Preparing for the unexpected.

This week I've been working hard on adding macOS support to our internal SDK at WeTransfer. Our SDK contains about ~20 packages, ranging from UI and Foundational focused logic.

Our decision to develop modularly using Swift Package Manager pays off during this transition. In a few days, I successfully added macOS support, allowing us to reuse all packages we've developed over the past years.

Packages for networking, authentication, tracking purposes, and UI are all transitioned and ready to be reused. Best of all: they're heavily tested, allowing us to validate functionality while running tests for macOS.

In the past, I've had projects in which we decided not yet to build packages since it wasn't needed then. We didn't prepare for the unexpected, which I'm glad we did now at WeTransfer.

Enjoy this week's SwiftLee Weekly!

THIS WEEK'S BLOG POST

Those that worked with Objective-C probably remember the NS_OPTIONS type. I remember using it often back in the day, but I realized I only sometimes use the Swift equivalent. Therefore, I decided to dive deep into Swift's OptionSet and am convinced to use it more in my code.

This is my go-to operator when I try to find an even or odd number. Sarun W. explains how the operator works and how you can use it.

This is a good reminder by Marco Eidinger ‍ that we can use labeled associated values. If you ask me, this should be the default to improve readability. However, I wouldn’t be surprised if many of you are unaware of this possibility.

Every time I see stride in Swift, I wonder why I don’t use it more often. It’s a matter of keeping it on top of mind since it can be helpful in many cases. Keith Harrison explains how it works.

I love that Josh “ Conf” Holtz published a post on the blog of an employer that makes it easy not to use StoreKit 2 directly! Nevertheless, I know some of you implement purchases without 3rd party frameworks, for which this is an excellent article.

Those that know me also know I’m tall! I can’t wait to try this measurement feature explained by Leonardo Pugliese at the next iOS conference.

Have you ever seen the CarPlay Simulator? I’ve been using it a long time ago but didn’t see a recent version until this article written by Moritz Philip Recke.
