无法获取URL的内容

Question

So I have the following URL:

let theURL : NSURL = NSURL(string: "http://www.iana.org/domains/example")!

But all I get after running:

let blob : String
do {
    blob = try String(contentsOfURL: theURL)
}
catch {...}

Is a console statement that reads as follows:

CFURLCopyResourcePropertyForKey failed because it was passed an URL which has no scheme

The URL is valid, and the code works with:

http://www.example.com

What am I doing wrong?

Answer 1

Here's a cleaner version of what you're trying to do.

let theURL = NSURL(string: "http://www.iana.org/domains/example")!

let blob : String

do {
  blob = String(theURL)
}
catch { }

Corrections:

1. theURL is an optional that was still wrapped that's why you couldn't assign it.
2. You misused contentsOfURL
3. If you're immediately assigning the variable you don't need to declare it the way you did

I'm not sure what you're trying to accomplish, but if you provide me with more information I can better answer your question.
