iOS Dev Weekly – Issue 405 – May 24th 2019


Thanks for all of the wonderful support everyone gave the launch of iOS Dev Jobs last week. It was so lovely to see such a positive reaction from both the developer community, and the companies that are hiring. There are now 42 jobs listed there, up from 28 last week. What a great start to a new project. Thank you.

I didn’t mention it last week, but that launch also marked a personal milestone for me. Just over a year ago, I mentioned that I was going out on my own as an independent developer again. I had a pretty solid plan of what I was going to do, but almost immediately a very interesting freelance contract presented itself and I wanted to take it. That contract then got extended, but eventually came to an end about two weeks ago. As of right now, I’m not taking any other long term contract work and I’m happy to say I’m independent again. iOS Dev Jobs was the first of a few new projects I have planned. 🎉

What I’m looking forward to most though is getting back to making my own iOS apps again. I’ve nothing to announce yet on that front, but I can promise I won’t be as quiet in this coming year about what I’m working on as I have been in the past year! 📣

(Don’t Fear) The Reaper

A really interesting question we probably won’t have an answer to for years to come is whether UIKit is the ‘Carbon’ or the ‘Cocoa’ of this transition. I think the only appropriate answer is ‘yes’. UIKit is the present, and the developer ecosystem it will bring with it is incredibly important. AppKit is also the present, and it provides and powers the Mac as we know it.


Announcing Vapor Red Beta

Your options for hosting server side Swift with Vapor just got a little more flexible. Up until now, you were either completely on your own, or you were using the fully managed Vapor Cloud service. Vapor Red is easy Vapor hosting, but on your own cloud account, with much more flexibility around how everything runs. More serious options for server side Swift hosting are always good.

I hadn’t come across Gwendal Roué‘s SQLite wrapper for Swift until I saw the announcement of v4 this week. It allows any Swift struct (or class) to be mapped to a database record. It’s also well maintained, well documented and… how on earth did I miss it until now? 😀

Custom Navigation Transitions

Custom view controller transitions can make all the difference to how your app feels, but every time I think about implementing one I remember the pain of this API. 🤪 So, if you’re looking for the definitive guide on how to work with them, this four part (1, 2, 3, 4) series of posts from Bryan Clark is what you need.

Also, the app that these transitions are taken from, Locket is absolutely wonderful. I’ve been a customer for a while, and it’s an app that has never failed to make me smile when I open it. That’s pretty special.

Ordered Collection Diffing

Patrick Montalto (two issues in a row!) on the new Collection diffing API in Swift 5.1. This solves a very common requirement problem when building iOS apps, especially since we shouldn’t really ever be calling reloadData anymore.


While still functional, peppering UIActivityIndicator views all over your app can make it look a little old and jaded. Placeholder content shading is the new hotness, and placeholder content that shimmers is 🔥🔥🔥! Want it in a single line of code? Jogendra Kumar has what you need.


Animation handbook

Are you looking to advance your knowledge of animation in software? This free book from Ryan McLeod, maker of the wonderful BlackBox game looks great. I’m planning to give this a read from cover to cover this weekend.

Note: If you download it, just be careful of this dark pattern with the opt-in box as you enter your email address. It’s so disappointing to see this kind of trick being used. Just let me make a decision on whether I want to subscribe to your newsletter.

A Spectre Retrospective 

This three part article from Ben Sandofsky and Sebastiaan de With is (predictably) very worth your time. First up Ben talks about whether Spectre was going to be a feature in Halide or a standalone app. Sebastiaan then gives us a view on the design process and Ben finishes it up with a look at the technical challenges.
