My application does not load on IOS 15 beta2 release. While debugging it on the Xcode13 beta2, got that Objc returns 28 properties for NSParagraphStyle. While enumerating through those properties when my code tried to set values for one of the key ”superclass”, it crashes with below exception.
“'NSUnknownKeyException', reason: '[<NSMutableParagraphStyle 0x6000018a6ca0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key superclass.'”
However same code works fine for xcode 12 where ObjC returns 17 properties for the NSParagraphStyle.
