You must select target with bundle type in your project :
Then you need just compile that target with
Cmd-B
orProduct -> Build
After that, you can find your bundle here:
File -> Project[Workspace] Settings
Tap on the arrow
And find next folder
DerivedData -> [YOUR_PROJECT_NAME-Random_Numbers] -> Build -> Products -> Debug-[SDK]
Also you can just right click on archive in Xcode in Product group and select Show in Finder
, but it was not the case for me
I followed the steps from repo you linked to create bundle target and then found it with steps I described above
