Version 7.3. Hi All, I'm finding it very difficult to follow along with my version of Xcode 7.3
The tutorial version of Xcode has so many differences to it than the current version of 7.3. that I am struggling to even follow along in the videos. For example, the Swift Functions and Optionals video uses a culprit.toInt() which no longer exists and makes the whole video impossible to follow along with. I've searched other ways to initialise strings to integers, but can figure out in this case where to place this code.

Hey James Killeen,
This is because of the update from Swift 1 to Swift 2.2. We are currently at Swift version 2.2. I recommend switching to the Swift 2 track. This is the latest Swift content on Treehouse. Theres a course on optionals there that will be easier to follow because of the updated syntax.
