Writing your own Swift "if let"
I've understood the basics of how Optionals in Swift are implemented, but haven't thought much about the behind-the-scenes of "if let" 🤓

Build Tic Tac Toe with AI Using Swift
A super comprehensive and inspiring post on creating a Tic Tac Toe game using SpriteKit and GameplayKit. I admit that I never think I can create a game, but when I see how fun and challenging it is to make a simple Tic Tac Toe game, I always think I can make a simple game like that after all!
Hannibal #selector
A comprehensive look into how to use the new #selector keyword in different situations. One big take-away is that #selector doesn't include type information, so choosing between overloads that have the same argument list is very 😬

Xcode 8 beta 2 (8S162m) Now Available
Lots of stuff here, so make sure to read the Release Notes. I'm still wrapping my head around the new behavior of implicitly-unwrapped optionals in Swift 3, but hoping it'll just feel natural:
var x: Int! = nil // x is an implicitly-unwrapped optional value
of type Int?
var y = x // y is an ordinary optional value of type Int?
var z = x ?? 0 // x will be treated as an optional; since it is nil, z will be bound to 0
print(x + 0) // x will be implicitly unwrapped, causing a trap

Hopefully I'm not the only one who had to look up what Pokémon Go is 🙈 That's one way to gamify exercise, community, and crime...

Most of the talks from try! Swift Tokyo are out! Thanks @realm for doing all the video processing and putting it online. I know I wouldn't have otherwise had the resources to make this happen. I look forward to seeing you at try! Swift NYC, with a brand new lineup of speakers from our amazing community 🤓🌎💖

The Open World of Swift 3
Really clear overview of changes in Swift 3 - great explanation of what's going on with @noescape and curried functions, and some things I didn't really pay attention to such as how awesome it could be to use previously disallowed keywords as argument labels. The cool thing here is that this talk was done before WWDC, but of course with the openness of Swift, we already knew what was coming :)
SourceKit and You
I've never heard of SourceKit until Swift came out and it suddenly started crashing all the time. Well, apparently there is more to SourceKit than crashes & HUDs 😅 Love this talk explaining what SourceKit actually is and how to use it 💪

Learning
My Method For Prioritizing What To Learn
I've been a bit paralyzed by all the things I want to learn after WWDC on top of other things I want to learn that is unrelated, so I totally agree with @nerdonica here on having a system. I usually have lots of Google Docs instead of folders to sort out my information, but something more sophisticated is probably needed in my life as well:
"I’m embarassed over how complex my system is. But learning is one of the most important things we do as software developers and I want to be sure I’m focusing on the right things at the right time."
Swift Thoughts
It's now almost a month since WWDC, and I'm still feeling anxious and excited about all the new things and figuring out what I want to focus on next. I've been having lots of fun chatting with the try! Swift NYC speakers about the best topics for try! Swift in September, and I'm super excited to have the schedule finally up with so many different and exciting talks to learn from! Hope to see you there 🐥🗽🎉
