Call a Swift Singleton from Objective-C

Question

I\'m having some trouble accessing a Swift Singleton from Objective-C.

@objc class SingletonTest: NSObject {

    // swiftSharedInstance is not accessible fr         


        

Answer 1

Swift 5 and above

final class Singleton: NSObject {

    @objc static let shared = Singleton()

    @objc var string: String = "Hello World"

    private override init() {}   
}

use in Objective-C

NSLog("Singleton String = %@", [Singleton shared].string]);
