Unrecognized Selector NotificationCenter Swift 3

I've read all of the possible solutions on stack overflow but not one works for me.

My code is

func foo() {
    NotificationCenter.default.addObserver(self, selector: #selector(fetchedUser(notification:)) , name: NSNotification.Name.init("dbReady"), object: nil)
    loggedUser.fetchUserByUID(id: current.uid)    
    return true
}

func fetchedUser(notification:NSNotification){
    let info = notification.object as! [String : AnyObject]
    print(info)
}

And in another class I've:

 NotificationCenter.default.post(name: NSNotification.Name.init("dbReady"), object: dictionary)

All of syntax for selector doesn't work

I tried: 

1. fetchedUser
2. fetchedUser:
3. fetchedUser(notification:)
4. "fetchedUser:"

And other ten options maybe. Can anyone help me?

Solution

  • My error was a selector with name didn't exist "fetchedUserWithNotification:". I solved my problem by rewriting a new class and copy and paste all its content. Maybe it was a Xcode bug (IMHO the last version is plenty of it )
