Swift Developments is a hand-curated newsletter containing a weekly selection of the best links, videos, tools and tutorials for people interested in designing and developing their own apps using Swift.
Some great news this week with Apple rolling out a new feature in TestFlight that lets developers invite testers via a public URL. It gives you all the features you would expect like the ability to limit the number of signups and the ability to disable the public link at any time and overall looks like a great step forwards.
Swift 5 Release Process
With Swift 4.2 out of the door, the Swift.org team have been turning their attention to Swift 5. This week, they’ve published details and an estimated schedule for the release along with details of the main motivations and goals for the release.
A great article on the Swift.org blog this week from @mikeash in which he looks at how the Swift runtime’s
Mirror API works. I really enjoy these types of article and find that they are a great way to get acquainted with the interals of the Swift language. More please! ?
You’ll most likely be familiar with the picture-in-picture functional of FaceTime calls where the picture gravitates toward one corner of the screen but do you know how it’s implemented? @jordanmorgan10 takes a look at UIKit’s
UIFieldBehaviour class, the class that’s providing the magic behind the scenes.
It’s fair to say that Apple’s
UIAppearance APIs aren’t always the most flexible way of implementing different themes for your app but with a little perseverance and with the power of Swift protocols you can construct something that does provide the structure and flexibility that you need. @basememara shows you how.
@johnsundell continues his weekly series with some useful tips on how to clean up your asynchronous unit tests by implementing your own simple async / await approach. Hopefully some day Swift will have this natively but until then, John has you covered.
I know I linked to this last week but since then, the team at NSSpain have release a bunch of new videos from this years conference with some great talks from the likes of @dimsumthinking, @stephencelis, @allonsykraken, @krstnfx, @davedelong and more. Definitely worth a look (or even a second look ?) if you haven’t already.
I wasn’t sure what to make of this tweet from @olebegemann this week except ‘wow’. I’d never have thought that it was that complicated! The Find My Friends data model (courtesy of @_inside) doesn’t look any simpler either!
