Changing the Height of the Navigation Bar iOS Swift

How can I change height of Navigation Bar - Swift 3

UPDATE 8/3/20: I posted this in 2016. A number of people have stated this no longer works so please use at your own risk. I am not working in iOS at the moment so I do not have an update handy. Best of luck!

Here is one way to do it:

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    let height: CGFloat = 50 //whatever height you want to add to the existing height
    let bounds = self.navigationController!.navigationBar.bounds
    self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)
    
}

How to change navigationBar height in iOS 11?

Your code is working fine and it´s nothing wrong with it. If you change the background color of your customNavigationBar you´ll see that you´ll get the navigation bar with the desired height. But it seems like it´s an issue with Xcode 9 to hide the default navigation bar.

Your code with:

Xcode 9
Sample Image

Xcode 8
Sample Image

As you can see in the Xcode 9 image, you have the custom navigation bar but the default one does not hide. Probably a bug in Xcode 9, I did not manage to hide it through the Storyboard either.

This seems to be a bug in Xcode 9, bug reports has been filed to Apple.

The hierarchy of UINavigationBar view is private so we can't manipulate it.We create our custom view and add into a Viewcontroller.

Cant change navigation bar height ios 11

Changing the height of the UINavigationBar is no longer directly supported in iOS 11 (see here, here & here).

The best you can hope for is to do something like having a view behind the navigation bar and removing the borders (see here for customisation examples).

Large navigation bar custom height

Ok, I found this way:

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.minimumLineHeight = 200
let attributes: [NSAttributedString.Key: Any] = [ .paragraphStyle: paragraphStyle]

let navigationBar = navigationController?.navigationBar
if #available(iOS 13, *) {
    if let appearance = navigationBar?.standardAppearance {
        appearance.largeTitleTextAttributes = attributes
        navigationBar?.standardAppearance = appearance
        navigationBar?.scrollEdgeAppearance = appearance
    }
} else {
    navigationBar?.largeTitleTextAttributes = attributes
}
