I've uploaded two apps created with the MIT AI2 to the Google Play Store already - worked fine and I'm very happy with it. I am now just searching for options to also release an Apple version. What is the latest status here?
I couldn't find a definite answer from these threads:
MIT is still testing the Build compiler, necessary to produce the code the Apple store requires. Once the testing is finished, MIT still has to go through a procedure to obtain Apples permission.
Status: in progress
MIT has not provided a release date. A release might be in a few months or it might not be until the end of the year. When the compiled ios features are available and work as MIT intends, rest assured MIT will make an announcement.
For the moment, you cannot release a version of your app on thee Apple Store using App Inventor 2.
