title: RegEx in Swift?
body: <p>I am learning Swift, and I have (another) question. Are there regular espressions in Swift, and, if so, how do I use them?</p>
  
  <p>In my research, I found some conflicting information. <a href="https://developer.apple.com/library/prerelease/ios/documentation/Foundation/Reference/NSRegularExpression_Class/index.html">Apple Developer documents</a> has something mentioning RegEx, but it looks so different than any other language i've seen. If this is the solution, how do I use it?</p>
  
  <p><a href="http://benscheirman.com/2014/06/regex-in-swift/">This</a> website, on the other hand, suggests that RegEx doesn't exist in Swift. Is this correct?</p>
  
  <p>In case it helps, I am trying to use regex to get the average price of a bitcoin from JSON-style API that contains the price, but also a lot of stuff I don't want.</p>
  
  <p>Sorry for another basic question.</p>
