NSURLConnection initWithRequest is deprecated

Question

I am adopting the Gmail API in iOS and I am getting the warning:

initWithRequest is deprecated

in the followin

Answer 1

It seems that the whole NSURLConnection API has been deprecated in iOS 9. Existing apps will continue to work, but new builds (linked against iOS SDK) must use the newer NSURLSession API.

Ray Wenderlich has a good tutorial here. Also, of course, check the official documentation.
