Can't convert value of type URLSessionConfiguration to URLSession

Hey,

I'm trying to connect my app to a database using a tutorial from codewithchris.com Unfortunately, the code there is written in Swift 2, so there are a few errors.

    var session: URLSession!

    let configuration = URLSessionConfiguration.default

    session = URLSession(session: configuration, dataTask: self, didReceiveData: nil)

I'm trying to get this running but it shows up this error at session = URLSession(...)

"Cannot convert value of type URLSessionConfiguration to expected argument type URLSession"

It'd be very great if someone could help me out!

Thanks,

Bruce.

I could be wrong, but if I could remember whenever you type in Swift 2 code it should automatically correct the syntax, or it's in a menu somewhere. I know that when I had all my Swift files (made before Swift 3 and they were all in Swift 2) it just automatically converted them for me into Swift 3 syntax.

I hope this helps!

Yes it autocorrected but the error came after the correction.
