I coded in a button in xcode's viewcontroller.swift - How do I get it to show in storyboard?
<p>Specifically, I coded in facebook's login button into my view controller file.  However it does not show up in storyboard.  I know how to make a button in storyboard and then connect in code with right click drag, but when I try this to back into connecting the two and create my IBOutlet, I seem to just be creating two different login buttons.</p>

<p>How do I get the facebook login button to show up in storyboard?</p>

<pre><code>import UIKit
import FBSDKCoreKit
import FBSDKLoginKit

class ViewController: UIViewController, FBSDKLoginButtonDelegate
{    
    override func viewDidLoad() {
        super.viewDidLoad()

        if (FBSDKAccessToken.currentAccessToken() == nil)
        {
            print("Not logged in..")
        }
        else
        {
            print("Logged in..")
        }

        let loginButton = FBSDKLoginButton()
        loginButton.readPermissions = ["public_profile", "email", "user_friends"]
        loginButton.center = self.view.center
        loginButton.delegate = self
        self.view.addSubview(loginButton)
    }
</code></pre>
