A Behind-the-Scenes Look at How We Release the Spotify App (Part 1)
Releasing an application to the App Store is one of the most important parts of the development process - this is when users get access to new features.

Unfold's Modern Mobile Release Process and the Subtle Art of Making Them Boring
This is the second article I’m sharing about releases in this newsletter issue. But this time, the authors from Squarespace describe their release process as boring - because they don’t think much about it anymore.

It wasn’t always like this. In the past, the process often slowed mobile teams down. Here is how Squarespace moved from an eventful release process to a boring.

June is traditionally WWDC month - the time we get a glimpse of what’s coming in Apple’s operating systems.

This year, we saw the introduction of the new design language: Liquid Glass, and a shift to OS naming based on the year: iOS 26, tvOS 26, etc.

Of course, developers also get an updated Xcode 26, and naturally, there are some interesting new features coming to our beloved (or maybe not-so-beloved) IDE.

This issue of Curated iOS is about Xcode 26.

I’m excited to share the first guest post in Curated iOS by Robin Kanatzar!

Robin is an experienced iOS and Android engineer, as well as an accessibility expert. She has participated in numerous conferences as a speaker and recently authored a book on how to get started with conference speaking.

In today’s Curated iOS Quick Read issue, Robin shares why developers should speak at conferences.

Speaking at conferences sounds scary, especially if public speaking isn’t your thing, but the personal and professional benefits are 100% worth it. 

Sharing your passion and knowledge with your peers is a great way to give back to the tech community. Think about how much you’ve learned from others through blog posts, StackOverflow answers, or YouTube videos! Speaking at conferences is your chance to say “thank you” and pay it forward. 

If you’re from an underrepresented group in tech, you might just inspire someone else like you to take the stage, creating a ripple effect that makes the community stronger and more diverse.

Speaking gives you a professional boost as well. When you prepare a talk, you really dive into a topic and force yourself to understand it backwards and forwards so you can explain it to others. Your reputation as an expert in your field grows, you can meet potential new clients, and can even land your next job.

On a more personal note, you can make new friends who share your interests. Conferences are full of people like you who share your love of technology, and as a speaker you’re in a great position to attract friends who are passionate about your presentation topic.

Finally, don’t forget about the bonus perks: travel! Conferences happen all over the world, from Tokyo to Buenos Aires, and many will cover your travel and hotel if you’re a speaker. That means you can explore new places without breaking the bank. 

So, if you’ve ever thought about speaking at a conference, go for it! You’ll give back to the tech community, grow as a developer, and maybe even check off a bucket-list destination along the way.

For more tips and advice about getting on stage for the first time, check out Robin’s book Tech Talks: How to get started speaking at technical conferences

Happy Monday!

Monday Quick Read is a series of short articles, where I share my personal experiences and thoughts on software development, particularly iOS.

In a previous article, I talked about Feeling Overwhelmed with New iOS Releases?

Last week, my Curated iOS newsletter reached 1,000 subscribers — a milestone I couldn’t have achieved without your support.

Reflecting on this milestone, I began thinking about the value of creating and sharing content as a developer. What motivates someone to start a blog or newsletter? Here are a few of my reasons:

1. Gain new knowledge

   As software developers, we should always be learning. However, when working on the same app or stack for an extended period, we might lose the drive to explore new frameworks or APIs provided by the system. Sometimes, we aren’t aware that certain tools or features exist, let alone know where to find them.. Writing a blog or newsletter forces us to stay curious and keep an eye out for new information.

2. Support the developer community

   By writing or curating content, we can help other developers find useful information. We might even help people save some money through Subscriber Benefits :)

3. Expand networking possibilities

   Most developers are incredibly interesting people. Building new connections opens doors to new knowledge, fresh perspectives, and exciting possibilities.

4. Personal brand

   This one might be debatable, but I believe that the image a person builds around their expertise can potentially help find new opportunities.

So in today's issue, let’s have a look into iOS Communication patterns: Delegate, Target-Action, Notification-Center, Key-Value Observer (KVO).

Swift Delegate Protocol Pattern Tutorial
To get started with the Delegate Protocol pattern in Swift, I recommend Sean Allen’s video tutorial. His clear explanations and examples make it easy to understand how this pattern enables objects to communicate and delegate tasks effectively.

Delegate vs Closure in iOS Development
While closures aren't typically considered a communication pattern, Naresh Kukkala's article is an excellent resource for understanding two different ways to pass data between objects. The Delegate pattern allows one object to act on behalf of another by defining protocols that outline specific responsibilities, which are then delegated to other classes. In contrast, closures are self-contained blocks of code that can be passed around to execute specific tasks.

Newsletter recommendations

The iOS community is full of talented developers, and many of them run insightful newsletters and blogs. In this section, I’m excited to share recommendations for some of these great resources.

This week, I'd like to highlight the fantastic Coding with Vera newsletter by Vera Dias, where she shares insights and practical advice for iOS developers, covering everything from design patterns to productivity tips.

Target-Action Explained in Swift
The Target-Action pattern offers a straightforward way to manage user interactions in iOS. Primarily used in UIKit with controls like buttons, sliders, and views, it allows an object to respond to specific events, like a tap or a swipe. While I don’t have a specific article from the iOS community to share this time, I recommend checking out the Apple Developer documentation for an in-depth look at implementing Target-Action.

Bad practice: not using UIAction
Using the traditional Target-Action approach requires action implementations to be Objective-C compatible. Vincent Pradeilles demonstrates how to improve this by leveraging the addAction method, introduced in iOS 14. Unlike Target-Action, UIAction uses closures, offering a more modern, Swift-friendly way to handle actions without the Objective-C constraints.

In addition to the traditional Wednesday issues, I’m also sending out Monday emails featuring a series of personal articles called Monday Quick Read.

Even though there’s no new article this week, feel free to browse the archive of previous articles.

Notification Center in Swift
The Notification Center is a tool that allows objects to broadcast and receive messages without needing a direct reference to each other. It’s commonly used to respond to specific events, like data updates or settings changes. For a deep dive into this pattern, check out Begüm Ünal’s article where she explores Notification Center in detail.

Key Value Observer
KVO is a mechanism that allows objects to observe changes to specific properties in other objects. It’s commonly used when one part of an app needs to respond to state changes in other parts. To learn more about this pattern, check out August Lin’s article, which explores KVO in depth.
