How to resolve an XCode sandbox build error

A flower that represents Xcode with the text "Solve a<br />Sandbox build error" beneath it.

In the project's s settings, select the relevant target and under "Build Settings", set "User Script Sandboxing" to No.

An error similar to the one below may occur when running our starter project on Xcode 15+.

..error: Sandbox: cp(6282) deny(1) file-read-data ... (in target 'Starter Project' from project 'Starter Project')

cp: ./.scripts/pre-commit: Operation not permitted

To solve it, turn off User Script Sandboxing in the Build Settings of your project.
