initialize_from_file unknown #114

bryanaamot commented 2 years ago

After running this: gryphon init SampleApp.xcodeproj/

I get this error:

Error making gryphon targets: Ruby version 3.1.1 /usr/local/Cellar/gryphon/0.18.1/libexec/vendor/gems/xcodeproj-1.16.0/lib/xcodeproj/project.rb:227:in initialize_from_file': [Xcodeproj] Unknown object version.

Hey @bryanaamot, thanks for opening this issue. I've looked at the Xcodeproj code to try to figure out what's going on, but didn't understand much.

Can you share more information about the app you're trying to initialize? What Xcode and Swift versions are you using? Is it just a clean Xcode template or did you make any changes to it? Were you following the steps in the tutorial?

I am seeing this same error message in Terminal. I was following the tutorial up until "Step 3: Initialization" when I got the following error in terminal:

MyAwesomeiOSApp % gryphon init MyAwesomeiOSApp.xcodeproj

@bryanaamot, I Resolved the build issue by re-installing xcodeproj via sudo gem install xcodeproj, as stated in the tutorial.
