Apple’s Xcode 26.3 Release Candidate Adds Agentic Coding Tools for Developers

The Release Candidate of Xcode 26.3 is rolling out as we publish this with brand new agentic coding capabilities. With the update, developers can connect to either OpenAI’s Codex or Anthropic’s Claude Agent to assist their development work.

The agent sits in Xcode’s sidebar where developers can use it to plan new features, implement them, and review the results. As developers work, the agent generates a transcript of its actions, which lets developers follow along and interact with it. For example, code snippets will appear in the sidebar that can be clicked to take developers directly to the spot in the file where the agent made a change. Code updates can also be simultaneously previewed. Plus, by building OpenAI and Anthropic’s agents into Xcode, the agents have the benefit of the latest Apple APIs and documentation, which should result in better, more modern code.

Xcode 26.3 also integrates with Model Context Protocol, the open standard used to connect coding agents to other tools. That will allow any MCP-compatible agents to work with Xcode, running inside or outside Xcode, which broadens the possibilities for developers even further. Having watched a short demo of Codex assisting in the development of features in Xcode, version 26.3 looks as though it has a lot of potential to make experimentation easier and to iterate more quickly on ideas.

I’ve been building a couple of different apps recently, mostly from Terminal, which works but isn’t ideal. There are lots of apps out there that try to solve the agentic coding problem, including Visual Studio Code and Codex, which I covered yesterday. However, having seen a demo of Xcode in action, it’s jumped to the top of my list to try. After all, it’s an app with which I’m already familiar, and with Apple’s documentation and API knowledge baked in, my hope is that it speeds up my workflow even further.

For developers who want to learn more, Apple is holding a code along session Thursday covering the update.


OpenAI Launches Codex, a Mac App for Agentic Coding

Today, OpenAI released Codex, a Mac app for building software. Here’s how OpenAI describes the app in its announcement:

The Codex app changes how software gets built and who can build it—from pairing with a single coding agent on targeted edits to supervising coordinated teams of agents across the full lifecycle of designing, building, shipping, and maintaining software.

On first launch, Codex requests permission to access the file system. I granted it access to a subfolder where I stored all my projects, along with the folder that houses an app I’ve been building in my spare time. Those folders and projects live in the left sidebar, where each can be expanded to reveal chat sessions for that project.

Access to your other development tools.

Access to your other development tools.

In the toolbar is an Open button for accessing other development tools installed on your Mac, a Commit button for managing version control, a button that reveals a terminal view that expands up from the bottom of the window, and a diff panel for reviewing code changes. In settings, you’ll find additional customization options, along with tools to hook up MCP servers and integrate skills.

Codex is not your traditional IDE. Agents are front and center, which in an app that is far more natural to use if you’re new to agentic coding, but the model is similar. While I write this article, Codex has been grinding away in the background performing a code review of my app. After spending time reviewing all the files, Codex asked permission to run commands to do things that it can’t accomplish inside its sandboxed environment.

Automations.

Automations.

The capabilities of Codex are enhanced by skills. OpenAI is kicking off the launch of Codex with a bunch of skills that you can access via its open-source GitHub repo. The app includes a selection of pre-built Automations for repetitive tasks, too.

All in all, Codex looks excellent, but it will take me some time to get a sense of its full capabilities. If you’re interested in trying Codex, you can download it from OpenAI here. For a limited time, the company is making the tool available to Free and Go subscribers, for whom rate limits have been temporarily doubled, as well as Plus, Pro, Business, Enterprise, and Edu users.

Immersive Dog Show Series ‘Top Dogs’ Premieres on Apple Vision Pro

Pet lovers, rejoice! After debuting immersive series and specials on subjects ranging from nature and travel to music and sports on the Vision Pro over the past couple of years, Apple is now inviting viewers into the world of competitive dog showing with Top Dogs. Available now, the two-part docuseries offers a one-of-a-kind perspective on Crufts, the world’s biggest dog show, following competitors and their owners as they give their all in hopes of winning the coveted Best in Show trophy.

Let me tell you: having had a chance to see the docuseries, these are some very good dogs. Throughout the roughly 30 minutes of video, I got the chance to see tons of adorable and prim canines, some from breeds I’d never heard of before. Crufts attracts nearly 20,000 competitors each year, so there were plenty of great dogs to meet. It’s worth watching the show just for the shots of the cute pups alone.

But Top Dogs is about more than just making new canine friends. The series offers a great overview of the dog show itself, including some behind-the-scenes footage of the lower-level competitions I wasn’t familiar with from my casual viewings of dog shows in the past. The series also employs the best use of graphics I’ve seen so far in Apple Immersive Video, explaining the dog show’s various rounds with expansive 3D charts. It includes an excellent opening title sequence, too, something I didn’t realize I was missing in these immersive series up until now.

Apple Reports Q1 2026 Revenue of $143.8 Billion

Today, Apple reported its 2026 Q1 earnings, posting quarterly revenue of $143.8 billion a 16% increase from a year ago.

Apple CEO Tim Cook had this to say of the results:

Today, Apple is proud to report a remarkable, record-breaking quarter, with revenue of $143.8 billion, up 16 percent from a year ago and well above our expectations. iPhone had its best-ever quarter driven by unprecedented demand, with all-time records across every geographic segment, and Services also achieved an all-time revenue record, up 14 percent from a year ago. We are also excited to announce that our installed base now has more than 2.5 billion active devices, which is a testament to incredible customer satisfaction for the very best products and services in the world.

As CFO Kevan Parekh noted in Apple’s press release, today’s results set an all-time earnings-per-share record, with an 19% increase and $54 billion of operating cash flow.

So yes, Apple continues to make a lot of money. Global trade politics, currency exchange rates, component prices like RAM, and other factors are all risks that could put a damper on the company’s earnings in the future, but so far, the company is doing fine.

Creator Studio Review: Redefining Pro for the Modern Era

Starting today, Apple is offering a subscription bundle of its creative apps called Creator Studio. Some of what’s included is exclusive to the subscription package, while other parts of it remain available à la carte. It’s a lot to absorb, and I’ll get to all the details in due course.

However, what’s most exciting to me is the fact that Apple is clearly repositioning these apps to appeal to a broader cross-section of creatives. Apps like Final Cut Pro and Logic Pro are no longer just for Hollywood and music studios. By filling out the iPad lineup and adding Pixelmator Pro along with enhanced versions of their productivity apps, Apple has taken the first steps toward realigning its apps with what it means to be a creative professional in 2026.

This transition isn’t the sort of thing that happens overnight, which is why it’s easy to spot the gaps in Creator Studio’s offerings. I ran into a couple of bugs along the way, too. However, by and large, I think the bundle of apps hits the right notes and is heading in the right direction. Let’s take a closer look.
