Swift Set View Z Order Front

As a programmer, it is essential to know how to manipulate the order of views in your app's user interface. In Swift, you can use the bringSubviewToFront() method to bring a specific view to the front of the view hierarchy.

Syntax
func bringSubviewToFront(_ view: UIView)

This method takes a single argument: the view you want to bring to the front of the view hierarchy.

Example

Suppose you have a UIView called myView that is currently obscured by other views in the hierarchy. To bring myView to the front, you can use the following code:

view.bringSubviewToFront(myView)

This code will move myView to the top of the view hierarchy, making it visible above other views that were previously obscuring it.

Conclusion

Manipulating the Z order of views in your app's user interface is an essential skill for any iOS developer. With the bringSubviewToFront() method in Swift, you can easily move views to the front of the hierarchy, ensuring that they are visible to the user. Remember to use this method selectively and with caution, as rearranging views can have unintended consequences on the layout of your app.
