As the lastest Harman AIR SDK should resolved the code-signing issues for iOS 15, I followed those steps to be able to build an IPA :
- I have overlaid my Flex SDK 4.16.1 - AIR31 with the Harman AIR SDK 33.1
- I have forced my 32-bits Flash Builder 4.6 to use a 1.8 JRE (also 32-bits) (with -vm in the FlashBuilder.ini)
- When I launched one of my Flex projects with the Flash Builder Simulator, I could see the Harman's splashscreen
- Then I built an IPA and pushed it on my iPad with iOS 15 but I still have the message from Apple asking to use the latest code signature Format
Did I miss something ?
