Unable to access Swift 4 class from Objective-C: “Property not found on object of type”

Question

Using the latest Xcode 9 beta, I\'m seemingly completely unable to access properties on Swift classes. Even odder, I can access the class itself to instantiate it or whateve

Answer 1

I also encountered with this problem in swift 3.0

class declaration was like that

class ClassA {
//statements
}

above class was not accessible in Objective C code and it was also not registered in -Swift.h

once I inherited from NSObject like this:

class ClassA : NSObject {
//statements
} 

the class was accessible in Objective c and got registered with -Swift.h

This solution is useful when you don't want to avoid inheritance from NSobject class.
