[swift5] How to transition from the app to an external site by specifying the URL

Posting points

This time, we will introduce the function to transition from the application under development to the developer's SNS and homepage.

Implementation code


// url =Specify the URL of the site you want to transition to as a String type
let url = NSURL(string: "")

if UIApplication.shared.canOpenURL(url! as URL) {
  UIApplication.shared.open(url! as URL, options: [:], completionHandler: nil)

This is OK! If you tap the button or Cell of TableView to make a transition, it will be simple and easy for the user to understand intuitively.
