Weekly Newsletter Issue 101

Weekly newsletter summing up our publications and showcasing app developers and their amazing creations.

Welcome to this week's edition of our newsletter.

We're back after celebrating our 100th edition, and what a week it's been. From the WWDC26 announcement to the Swift Student Challenge winners (congratulations to the winners and to everyone who took on the challenge), and yesterday the invites to join the event at Apple Park!

If you got chance to attend in person, it’s truly an incredible opportunity, not just to attend, but to connect with the community. There’s nothing quite like being surrounded by people who share the same passion for building on Apple platforms.

And if you didn’t get the chance this time, don’t worry. WWDC week is still filled with amazing community events, side gatherings, and opportunities to connect.

XCTest in iOS: interview essentials

Artem provides, in one of this interview-focused articles, an overview of XCTest fundamentals covering key concepts and their use in real iOS projects to help you prepare for interviews.

XCTest in iOS: interview essentials → Livsy Code
Greetings, traveler! Unit testing often comes up in iOS interviews, yet many developers have limited hands-on experience with it. Some teams barely use tests, some cover only a narrow slice of the codebase, and some rely on a few integration checks while calling them unit tests. Interviewers know that. They usually care less about whether

Indie App of the Week

Xarra

Xarra turns articles, documents, and other text into audio, while keeping them visible and synchronized on screen. With support for line and word highlighting, chapter navigation, automatic resume, and flexible import from URLs, pasted text, and documents to make longer reading more manageable.

The app developed by Daniel is well integrated into the system. The Share extension lets you send content from Safari, Notes, or any other app, iCloud sync keeps your progress across devices and platforms and it ties into system playback controls through Now Playing, the Lock Screen, and Control Center. Automatic chapter detection makes longer documents easy to navigate while content stays on device and works offline once imported. Accessibility runs through the whole experience rather than sitting on top of it and it's well integrated into the features, with support for assistive technologies and user preferences.

Apple updated the documentation for the coding intelligence features in Xcode, a feature that has become increasingly central since Xcode gained support for agents.

Writing code with intelligence in Xcode | Apple Developer Documentation
Generate code, fix bugs fast, and learn as you go with intelligence built directly into Xcode.

This latest addition takes it a step further, allowing external agents to interact with Xcode and enabling a more integrated, automated development workflow.

Giving external agents access to Xcode | Apple Developer Documentation
Let agents access your project and Xcode capabilities using the Model Context Protocol.

We can’t wait to see what you will Create with Swift.

See you next week!
