KeyPaths are a pretty popular Swift syntax!

But do you think you know all the features of KeyPaths? 🤨

Here are 5 things you (probably) didn't know about KeyPaths 🧵 Let’s start with #1️⃣: Whenever you use a method like `.map { }` or .filter { }`, you can pass it a KeyPath instead of a closure!

And the compiler will take care of automatically translating that KeyPath to a closure 👌

You’ve heard that actors are a very powerful feature of Swift, but you're not really sure how they work? 🤨

Don’t worry! I’ve got you covered! 😌

In just a few tweets we’ll go over everything you need to understand how to use an actor in Swift! 🧵 Let’s start with this class that implements a simple cache of images:

You’ve heard that async / await is amazing with asynchronous code, but you're not really sure how it works? 🤨

Don’t worry! I’ve got you covered! 😌

In just a few tweets we’ll go over everything you need to know to understand how this powerful tool works! 🧵 Let’s start by talking about functions!

In Swift there are two kind of functions.

First, we have the functions that don’t need to wait on anything to compute their results:

MVVM can feel a bit mysterious when you’ve never used it 😶‍🌫️

But I swear it’s really simple to understand! 😌

In just a few tweets we’ll go over everything you need to understand how this architecture works! 🧵 Let’s start with this ViewController.

If you think about it, this ViewController actually has a lot of responsibilities!

It must: fetch its data, format its data and then finally display its data 💪

My second talk at @iosconfsg on behalf of @worldlinexpert was all about how Swift KeyPaths can be leveraged to build some pretty effective syntax and patterns. Here's a thread that recaps some of the key ideas ⤵️ Swift 4 has introduced a new construct called KeyPaths, which allow to defer calls to the getter or setter of a property. They essentially perform the same job than a closure would, but with less $0 hanging around!

In a few hours I’m going to take-off ✈️ and head towards Singapore 🇸🇬 to attend @iosconfsg on behalf of @worldlinexpert 🤩
I plan on sharing pics 📸 and video 🎥 updates the whole time I’m away!
I’ll post everything right below this tweet ⤵️ First step of the trip: let’s ride the (very expensive 😱) shuttle, heading to the airport!
