Answer 1

Another reason for the error might be is that Xcode is running a script during the run phase.

If this is the case, you have 2 options:

1. Delete the script (makes sense if the script is NOT important)

2. Modify/update the scripts location path (Xcode might not be able to locate the script)

In my case, the script was important, so I modified/updated its location.

Originally, the script location path was written like this:

$SRCROOT/scripts/clean-assets.sh

Because the scripts path contained spaces (I moved the project to a new directory), I changed the path to this:

"$SRCROOT"/scripts/clean-assets.sh

By adding quotes to SRCROOT, changing it to "$SRCROOT", the error will go away.
