Building SampleFireall.app from WWDC 2019 on Big Sur Xcode 12.4

Watching this

Anyone succesfully build this with the tools/versions in the title?

I get a bunch of Redefinition of module 'AppleTextureEncoder' in module.modulemap.
In addition to AppleTextureEncoder I see:
'Compression'
'Darwin'
'asl'
'dnssd'
'launch'
'os'
'os_object'
'os_workgroup' (and on and on).

Finally, build fails with:
"No such module 'NetworkExtension'.

I just tried building SimpleFirewall here in my office and it was surprisingly easy:
  1. I opened the project in Xcode (I’m using Xcode 12.5 on macOS 11.3).

  2. I switched the code signing for both targets to my team.

  3. I selected the app scheme (SimpleFirewall) and my Mac as the destination.

  4. I chose Product > Build.

It built just fine. There wasn’t even any warnings! (Well, there was the Validate Project Settings stuff, but that’s normal).

Share and Enjoy
