@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 Error Domain=com.apple.dt.deviceprep Code=-27 "Browsing on the local area network for iPhone, which has previously reported preparation errors" UserInfo={NSUnderlyingError=0x60000bf8e670 {Error Domain=com.apple.dt.CoreDeviceError Code=1000 "The specified device was not found."

(Underlying Error: A connection to this device has not been established.)) 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 :)

Clearing trusted computers not working for me. Previously I posted this same issue here https://developer.apple.com/forums/thread/737286 (was unaware of this thread) From debugging the issue, found that its an issue of memory leak for CoreDeviceService Sandbox (Process that manages device communication)(loglines in above attached post) This same issue is also faced when executing xcuitest with test-without-building flag (Xcode tries to install test app before test execution). Killing CoreDeviceService process or rebooting the host machine instantly resolves the issue but on a downside. All the connection to the device breaks and hence all running xcuitests also breaks. Issue reappears after few xcuitest execution.
