Testing Swift code that uses system singletons in 3 easy steps

Unfortunately, as iOS developers, there is not escape from singletons... hi there our friendly singleton-based APIs UIApplication, NSDate, NSUserDefaults, URLSession, and many more.... But as Swift developers, we can abstract them out into protocols, hide them, and make an interface that is much safer to use 🙌

Detecting the first launch of the iOS application — the wrong and the right way

Detecting the first launch of my app is always something I copy from StackOverflow and don't think about much after that. But this post definitely has some great refactoring to the StackOverflow version, including making it easily testable and isolating responsibilities 👍

50 iOS Interview Questions And Answers Part 2

Good list of questions to get started with if your team is stuck with white-board algorithm interview questions 🤦🏻‍♀️... For those not involved in the interview process currently, this is also a good reference and review of some key iOS and Swift concepts. Also check out Part 1 and Part 3.

Okinawa Island - The Healthiest Place on Earth

The secret to a happy and healthy long life 🤔

The Okinawans’ secret, I’ve come to understand, lies in two things – their food, and their attitude towards life. As a happy bunch of people, the elders seem to have no worry etched on their faces, stress seems to be a foreign concept to them. An 88-year-old farmer who still works 11-hour days at the field, says, “I hardly ever get angry. I enjoy life because I’m happy at work and I think that’s the medicine for a long life.”

In Case You Missed It

This week, I've been working on a big refactor to the try! Swift Data Framework now that the Tokyo conference is over and I can repay some technical debt. Still a lot of work to do, but here are some things I ran into:

Everything You Ever Wanted To Know About Sequence and Collection

"Everything is built on top of a protocol called Sequence. Sequence provides the backbone of many of the things that you’re used to working with when you work with arrays. For example, when you use map or filter, when you find the first element passing some test on Sequence, that is all defined on this protocol called Sequence. It’s the simplest thing, and everything is built on top of Sequence. The rest of the protocols layer on top of each other like a ladder. We’re going to work our way through part of that ladder."

Swift Releases Have Themes

Good insight into how the Core Team decides which proposals should make into the next version of the language. The key is that each release focuses on a small number of themes - proposals contributing to theses themes are given priority:

"The coherent design is important both within the release—because it makes it easier for developers to learn to use the new features together—but also for the long-term health of the language. Without theming proposals, it is very difficult to see how an individual proposal fits into the overall direction of Swift."

SE-0158 [ IMPLEMENTED (Swift 4)]: Package Manager Manifest API Redesign

Thanks @aciidb0mb3r 🚀

The Package.swift manifest APIs were designed prior to the API Design Guidelines, and their design was not reviewed by the evolution process. Additionally, there are several small areas which can be cleaned up to make the overall API more "Swifty".

Apple Acquires Workflow

Possible future of iOS? I've been talking a lot about how the future is a more decentralized version of your app, and it definitely looks like Apple is heading this way especially now with the acquisition of Workflow. But of course it could just be a longer-term acquihire of a very talented team. Congratulations to everyone involved 🎉

WWDC ticket registration opens today! I won't be attending this year, even just being in the city for AltConf, but I've had an amazing time every time I have attended. I'm sure it's going to be amazing... even in San Jose!
