iOS app with custom ANE doesn't load past Air version 27

Hi.

I have a custom ANE that I use in an Air iOS project.

My app runs fine if I compile it with Air version 27.

If I try to use the 28 or 29 SDK my app just stays on the initial splash screen. It doesn't even connect to the debugger.

I pin pointed the problem to my custom ANE. If I remove the ANE from the project I can use the SDK 28 and 29 without any issues.

I tried compiling the ANE with ADT from the SDK 29 but I'm still facing the same issue. Definitely something changed in Air 28 that prevents my ANE from loading. The ANE is coded in Objective-C and uses the Healthkit framework.

Does anyone know what I need to do to make the ANE work in AIR 28 and 29?

Thanks in advance.
