Localization troubles with Swift PM

Scott Berrevoets — Fri, 19 Sep 2025 00:00:00 -0700

A few weeks ago we got bit by a piece of Apple magic in its localization workflow when combined with Swift PM. The problem we ran into was that as soon as we moved all our Localizable.strings files to an SPM package, none of the localizations would be picked …

Re-binding self: the debugger's break(ing) point

Scott Berrevoets — Wed, 08 Aug 2018 00:00:00 -0700

Update 07-29-2019: The bug described below is fixed in Xcode 11 so this blog post has become irrelevant. I'm leaving it up for historical purposes.

For the Objective-C veterans in the audience, the strong-self-weak-self dance is a practice mastered early on and one that is used very frequently. There are …

Using Interface Builder at Lyft

Scott Berrevoets — Mon, 06 Mar 2017 00:00:00 -0800

Last week people realized that Xcode 8.3 by default uses storyboards in new projects without a checkbox to turn this off. This of course sparked the Interface Builder vs. programmatic UI discussion again, so I wanted to give some insight in our experience using Interface Builder in building the …

Keeping the Lyft iOS App Accessible

Scott Berrevoets — Wed, 18 Jan 2017 00:00:00 -0800

Note

This article was written by me but originally published on the Lyft Engineering Blog.

At Lyft we’re in a unique position: every day we work on an app that affects people in the real, physical world — not just the digital one. This has an especially large impact on …

Silencing NSLog

Scott Berrevoets — Mon, 01 Aug 2016 00:00:00 -0700

When your app has a lot of third-party dependencies, what often happens is that those libraries log a bunch of things to the Xcode console to help their own debugging. Unfortunately, a lot of these logs are useful only to the developers of the library, but not the developers of …

Outlets: strong! or weak?

Scott Berrevoets — Mon, 21 Mar 2016 00:00:00 -0700

There are a lot of styles out there when it comes to using Interface Builder outlets in Swift. Even Apple's documentation and sample code isn't always consistent. The most common one, the one Apple uses in its sample code, follows this pattern:

@IBOutlet private weak var someLabel: UILabel!

Let's break …

@objc class prefixes fixed in Xcode 7 beta 4

Scott Berrevoets — Thu, 23 Jul 2015 00:00:00 -0700

Back in December I wrote about what I thought was a bug in the Swift compiler that would expose the wrong class name for a Swift class in Objective-C. I then later found out everything worked as intended and I had just misunderstood what @objc() exactly did. Apparently it was …

The power of UIStackView

Scott Berrevoets — Sat, 13 Jun 2015 00:00:00 -0700

I was in the audience for "Implementing UI Designs in Interface Builder" at WWDC, where Apple touted UIStackView as a new, better way to lay out your views that in a lot of cases didn't require Auto Layout.

While the presentation looked good, I wasn't quite sure this solved a …

@objc creates a wrong class name in Objective-C

Scott Berrevoets — Mon, 15 Dec 2014 00:00:00 -0800

A few months ago, I decided I'd get started porting SDCAlertView to Swift, but I was only a few minutes in until I ran into a problem I had no idea how to solve: I couldn't get my class names right in both Swift and Objective-C. Even though there are …

Dev-only iPhones

Scott Berrevoets — Mon, 20 Oct 2014 00:00:00 -0700

With today's release of iOS 8.1, most app developers are looking at 4 significantly different iOS versions they will be supporting: iOS 7.0, iOS 7.1, iOS 8.0, and iOS 8.1. Factoring in the number of devices (iPhone 4S, iPhone 5, iPhone 5s, iPhone 6, and …

UIMenuController and the responder chain

Scott Berrevoets — Mon, 15 Sep 2014 00:00:00 -0700

The responder chain is a very important paradigm in the world of iOS development, and not terribly hard to understand. Dozens of articles have been written about it, and with some examples, the concept of finding a responder to a certain event by traversing a chain of potential responders is …

Xcode & Objective-C Oddities

Scott Berrevoets — Sun, 10 Aug 2014 00:00:00 -0700

Any developer that has worked with Xcode to write a little more than just "Hello, World" knows that Xcode and Objective-C have their quirks. Chances are you have heard of @TextFromXcode, the Twitter handle that portrays Xcode as a high school bully in fake text conversations like this:

But it's …

Objective-C prefixes: a thing of the past?

Scott Berrevoets — Fri, 25 Jul 2014 00:00:00 -0700

This past week, there was, again, a lot to do about Objective-C and prefixing. To most iOS developers, the story sounds familiar: one camp is strongly in favor, another camps is strongly against, and a third camp couldn't really care less.

Unless I'm unaware of any other platforms where the …
