The problem happens when files in your target are marked read-only. One common cause is a copy-files script where the files it is copying are read-only.

You can try adding a chmod u+w command to the script to ensure the files are read-write after being copied into the target.

For Cocoapods, you can try chmod -R u+w /path/to/your/project/Pods to make all files in the pods subdirectory writable.
