The surprising awesomeness of Grouped Dictionaries
This is a Swift 4 feature I didn't know about, but one that could definitely come in handy!
let numbers = 1 ... 20
let predicate: (Int) -> Bool = { $0 % 2 == 0 }
let grouping = Dictionary(grouping: numbers, by: predicate)
print(grouping)
// [false: [1, 3, 5, 7, 9, 11, 13, 15, 17, 19],
// [true: [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]]

This is HUGE!!! As Apple adds more platforms and extensions and sizes and resolutions, it's becoming critical to have a scalable image format that doesn't lose quality as it sizes up 👏👏👏
Swift World: What’s new in iOS 11 — Vision
A deeper dive into the capabilities and code behind the Vision framework, including Machine Learning Image Analysis, Face detection, Face Landmarks Detection, Text Detection, Barcodes Detection, and Object Tracking. I didn't realize the Vision framework was this amazing and powerful!!
However, sometimes you might need other data besides vision. I love this creative project request for speech data!

Startup Swift
Fascinating story about a team using Swift in a startup environment, without knowing Swift well at first... The focus at first is on the product, and not as much on the code. Yet, Swift's focus on safety helped prevent crashes in code that was not that great.
Sometimes it's hard to remember that the most important part of our jobs is shipping! We learn in the process and improve naturally. We don't have to start out perfect.

3 Things Free Soloist Alex Honnold Teaches Us About Staying Hungry
Super inspiring story of a solo climber - someone who is the first to climb El Capitan with absolutely no help from other people and even harnesses, ropes or any other protective equipment that would save him from the certain death of a fall 😱
The key here is to break the big mountain into smaller challenges that you conquer over a long period of time. Oh, and when you reach the top, remember that there is another mountain to climb!

New rules following WWDC 2017 - App Store Review Guidelines History
Many changes here! Definitely scroll through at least. This one should allow a whole new category of powerful education and developer tools apps:
"Apps that provide a programming interface may now (in some cases) download and run code from the Internet."
Phased Releases in iTunes Connect
So easy! Seems like a no-brainer for bigger apps.
"It’s really simple to opt in, and because it’s all managed for you so long as you have no issues it’s all hands off. There’s a new radio button in iTunes Connect, Use phased release. If you select that, that’s it! 🎉"
Swift Thoughts
I'm still catching up and wrapping my head around everything that has been announced at WWDC. It really helped me to watch this video demo of all the new features in iOS 11!
