Swift closure using firebase blocks compile

Question

I'm following an online class (from December, 2016) and am getting the error in this screenshot.

Here's my code: // // FirebaseManager.swift

import UIKit
import Firebase
import FirebaseDatabase
import FirebaseAuth
import FirebaseAnalytics

class FirebaseManager: NSObject {
    static let databaseRef = FIRDatabase.database().reference()
    static var currentUserId:String = ""
    static var currentUser:FIRUser? = nil

    static func Login(email:String, password:String, completion: @escaping (_ success:Bool) ->
        Void) {
        FIRAuth.auth()?.signIn(withEmail: email, password: password, completion: { (user,error)
            in
        if let error = error {
            print(error.localizedDescription)
            completion(false)
        } else {
            curentUser = user
            currentUserId = (user?.uid)!
            completion(true)}
        })
    }
}

And here is the screenshot of the code from this example:

I've reviewed a few SO questions including this one but don't see an answer that applies to my situation. Please see my attachedmy swift version settings swift settings. Attaching again as I don't see it.

Thanks for your help

try removing _ success from completion & just type `completion: @escaping (Bool) -> Void)` — aashish tamsya, May 16 '17 at 11:18
That didn't seem to help. Can you explain the reason for your recommendation? Thanks — Jazzmine, May 16 '17 at 12:39

Why are you using legacy Swift instead of Swift 3? The sample code you show is for Swift 3. The @escaping attribute was introduced in Swift 3, so that could explain the build error.
