I mostly write about Swift, Objective-C, iOS, open source, and other software development topics. Sometimes I write about the ethics of tech, labor, and politics. I also write satire pieces, personal essays, and notes on what I'm currently reading.
I recently setup fastlane for one of my indie apps, Taxatio, to automate uploading builds and metadata to the App Store — by far, one of the most tedious tasks of app development. While I had used fastlane extensively before when working on teams at companies, I had never actually set it up from scratch. In this post, I want to share how to do that, as well as a lightweight configuration that I think works well for solo indie developers — folks on a team of one!
My Mac menu bar apps, Red Eye and Lucifer, are now for sale on my new Gumroad store.
Perhaps “quirks” is not the correct description, but I recently encountered some unexpected behavior when modifying a protocol in Swift. While I was initially slightly confused, how Swift handles protocol requirements does make sense — conformances are more lenient than you might think!
Providing screenshots for the App Store has always been a tedious and time-consuming process. But as the number of differently-sized iOS devices has grown and changed over the years, it has become more difficult to manage. (This is why the developer community built tools like fastlane snapshot.) The screenshot requirements for the App Store have increasingly become a burden for developers, especially indies. With the Mac App Store, there are fewer hurdles and less strict requirements. However, if you are now targeting only the latest OS releases and latest hardware, the screenshot requirements for both App Stores are not only burdensome but they no longer makes any sense!
While working on updating iOS screenshots for the App Store recently, I discovered that simctl status_bar is still broken. And unfortunately, I do not expect it to be fixed any time soon.
I’m happy to share that I released an update to Taxatio today, but unfortunately it was not without a lot of friction and hassle with the App Store approval process.
Continuing another tradition, here are the books I read in 2023. Similar to my previous post highlighting my top posts of 2023, I also skipped publishing my reading list last year, for 2022. Again, I was simply too burnt out by the end of that year. I also did not read that much compared to previous years — thanks again to burnout. You can find previous years here under the #reading-list tag.
To continue my (almost) tradition of sharing my top posts, here are my most popular posts of 2023. You can find previous years here under the #top-posts tag. Last year, 2022, is notably absent from this series — I was too burnt out last year (for a number of reasons) to write one of these posts. So as a bonus, I’ll include my top posts of 2022 here as well! As usual, all of my analytics data is publicly available, made possible by the excellent GoatCounter Analytics, so you can view it too.
Last week I wrote about setting up a new MacBook Pro — my first Apple Silicon Mac, and thus my first MacBook with a notch. I lamented how poorly macOS interacts with the notch, specifically how menu bar apps and icons simply get hidden if you have too many to display. Lots of folks on Mastodon offered various solutions, and some readers emailed me with options as well. I figured it was worth making a separate post about this specific issue to list all of the workarounds and alternatives. It is clear that this is a widespread problem that users are having.
With the recent announcement that Threads.net is starting to integrate with ActivityPub, I figured it would be a good time to remind folks that you can follow me on Mastodon at @jsq@mastodon.social. Many of my connections have moved over from Twitter — but sadly, not all of them. Although, some have moved over to Threads. If you would like to join Mastodon.social, you can use my invite link.
Welcome to the fourth (and I think final!) part of my going indie series! Previously, I discussed the exciting topics of business structure, taxes, and retirement. Today, I’m going to discuss two final topics: bookkeeping and invoicing. The first is about how to correctly track your income and expenses, and the second is about making sure you get paid! Because this is capitalism, baby — we are not here for passion, we are here to pay those bills.
I recently discovered, while setting up my first Apple Silicon Mac, that Xcode does not have access to your shell environment. But there’s one caveat to that. (Thanks to Boris for confirming!) This post will hopefully be a reminder to my future self when I encounter this issue again.
After setting up my new M3 MacBook Pro, I decided to do some quick performance comparisons with my old Intel machine. Anecdotally, I would have told you that it is insanely faster but seeing the data made my jaw drop.
I typically try to keep devices for as long as I can — historically, that’s been around 5-6 years for laptops. During the Intel era of MacBooks, the year-over-year spec bumps were usually not impactful enough to justify more frequent upgrades. However, the transition to Apple Silicon has changed that. I recently upgraded to my first M-series MacBook Pro.
A few weeks ago my AirPods Pro 2 (with Lightning, not USB-C) suddenly started acting buggy and weird. The case no longer made the chime sound when plugging them in to charge. I stopped getting “Left Behind” notifications from the Find My app. After updating to iOS 17, I could not get them to install the latest firmware, which enables the new features for Adaptive Audio, Conversation Awareness, and Personalized Volume. I had been trying for weeks to follow the magic steps that will trigger a firmware update with no luck. Even worse, after a full charge of both the AirPods and the case, the batteries for all of them would drain to zero percent within 2-3 days.
When you work on a large team and are participating in many pull requests on GitHub, it can be difficult to keep track of everything you are working on. In addition to opening your own pull requests, you can be assigned to them, you can be requested as a reviewer, you can comment in discussion threads, and you can be mentioned by others. Each of these occurrences requires your attention — perhaps immediately, but always eventually.
Foundation’s URL (née NSURL) is a nearly ubiquitous API on Apple platforms. One of its shortcomings is that it is heavily overloaded – an instance of URL could represent a web URL or a file URL. While there are many similarities between accessing resources on a local disk or on a web server, I think there should be explicit types for each, say WebURL and FileURL.
Welcome to the third part of my going indie series! In the previous post, I discussed building a foundation, getting started, and finding clients. In this post, I am going to discuss many of the decidedly un-fun administrative aspects of being freelance and contracting like saving for retirement and — everyone’s favorite — taxes. Most folks consider these topics to be boring and tedious, but understanding them is critical to your success. The best approach is one of curiosity. As a software developer, you might find the task of optimizing (and minimizing!) your tax burden to be an interesting problem to solve — I definitely do!
In UIKit, UITableViewCell has a customizable accessory view. You can use one of the few accessory options that is provided by iOS by setting the accessoryType property, or you can provide a custom view using accessoryView, which can be any UIView. The equivalent of constructing a UITableViewCell with a chevron accessory in SwiftUI is using a NavigationLink. Unfortunately, however, SwiftUI does not provide an API to customize the accessory view for a NavigationLink — you are stuck with the default chevron.
UserDefaults is probably one of the most popular APIs on Apple Platforms. It is a highly-optimized key-value persisted store that is backed by a property list, and it is most commonly used for saving small pieces of data like user preferences. Despite its ease-of-use, there is one common anti-pattern I see developers use often.
Xcode 15 introduces a new “bookmarks” feature, which lets you bookmark lines or entire files. It is a welcome change that has sherlocked my hack for using breakpoints as bookmarks.
Beginning with the introduction of dark mode in iOS 13, colors in iOS are now (optionally) dynamic. You can provide light and dark variants for all colors in your app. However, I was surprised to find that SwiftUI — which also made its first appearance on the platform in iOS 13 — still does not provide any API for creating dynamic colors.
Welcome to my next post on going indie! In the previous one, I provided a high-level overview and introduction, and answered some of the most common questions I get from folks. In this post I’m going to dive deeper into how you can prepare to go independent, how to find clients, and other tips.
I recently asked on Mastodon for tips on estimating your total number of RSS subscribers. It turns out it is rather easy to do. While I do have (privacy-aware) analytics for my site, this only tracks page views.
When you display text in your app, you might come across situations where the text layout produces undesirable results under certain layout constraints. The text could wrap on smaller devices or be truncated in certain localizations. At this point, we are well-equipped with adaptive APIs to make our layouts work on all screen sizes — for example, we have Dynamic Type, Auto Layout, and UITraitCollection.
I’m excited to share that I recently released a new app, a tax calculator for freelancers called Taxatio. It is specifically for self-employed sole proprietors based in the United States — freelancers, consultants, independent contractors, and indie developers (like me!). One of the more confusing and difficult aspects of going independent is taxes. And that’s why I made this. It is a multiplatform SwiftUI app for iOS and macOS available as a universal purchase on the App Store.
A number of folks have reached out to me recently (and over the years) asking me about my experience going indie. I originally wanted to write this reflection after my first year, but I could not find the time nor motivation. The early days of the pandemic really drained me. However, I hope these past three years of experience will only make this post more valuable to those seeking to do the same thing I did. I am writing this for anyone who is interested in trying to go independent — either with your own app development business, solo contracting and freelancing, or both.
Whether you are starting a new job or joining a new project, getting oriented in a new iOS codebase can be difficult and overwhelming. It is particularly hard if the codebase is very large, and especially challenging if you are early in your career and do not yet have much experience to draw from.
I grew up in the 90s and early 2000s. I was a skater kid and when I wasn’t skateboarding I was playing Tony Hawk’s Pro Skater on my Playstation. That scene introduced me to punk music, which eventually led me to hardcore music. By my early teens I was going to shows nearly every week with my friends.
