I have an @State private var set up to hold a string:

@State private var siteLink = ""

This is bound to a TextField like so:

TextField("Site Link", text: $siteLink)
    .keyboardType(.URL)
    .textContentType(.URL)

And I have a button like so:

Button(action: {
    openURL(URL(string: simpleLink)!)
}) {
    Image(systemName: "arrow.right.circle.fill")
}
.disabled(siteLink == "")

I'm trying to make things simple for the user with data entry, and so I have this code to ensure that even if the user enters something simple like "www.apple.com" or simply "apple.com" when they tap on my button it will still work. So I did the following:

var simpleLink: String {
    if !siteLink.contains("http") {
        return "http://\(siteLink)"
    } else {
        return siteLink
    }
}

That seems to work fine. If the user enters a full URL it will take them there, but if they simply type a shorter version it still works. I'm just curious if this is the best way to do this or if anyone has any better ideas or if Apple has some built-in way to handle this in SwiftUI that I missed.
