Video Tutorial: Beginning Swift 2 Part 5: Optionals

Learn about optionals in Swift 2 and how you can safely unwrap them.


This is a companion discussion topic for the original entry at https://www.raywenderlich.com/3250-beginning-swift-2/lessons/6

Just one note here: at 4:54, it appears you made a mistake by saying “optional strings and strings are NOT different.” I think you meant to say “optional strings and strings are NOT the same.” Sounds like just a mistake.

Having said that, I am enjoying the series. I’ve never seen Swift so completely explained in syntax and use. I would recommend this video series to anyone over all the Swift books I have bought.
