GeneDeLisaDev: #Xcode 9.2 is available. I had to free up 18GB to download it. See where it says 5.5 GB? ha! With any luck, I'll be able to run on my #iOS 11.2 device now. pic.twitter.com/tYhRE7BdMv

ios 11.2 대응 Xcode 9.2 업데이트

After 4 years of internal usage, Twitter has decided to share with the community their own Network Layer framework on top of Apple's NSURLSession.

- Additional flexibility and scalability
- Ability to specify the execution mode
- Prioritization of requests
- Dynamic retrying with retry policies
... (so so on)

p.s. it's time to rewrite it to Swift :)

Ash Furrow prepared an article about Snapshot Testing - talks about their experience at Artsy, pros/cons of this methodology, so how valuable this to use it.

A bit poor with good articles lately, thus there's a delay in the channel. 🙁

Nathan, inspired by “Designing Fluid Interfaces” WWDC session, has written a great article that demonstrates how to achieve these effects. The article covers not only a theory part but also you will see eight examples (some of them are part of iOS os) with visual animations, critical code, and important remarks.

”An interface is fluid when it behaves according to the way people think, not the way machines think.”

Share this knowledge with your designers, because this makes the user interface more comfortable, enjoyable. They have to know about it!

Let's talk a bit about the architecture.

Alexander tells his thoughts about this topic - what architecture we used to prefer in the past, what is a popular architecture nowadays and what we can come to. MVVM, MVC, and MVP are so known for us of course, so the Elm Architecture has to be the most interesting to read.

p.s. I highly recommend reading the "App Architecture" book to cover all these architectures more deeply.

Oh, I so adore articles dedicated to the scroll optimization and this one isn't an exception. Even though this article was written in the distance 2015, there are a lot of techniques that are still actual nowadays. Especially I like the tip about Subpixel Rendering.

p.s. Don't be afraid of Objective-С.

There's an awesome tool I've found.

”It injects itself into the iOS Simulator so that it can monitor views and adjust them in real time.”
