XCode 11 crash after adding iOS 14 device support

Question

My XCode version is 11.1 and the iPhone OS version is 14.0.1. To run apps on iOS 14 device, it requires XCode 12.

An alternate option to support iOS 14 in XCode 11, is to add Device Support. So I have added Device Support for iOS 14 in the following way -

Goto Applications > Xcode > Right Click > Show Package Contents > Contents > Developer > Platforms > iPhoneOS.platform > DeviceSupport

Then added the device support files in this directory.

Device Support files are available here - https://github.com/filsv/iPhoneOSDeviceSupport

After adding Device support, whenever I try to run it on the iPhone device, it instantly shows a 'Build Successful' message, then XCode crashes.

Here is the build error log -

Hi @matt, Upgrading XCode or Mac OS is not possible due to some security reason. That is why I am trying with existing resources. — Biswajit Karmakar, Apr 05 '21 at 10:53
I have upgraded my iPhone OS to 14.4.2. Now I have been facing another problem when trying to run from Xcode 11, it shows 'Unable to copy symbols from this device'. — Biswajit Karmakar, Apr 05 '21 at 10:54

There has been a security enhancement that stops Xcode 11 working with iOS 14 (the probable underlying reason causing the crash) but there is a workaround (and lots of other helpful information) at https://betterprogramming.pub/debugging-on-ios-14-with-xcode-11-d332f12f49dd which explains how to launch, log and debug.

I've had that kind of problem myself. Try out https://stackoverflow.com/a/39029595/2715565 to see if it helps. – Faisal Memon Apr 05 '21 at 16:20
Thank you for sharing the link. I have tried all of this but doesn't work. I have been facing this problem 'Unable to copy symbols from this device'. Smilar problem https://github.com/iGhibli/iOS-DeviceSupport/issues/134 – Biswajit Karmakar Apr 06 '21 at 06:29
One way to narrow it down is to pull off the console logs from the phone. If you can do that and share the console messages at the time of the problem, it could point to where the problem is. Also, is your cable an Apple-manufactured one, and is it directly connected to the computer (no hubs)? It can be glitchy if otherwise. – Faisal Memon Apr 06 '21 at 20:03
