custom view cannot be initialized

[derekshi]

I inherited my custom view from NibDesignable and it crashes on following lines: super.init(coder: aDecoder)

Could you reveal a bit more information? Maybe show some code?

Possible problems:

• Is your nib file named the same as your class.
• Is File's Owner set to your class
• Is the view placed in the nib a regular UIView, you must not use your custom class.

thank you. I resolved the issue as you guided. But NibDesignable seems not to be working on IB when I drag a new UIView into viewcontroller and set this UIView to my custom view class. On the identity inspector tab shows 'Designables Build Failed'. When I click on 'Show' button to the right, it just shows nothing. Not sure how to debug this. Any suggestions?

Does it work when you run your app?

Do you do any work in init(frame: CGRect) or init(coder aDecoder: NSCoder) ? Remember that IB will call init(frame: CGRect) and that init(coder aDecoder: NSCoder) will be called on runtime.

Also check your code in prepareForInterfaceBuilder(), a crash there will also give the error.

Ok, here is my custom view class:

class RestaurantSimpleView: NibDesignable {

@IBOutlet weak var resName: UILabel!
@IBOutlet weak var address: UILabel!
@IBOutlet weak var resPhone: UILabel!

let _nibName = "RestaurantSimpleView"

@IBInspectable var nameRes: String? {
    didSet {
        resName.text = nameRes
    }
}

override func nibName() -> String {
    return _nibName
}

var restaurant: Restaurant? {
    didSet {
        resName.text = restaurant!.name
        address.text = "\(restaurant!.street)\r\n\(restaurant!.city), \(restaurant!.state) \(restaurant!.zipcode)"
        resPhone.text = restaurant!.phone
    }
}

}

I don't necessary need the 'nameRes' variable. I just want to test it out. But doesn't seem to work.

Hi @derekshi I tried recreating your view and everything worked fine in Xcode 6.0.1
