Font not working in iOS application

Hi,

I am having trouble exporting my font properly to make it work an iOS keyboard application. In the Android application the font was working fine immediately, but it wasn’t in iOS. A random part of the diacritic characters was not working on iOS, so I suspected that it might be because I did not build all diacritics from components. I thus rebuild the font that they are now all made up of components, but now it seems that the font does not export properly anymore at all. And I have no clue where the error lies…
It would be great if someone would be able to take a look at the font file to see what might be causing these errors.

I’m most sure if the keyboard has any special requirement. But did the font work in normal texts in iOS? I can take a look at the file. Send it to support at this domain.
