    I just trying to make a IOS build and it failed with
    'The Assembly UnityEditor is referenced by UnityEngine.UI ('D:/ProgramFile/Unitys/2018.4.24f1/Editor/Data/UnityExtensions/Unity/GUISystem/UnityEngine.UI.dll'). But the dll is not allowed to be included or could not be found.'
    'Trying to add file D:/svnlocal/unitywindows2018releaseIOS/Temp/StagingArea/Data/Managed/UnityEngine.UI.dll to the list of ouptut files in the build report, but a file at that path has already been added.'
    Did anyone meet this before?
