Exposing Swift internal func to Objective-C file(in framework) without making it public

I have a Swift framework in which I have an Objective-C file. From that file I want to access a method which is declared as internal. I know that I can change it to public to make it available. But I don't want to expose it to the client app. Is there any way to achieve this?

In .swift:

@objc internal class func callBack(str: String) {
    print("Swift method was called | Passed value: " + str)
}

In .m:

- (void)callSwiftFunc {
    // This is not available, only if I set public in Swift
    [SwiftClass callBackWithStr:@"blabla"];
}
Solution

  • You can explicitly set the objc selector and then add a category which declares the method:

    replace @objc with @objc(callBackWithStr:), then simply add a forward declaration:

    @interface SwiftClass ()
+ (void)callBackWithStr:(NSString *)string;
@end
