Building URLs With NSURLComponents

Wed, 04 Sep 2019 07:00:00 -0400

If you have been programming for Apple platforms for a while, chances are you have seen (or maybe even wrote yourself) a line of code that looks like this:

let url = URL(string: "https://www.google.com/search?hl=en&q=pullip")!

Whether you wrote it yourself or someone else did it, one thing is clear: This is not a safe way to build URLs. Can you know, for sure, that your URL is actually valid? Intuitively, all of us can see a URL and see if it’s valid, but there is a whole lot of governing in the URL format that at some point we may find funny URLs that look valid and aren’t, or the other way around; they look invalid, but aren’t.
