I peaked into the .gitignore file that was in the SwiftUI example projects and found this. Should I add it to the current swift,macos template I pull from git? I'm not so concerned as I am curious whether it's superfluous.
I have copied and pasted it under the templates ##Various Settings xcuserdata/
This is what I copied: /.xcodeproj/project.xcworkspace/ !/*.xcodeproj/project.xcworkspace/xcshareddata
/.xcodeproj/project.xcworkspace/xcshareddata/ !/*.xcodeproj/project.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings
/.playground/playground.xcworkspace/ !/*.playground/playground.xcworkspace/xcshareddata
/.playground/playground.xcworkspace/xcshareddata/ !/*.playground/playground.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings
Nope. .gitignore tells git which files (or patterns) it should ignore. It's usually used to avoid committing transient files from your working directory.
You can find an official gitignore example for Swift here. You can use it, by default ;)
