Comments

1. Manually, It works perfectly in appium desktop version 1.12.1
2. I tried with various Xcode Versions ; but nothing helped(got errors like Couldn't identify simulators with particular versions. But they are actually installed)
3. Tried removing capabilities "useNewWDA" and reduce the delay for capabilities("wdaEventloopIdleDelay & eventLoopIdleDelay)

I know, there are similar bugs corresponding to this post; but solutions doesn't work for me.
Need Help Pls!
