Sorry about the delay @BhavinSuthar https://github.com/BhavinSuthar . I finally got to try this on an iPad running 17A5831C build of iOS. And, my Xcode version is Version 11.0 (11A419c), which I believe is what you are using. If not, please use this version (it is available on developer.apple.com).

Unfortunately, I could not repro the failure 😦

Here are the logs:

I highly doubt there’s a hardware-specific bug here, but, the next thing for me to try is using the hardware you are using for your tests. Could you please tell me the version of iPhone / iPad you are using for these tests?
