I recently deleted the Twitter app, but I still wanted the posting and messaging functionality. So I downloaded other apps for just those purposes. The big app I now use for posting is Buffer - and I'm really impressed by their use of Haptic Feedback when I send a tweet. I haven't used haptic feedback much or felt many apps use it - but it clearly stands out and reassures me that my tweet has in fact been sent even if it doesn't go off the screen right away. I encourage you to play with it in your own app!

Modelling state in Swift
Good tips on how to deal with State in a Swift-y way!
"While there are no silver bullets when it comes to state handling, modelling your state in a way that removes ambiguity and enforces clearly defined states will usually lead to more robust code."
"Reducers are a way to deal with state changes, and are great for dealing with asynchronous code."
Follow the refactoring in this blog post to try to understand what a reducer is. Either way, it seems like a super helpful pattern for testing code that seems untestable. Might take a few times to fully get it.

Faster Logins With Password AutoFill in iOS 11
"You can also tell iOS the website with which your app is associated. If the keychain contains credentials saved from Safari on iOS or macOS, those credentials will be suggested—eliminating the hassle of manually searching them in the keychain.
If you're using Universal Links already, your app should show the credentials for your website in the QuickType bar. iOS knows which website is associated with your app, so it is 100% ready to suggest credentials.
Another way to strongly link your app and website together, without needing Universal Links, is a web credentials associated domain service. "

The Easiest Way to Get a URL for your Apple Wallet Passkit Pass
For try! Swift NYC, we are playing with the idea of adding QR codes to conference badges that will add attendee’s contact information business card to your Wallet app. It is easy to generate a QR code from a URL. And it is relatively easy to create a PassKit Pass – it’s basically just a bunch of files in a folder. But I was super confused on that step in-between – how do I create a link from the final Passkit
