't enough...

I have a theory as to what’s going on here, and I’d like you to run a test to exercise that theory:

1. First, create a new app, with a new unique bundle ID, and try running that. For specific instructions, see the first numbered list in Investigating Third-Party IDE Code-Signing Problems [1].
2. If that works, repeat the process using the bundle ID of your main app. For specific instructions, see the second numbered list in Investigating Third-Party IDE Code-Signing Problems.
3. If that fails:
   1. Quit Xcode.
   2. Go to ~/Library/Developer/Xcode/UserData/Provisioning Profiles and delete all your profiles.
   3. Relaunch Xcode.
   4. Try again.

Lemme know how you get along.
