Put it in the <code>viewDidLoad</code> method

just add it to your viewDidLoad()

Here is a version of the answer in <h2>Swift 5</h2> that you can use it from the storyboard:

<pre class="lang-swift prettyprint-override"><code>// MARK: - Hiding Back Button

extension UINavigationItem {

 /// A Boolean value that determines whether the back button is hidden.
 ///
 /// When set to `true`, the back button is hidden when this navigation item
 /// is the top item. This is true regardless of the value in the
 /// `leftItemsSupplementBackButton` property. When set to `false`, the back button
 /// is shown if it is still present. (It can be replaced by values in either
 /// the `leftBarButtonItem` or `leftBarButtonItems` properties.) The default value is `false`.
 @IBInspectable var hideBackButton: Bool {
 get { hidesBackButton }
 set { hidesBackButton = newValue }
 }
}
</code></pre>

Every navigation item of a view controller will have this new property in the top section of attributes inspector

In SwiftUI
.navigationBarBackButtonHidden(true)

Go to attributes inspector and uncheck show Navigation Bar to hide back button.

Right now I have two view controllers. My problem is I don't know how to hide the back button after transitioning to the second view controller. Most references that I found are in Objective-C. How do I code it in Swift?

<pre><code>[self.navigationItem setHidesBackButton:YES animated:YES];

现在我有两个视图控制器。我的问题是，在转换到第二个视图控制器后，我不知道如何隐藏后退按钮。我找到的大多数参考文献都在Objective-C中。如何在Swift中对其进行编码？在Objective-C中隐藏后退按钮代码[self.navigationItem setHidesBackButton:YES animated:YES];
