Avoiding primitive obsession in Swift
Avoiding primitive types such as Strings, Arrays, and Dictionaries in favor of objects and value types is definitely not a new concept. It really helps make your code readable, safe, and self-documenting of its intentions. But I haven't seen many articles introduce this concept in iOS programming, and Swift specifically. So if you're looking for great examples to power-up your architecture skills, make sure to read this and practice, practice, practice! It definitely doesn't feel natural at first.

Xcode Tricks: API Changes
Whoa! Super useful trick I didn't know about: In Xcode, select Help > API Changes. Thx @ericasadun!
Apple News
Swift 3.1 Released!
+1 to this one from @lorentey:
"Favorite Swift 3.1 feature not mentioned in the release notes: you can now define extensions for specific generic arguments 🌱"
Make sure to also check out some great code examples of the new changes here 🤓
Xcode 8.3 is now available
So excited 👏
"Autocompletion in breakpoint conditions!" - @zats
And the Mac no longer sleeps when a build is in progress 🥁 (via @NeoNacho)
But there are also some big bugs to keep in mind 😬
"Radar 31302382: Xcode 8.3 produces binaries 3x larger than Xcode 8.2 due to a 4x increase in bitcode http://www.openradar.me/31302382" - @simjp
"Found a huge Xcode 8.3 bug around entitlements files and variable substitution http://www.openradar.me/31383369" - @SmileyKeith
But by far my favorite feature is Xcode Stories 🤣

Vector Emoji
Super useful for those of you making an app with giant emojis 😜 But kidding aside, this can also serve as a useful template for making things like custom stickers and creating your own slight variation of the standard emoji set. Sketch coming soon!
What Bots Can Do, that websites and apps can’t
Agreed - bots that plan to do everything for everyone are horrible. Love the bot described here - it's something that is useful because it is very specialized for the task at hand. Apps could be made better if the bots built into them are this specialized.

What is your Ikigai?
A newsletter reader forwarded this to me last week, and for some reason, it really stuck with me as I woke up each morning last week.
"Your ikigai lies at the centre of those interconnecting circles. If you are lacking in one area, you are missing out on your life’s potential. Not only that, but you are missing out on your chance to live a long and happy life."

Swift's Pointy Bits: Unsafe Swift & Pointer Types
