My post was in January. Recently MIT released a buggy version of Companion for iOS. Not all code that works in Android works with iOS yet. Projects that use Android extensions do not work with iOS at all. 
You are simultaneously posting in two places about essentially the same issue ( aiStarter update MIT AI2 Companion2 to 2.58au) Doing this causes confusion.
Since BlueStacks is working for you; it appears your issue is problems with aiStarter.
