Trouble: 'PrincipalViewController' does not have a member named 'revealViewController' in swift

Question

I am working on a creating a sidebar menu using SWRevealViewController in Swift. Trouble is I get the following error: 'PrincipalViewController' does not have a member named 'revealViewController'

The code I am working on is:

class PrincipalViewController: UIViewController {
@IBOutlet weak var menuButton:UIBarButtonItem!

override func viewDidLoad() {
    super.viewDidLoad()

    // This is the line with the error
    if self.revealViewController() != nil {

        menuButton.target = self.revealViewController()
        menuButton.action = "revealToggle:"
        self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())

        // Uncomment to change the width of menu
        //self.revealViewController().rearViewRevealWidth = 62
    }

}

Any ideas? Thanks a lot

What is self.revealViewController()? – Memphian

I think is the view controller for the side bar. But I did a search in the demo app that is working and there is no reference to that view – Immorality

This is the site where I downloaded the code (appcoda.com/sidebar-menu-swift) – Immorality

So why are you using () after the property? – Memphian

I just found the problem. There is son objective-c code in the app, and the bridging header was not well configured. Thanks a lot

As of Cocoapods >0.36, if you're using Cocoapods to add SWRevealViewController to your project, don't mess with the bridging header. Just uncomment use_frameworks! in your Podfile. Then import SWRevealViewController into your ViewController.swift file. Here's a great article that explains it.

To clear this up for others who do not understand the answer's explanation... Make sure the Bridging header file is connected to the Path of the Objective C Bridging Header which is found in the Swift Compiler found in Build Settings of your project...

Here is a link for the way to check if it is there, look under adding it manually for a picture as well...
