@TheHmmka thank you for reaching us.
How do you integrate PubNub framework with your product? Is it compiled once in some environment and added as a linked framework into the project?

With CocoaPods. I didn't test with SPM.

Did you try to clean all targets (including those built by Cocoapods) and re-build from the scratch only for iOS 15? That method is added during source code compilation to work with generics, and looks like it is missing in iOS 15 - this possible only if lib has been built for iOS 16+ and then used with iOS 15 code.

Here is the Swift language issue regarding this exception.

I'll try a little bit late, thanks for your support!
