I’ve started using Unity 2021.3.2f1, but had the following xCode error after building for iOS:
/Build/MapFileParser.sh: No such file or directory
To solve this I copied MapFileParser.sh into the build folder from one of my Unity 2020 installs (e.g. C:\Program Files\Unity\Hub\Editor\2020.3.34f1\Editor\Data\PlaybackEngines\iOSSupport\Trampoline), and was able to deploy to my device.
