Yesterday, I filled a hole in the schedule with an impromptu session on visualization of mathematical functions. At the end I also showed how to submit the application to the Mac AppStore.
At the end I ran into an error saying "Invalid Binary" and I filled in the details for my contact information that it asked me for.
However, this didn’t solve the entire problem.
You also need to turn off Dynamic RTL and Run Time Packages. Unless you code sign them manually on the Mac side.
Finally, in order to bypass an issue with the Incremental Linker for Mac, you will need to turn off the Incremental Linker.
Doing these three things in addition gave me a successful submission to the AppStore.
