How to Hide Navigation Title in Swift: A Step-by-Step Guide

The Problem with Navigation Titles

In Swift, the navigation title is typically set using the `title` property of the `UINavigationItem` class. However, this approach has its drawbacks. For one, it can be tricky to customize the title’s appearance, and two, it can take up a lot of space. That’s why we’ll be exploring alternative solutions to hide the navigation title altogether.

Method 1: Using the `titleView` Property

One way to hide the navigation title is by setting the `titleView` property to a `UIView` with a zero-width constraint. This will effectively hide the title, while still allowing you to customize the navigation bar’s appearance.

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Create a new UIView with a zero-width constraint
        let titleView = UIView()
        titleView.frame = CGRect(x: 0, y: 0, width: 0, height: 44)
        
        // Set the titleView property
        navigationItem.titleView = titleView
    }
}

This method is simple and effective, but it does have one drawback: it can cause issues with accessibility, since the title is no longer readable by screen readers.

Method 2: Using a Custom `UINavigationItem`

Another way to hide the navigation title is by creating a custom `UINavigationItem` subclass, and overriding the `title` property. This approach allows you to still set a title for your view controller, while hiding it from view.

import UIKit

class CustomNavigationItem: UINavigationItem {
    override var title: String? {
        get {
            return nil
        }
        set {
            super.title = newValue
        }
    }
}

To use this custom class, simply create an instance and assign it to your view controller’s `navigationItem` property:

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Create a custom navigation item
        let navigationItem = CustomNavigationItem(title: "My Title")
        
        // Assign it to the view controller
        self.navigationItem = navigationItem
    }
}

Method 3: Using a Fake `UINavigationItem`

Our final method involves creating a fake `UINavigationItem` instance, and setting its `title` property to an empty string. This approach is a bit more hacky, but it gets the job done.

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Create a fake navigation item
        let fakeNavigationItem = UINavigationItem(title: "")
        
        // Set the fake title
        navigationItem.titleView = fakeNavigationItem
    }
}

This method has one major advantage: it’s extremely easy to implement. However, it can cause issues with other navigation bar elements, such as the back button.
