iOS Swift 5 Tutorial: Superview and Subviews in iOS Hindi 2020.

When my app gets back to its root view controller, in the viewDidAppear: method I need to remove all subviews. How can I do this?

In Swift you can use a functional approach like this:

view.subviews.forEach { $0.removeFromSuperview() }

As a comparison, the imperative approach would look like this:

for subview in view.subviews {    subview.removeFromSuperview() }

These code snippets only work in iOS / tvOS though, things are a little different on macOS.
