Most probably you meant callback, like

var multipleClouser: ((_ success: (Bool), _ failer: (Error?)) -> Void)?

and usage, like

multipleClouser?(true, nil)

or

multipleClouser?(false, SomeErrorHere)

set up like

multipleClouser = { success, error in
    if success {
        print("Done!")
    } else {
        print("Failure")
        if let error = error {
            print("\t with error: \(error)")
        }
    }
}
