Ambiguous reference when using selectors

Question

Ready example for testing on playgrounds:

import Foundation

class Demo {

    let selector = #selector(someFunc(_:))

    func someFunc(_ word: String) {
        // Do something
    }

    func someFunc(_ number: Int) {
        // Do something
    }

}

I get an error Ambiguous use of 'someFunc'.

I tried this answer and got something like:

let selector = #selector(someFunc(_:) as (String) -> Void)

But still get the same result.

Any clues on how to solve this?

Answer 1

Short answer: this is not possible.

Long explanation: if you want to use #selector, the methods must be subjective Objective-C, so your code will look like this:

@objc func someFunc(_ word: String) {
    // Do something
}

@objc func someFunc(_ number: Int) {
    // Do something
}

Thanks to the annotation, @objcthey are now exposed to Objective-C and a consistent tone is created. Objective-C can use it to call Swift methods.
