How to implement the below objective-c init method in swift

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil withName:(NSString *)name {
    if (self = [self initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
        self.name = name;
        self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bg.png"]];
    }

The equivalent would be this:

override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?, name:String!)
{
      self.init(nibName: nibNameOrNil, bundle: nibBundleOrNil);

        self.name = name;
        self.view.backgroundColor = UIColor(patternImage: UIImage(named: "bg.png"));
}

You may have to implement required initializers if you get an error, but should not be needed if you use a later version than Beta5:

required init(coder aDecoder: NSCoder!) {
    super.init(coder: aDecoder)
}

where the sending of "name" parameter

Daniel Klöck Over a year ago

Sorry, forgot that one. I added a it as parameter. But, as in ObjC, now it is not a standard initializer anymore.

then how to call this method from a another viewController. I mean how to pass data from one controller to another controller.

Daniel Klöck Over a year ago

Same way as you would do it in ObjC, you define the function in your header and use it instead of the standard initializers.
