// remove left buttons (in case you added some)
self.navigationItem.leftBarButtonItems = []

self.navigationItem.hidesBackButton = true

This is also found in the UINavigationController class documentation:
这也可以在 UINavigationController 类文档中找到：
navigationItem.hidesBackButton = true
回答by Harjeet Singh
navigationItem.hidesBackButton = true . put it in the viewDidLoadMethod
navigationItem.hidesBackButton = true 。把它放在 viewDidLoadMethod 中

Here is a version of the answer in
这是答案的一个版本
Swift 5
斯威夫特 5
您可以从故事板中使用它：// 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 }
}
}
Every navigation item of a view controller will have this new property in the top section of attributes inspector
视图控制器的每个导航项都将在属性检查器的顶部具有此新属性

That worked for me in Swift 5 like a charm, just add it to your viewDidLoad()
这在 Swift 5 中对我很有用，只需将它添加到您的 viewDidLoad()
self.navigationItem.setHidesBackButton(true, animated: true)

Go to attributes inspector and uncheck show Navigation Bar to hide back button.
转到属性检查器并取消选中显示导航栏以隐藏后退按钮。
