Swift - set delegate for singleton

Question

I have something like this:

class SocketManager {
    static let instance: SocketManager
    var socket = Socket()
}

extension SocketManager: SocketDelegate         


        

Answer 1

You set another class to conform to the SocketDelegate protocol and to set the delegate to that class. Once you do that, the SocketDelegate can call delegate methods which will be passed to the class that you set the delegate as.

Your classes will be like this:

class SocketManager {
    static let instance: SocketManager
    var socket = Socket()
    weak var delegate: SocketDelegate?
}

extension SocketManager: SocketDelegate {
    func someFunc() {
    }
}

protocol SocketDelegate: class {
    func someFunc()
}

class Socket: SocketDelegate { // so it conforms to the delegate
    SocketManager.instance.delegate = self
}
