has anyone here managed to build an iOS project on a Mac with a new Apple silicon?
We have a Mac Mini Developer Transition Kit equipped with the M1 processor, running mac OS Big Sur 11.0.1 RC and Xcode 12.2 RC.
With the previous versions of the OS and Xcode it was a huge mess even to compile the simplest thing, but as we are approaching the final releases the situation got better.
Despite this, we still have some major problems
the Unreal Editor crashes when you try to open the Project Settings. It seems to have something to do with the Metal render pipeline. (with all Xcode 12 beta versions)
the Unreal Editor hangs as soon as you open it, at “Finished discovering assets” (since Xcode 12.2, even with RC)
building an iOS project, either from Project Launcher or from command line with UAT, fails near the end of the Build command, when building the Asset catalog, with
Failed to launch IBCocoaTouchImageCatalogTool via CoreSimulator spawn Underlying Errors: Description: Failed to handshake with platform tool Failure Reason: Failed to open connection over FIFOs with platform tool Underlying Errors: Description: Recovery Suggestion: Try restarting your computer Underlying Errors: Description: Failed to open FIFOs for handshaking with platform tool Failure Reason: IBCocoaTouchImageCatalogTool exited before we could handshake
While we can still live without the editor (help is appreciated anyway if someone has found a solution!), the last problem is a hard stop.
Needless to say that the common solution “Clean the project and restart Xcode” doesn’t work.
I’ve tried various updates and clean install of Xcode, cleaning the Xcode project, removing the Binaries/Intermediate folders and .xcworkspace, deleting Xcode caches and derived data all around the system. The problem still persists.
This seems however a recurrent problem that accompanied Xcode over the years, so somebody may have already encountered it in the past.
Thank you for your help.
