[Xcode15 Beta] ERROR: Failed to install the app on the device.

I was running into the same issue with several Xcode projects. Luckily, clean new projects would install on my devices just fine, and I could compare the two configurations. I tried adjusting various aspects of the project and targets, e.g. Project Format, Localisation, Identity.

The change that fixed it in the end was to specify "Bundle name" in the Info.plist:

<key>CFBundleName</key>
<string>$(PRODUCT_NAME)</string>

The issue you are experiencing is a result of a bug in a Core Device component. The bug leads to the system's sandbox memory eventually becoming exhausted, preventing Xcode (and other tools such as devicectl) from being able to install apps and perform other actions involving user-provided files and paths.

However, the good news is that this bug has been fixed as of Xcode 15.1, which is currently in beta. If you have a developer account you can grab it here: https://developer.apple.com/news/releases/

I know some of you don't use beta releases, but in this case you don't actually need to use it. It just needs to be run at least once. Once you download Xcode 15.1, run it once and let it install the additional components when it prompts you. This will update the Core Device components on your system and install newer versions which do not have the bug. You can then go back to using Xcode 15.

Please try this out and let us know through Feedback Assistant if you experience any issues. I promise you that we do read the reports.

@Developer Tools Engineer Thanks for the fix and update on the issue.

I tried using the 15.1 beta 3 xcode and found the Issue resolved (CoreDeviceService memory not getting exhausted after some time of test execution). Though, stepped into another issue now(find in below points).

• Ran 150-200 UI tests using xcodebuild test-without-building command.
• Suddenly, UI tests started failing with below error

• After this issue, app install also started failing with below error message

13:45:38  Enabling developer disk image services.
13:45:38  Acquired usage assertion.

ERROR: Timeout while connecting to remote device. (com.apple.mobiledevice error -402652910.)
         FunctionName = _AMDeviceCreateWithRemoteDeviceWithError
         LineNumber = 325

• Surprisingly, this issue got resolved in 3-4 minutes automatically but during these 3-4 min all tests failed, all app install failed.

Requesting to look into this new issue and fix in upcoming beta version.

Also, I am interested in knowing the root cause of CoreDeviceService memory exhaust issue and how this was related to app install failure :)
