I am downloading the UnitySetup-iOS-Support-for-Editor-2019.3.0a5.pkg file as wished by the Unity app under “Open Download Page” in build settings, but when I go through the download seems to be going fine but then it gives me “The Installation Failed: The installer encountered an error that caused the installation to fail. contact the software manager for assistance.” This is obviously super vague so I have no clue whats going on - please help.
If you are unfamiliar with Unity I might not recommend an Alpha version as you are attempting. Better to go with a released version, like 2019.1 or 2018. The lowercase “a” is the clue here in the pkg name. You’ll want to look for a release with an “f” instead
