How to call Swift function with more than one parameter from Objective C class?

Question

For example I have this method in swift:

@objc class MyClass: NSObject
....
@objc class func viewWithIndex(index: Int, str: String) {
    println(index, str)
}

then i wanna call that method in my objective-c class, and i was expecting as simple as this call [MyClass viewWithIndex:10 str:@"string"]; but it doesn't work.

How do i call it? Please help.

Note: I have already a working swift function call to objective-c [MyClass showSomething]; so that means i have successfully setup necessary settings to bridge classes. Only the function that has two of more parameters is my problem. :)

Solved:

I dont know what i happened but i just restarted my mac and removed objc and it worked with the call [MyClass viewWithIndex:10 str:@"string"];. I remember reading in documentation.

Migrating Your Objective-C Code to Swift

• To be accessible and usable in Objective-C, a Swift class must be a descendant of an Objective-C class or it must be marked @objc.

Answer 1

This worked for me in Swift 3.0

public class func viewWithIndex(_ index: Int, str: String) {
    println(index, str)
}

Adding the underscore before the first parameter in the Swift declaration allowed me to call from objective c without naming the first parameter, like this:

[MyClass viewWithIndex:10 str:@"string"]
