iOS 15 Untrusted Developer issue

Question

I have updated recently to a new iOS 15 and after I built and run my application in Xcode, while have been logged in with a same developer account as before iOS 15 installation, I get this message:

The operation couldn’t be completed. Unable to launch com.xyz.xyz.xyz because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user.

and the error log:

Could not launch “my-project0name” Domain: IDEDebugSessionErrorDomain Code: 3 Failure Reason: The operation couldn’t be completed. Unable to launch com.xyz.xyz.xyz because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user. User Info: { DVTRadarComponentKey = 855031; IDERunOperationFailingWorker = DBGLLDBLauncher; RawUnderlyingErrorMessage = "The operation couldn\U2019t be completed. Unable to launch com.xyz.xyz.xyz because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user."; }

System Information

macOS Version 11.6 (Build 20G165) Xcode 13.0 (19234) (Build 13A233) Timestamp: 2021-09-21T12:36:18+02:00

Earlier (on iOS14), this could be solved by going to:

Settings.app -> General -> Profile -> Select Profile -> Trust

But now (on iOS15) I can't actually find it at that location. How would I fix this?

Answer 1

From what i understand, this might be a bug connected to iOS 15 / xcode 13.

I found a solution which is to create a new Apple ID and use it to sign your app in xcode.

You can add a new team by going into "Signing & Capabilities"-tab and select "Add account" where you select a team.

Once you've done this and run the application on your device again, the option to trust the application in Settings > General > Device Management should appear!

As @ujell pointed out. 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.

Answer 3

Indeed, it looks like, the problem occurs only with IOS >hardware< real devices running >= iOS 15

I see no option in Settings allowing me to set the app dev as trusted.

This does NOT occur with my older (real) iPad Air, running with iOS 12.5. The app runs immediately without prompting for trust etc.

It also runs without problems on Xcode's simulator devices with iOS 15. So yes, I think it is an iOS 15 and/or Xcode issue. reported this to Apple.

Answer 4

Ios15 changes trusted application position to:

settings -> general -> vpn and device manage

then you can see your application under the Developer App, click it and verify it
