Hello team, On Xcode 14.1, After building the project and when the simulator launches, it shows blank black screen. Here steps to reproduce:

  1. build the project with fresh device. Try changing the language to French in device settings
  2. Device should launch in French language. Instead, it loads and goes blank (blank screen)
  3. Quit the simulator (XPC error is displayed) and rebuild the project using the same simulator device.
  4. Build succeeds and simulator launches, but has blank screen on simulator.
  5. Xcode is stuck at "Launching Application"

Is this a known issue? Has anyone experienced the same? How can I fix this? Stack (https://stackoverflow.com/questions/74315983/xcode-stuck-on-launching-application) says its a bug, so posting here for recommendations

We believe that the primary issue causing this behavior is addressed in Xcode 15.0.1. Please update to Xcode 15.0.1 and see if that addresses the issue for you. If it doesn't, please file a bug report with Feedback Assistant including:

1 - sysdiagnose captured while in the state. 2 - xcrun simctl diagnose captured while in the state

@jeremyhu Xcode 15.0.1 does not fix the issue to me, I can reproduce it quite consistently. But I also don't see any mentions of this in the official release notes? https://developer.apple.com/documentation/xcode-release-notes/xcode-15_0_1-release-notes

Are you sure that's the version it's supposed to fix this issue? 🤔

In order not to kill the simulator every time after rebuild, I will kill the app before rebuild.

or you could make a script to do this job,make a key bindings to run the "kill app behavior" script just like:

#!/bin/sh
# set you bundle identifier
bundle_id=com.***.***
# find running device
device=$(xcrun simctl list | grep 'Booted' | awk -F'[()]+' '{print $2}')
# terminate it
#xcrun simctl terminate $device $bundle_id

array=( com.Addcn.car8891 com.addcn.newcar8891 )
for i in "${array[@]}"
do
    xcrun simctl terminate $device $i
done
