Swift proper way to load xib file

Question

I have some strange problem with loading xib file in swift project. It\'s so frustrating because I already know how to do it in Obj-C. But since swift is swift so you can\'t

Answer 1

I prefer to load from nib, by implementing loadFromNib() function in a protocol extension as follows:

(as explained here: https://stackoverflow.com/a/33424509/845027)

import UIKit

protocol UIViewLoading {}
extension UIView : UIViewLoading {}

extension UIViewLoading where Self : UIView {

  // note that this method returns an instance of type `Self`, rather than UIView
  static func loadFromNib() -> Self {
    let nibName = "\(self)".characters.split{$0 == "."}.map(String.init).last!
    let nib = UINib(nibName: nibName, bundle: nil)
    return nib.instantiateWithOwner(self, options: nil).first as! Self
  }

}
