Clicking 'Export iOS' while on a different build target (like android) will result in an incomplete export.
The same might happen from the command line if -buildTarget iOS is omitted from the arguments.
This results in errors like
Value of type 'UnityAppController' has no member 'unityMessageHandler and
Value of type 'UnityAppController' has no member 'unitySceneLoadedHandler.
This issue is a sequel to #782, and might be a cause for issues like #426 #377 #486 #756 and more.
Problem
The build script will switch to iOS using SwitchActiveBuildTarget() and then continue the export.
However #if UNITY_IOS still returns false during this export, which ensures some code in XcodePostBuild will never be executed.
Unity needs a full recompile to change #if UNITY_ values, which can't happen within the same function.
Solution
I tried multiple approaches that wait for and detect a recompile, but none were reliable in all supported Unity versions.
In the end I decided to show a dialog requesting the user to run 'Export iOS' again, after the buildtarget has switched and scripts have been recompiled.
