How to open a URL in Safari in Swift (使用URL打开Safari)

Swift version: 5.4

If you want the user to exit your app and show a website in Safari, it's just one line of code in Swift. I'll make it three here because I'll create the URL in the code too, then safely unwrap it:

if let url = URL(string: "https://www.hackingwithswift.com") {
    UIApplication.shared.open(url)
}

It's worth adding that you have the option of using SFSafariViewController inside your app, which recreates the entire Safari experience right inside your app.
