Hi, el! Thank you for so much help. I'm sorry for the delay. I have made an attempt to simplify the framework code I borrowed from your project. I removed FreSwift lib. Just one Swift class that prints a text to console. According to your advice I have set "Provisioning Profile" to none. Application identifier has always been added to the manifest. It is ok. The distribution provisioning profile is absolute and has no asterisk. Everything (Swift framework, ANE and AIR project) builds fine. But when I'm launching the app, I get the following crash. This is where I'm stuck. I have just upgraded to XCode 10 and Swift 4.2 Probably this is the cause of the crash. I wonder if you can help.
