Xcode 6界面构建器不显示自定义类

Question

I have an error in my Xcode 6.3 interface builder. When i create a new custom class and want to add it to interface builder custom class field. It is not available. I do use Swift as languag.

What I tried:

• delete derived data
• reinstall Xcode
• cleand project
• created new project
• Class name is same as file name
• Superclass and interface builder class are the same

Nothing worked out ;-( Any idea what it could be ?

Answer 1

I had the same issue and thought it as a bug. But it was my misunderstanding.

What actually happens is:

Custom Class drop down list shows only those custom classes which are subclasses of currently selected object's class.

For example, if we have imageview object in xib and after selecting it, when we see custom class drop down list, it'll show only custom classes inherited from (subclass of) UIImageView.

What I was doing wrong was looking for those custom classses which are subclasses of UIView.

In your case, it might be, not 100% sure, happening due to your TimerCVC is a subclass of UICollectionViewController instead of UIViewController.

Answer 2

TimerCVC is not a subclass of UIViewController

Press ctrl-n -> on the left panel choose iOS ->Source -> Cocoa Touch Class -> from the dropdown menu choose UIViewController -> And then fill the name field (automatically Xcode autocomplete with ViewController on the end).

It should look like this

import UIKit

class TimerViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}
