Developer tools and frameworks at Apple. I aspire to build delightful products, and to make others smile.

@__apf__ Lovely! Well worth the bike ride by the sounds of it! Congrats to you both.

SwiftUI packs so much power into just a few lines!

SwiftUI Tip 💡

Use projectionEffect() to create a skew effect on a view.

@wsdot_traffic Thank you for being such a reliable, well-updated source of information. You made our journey faster today!

Did Apple just kill every iOS vibe coding app?

Apple just dropped Xcode 26.3 with agentic coding.

Claude Code + Codex are now built into Xcode.

And with MCP support.

[Tim Sneath @timsneath]

@christoph_roh @gregjoz Yes, that's part of the feature. Agents can search documentation, explore file structures, update project settings, and verify their work visually by capturing Xcode Previews and iterating through builds and fixes.

[Greg Joswiak @gregjoz]

Xcode 26.3 with Claude Agent & Codex hits the Mac App Store today! With advanced reasoning capabilities in Xcode, you can streamline workflows and build faster. And MCP support lets you easily connect other compatible agents.

[Tim Sneath @timsneath]

@krzyzanowskim We think this is fixed in Xcode 26.4 beta 2, available from https://t.co/CTwbgV52qV. Let us know if you're still experiencing issues after installing this build!

[Tim Sneath @timsneath]

@krzyzanowskim Taking a look at this right now. Thanks for the report.

Thoughts on Xcode's 26.3's agentic coding:

- How to get skills working
- Use Xcode's MCP with other tools
- Impressions

using the new Xcode 26.3's agentic coding to build some interesting things 👀 Finally, we have agents living in Xcode that can ACTUALLY perform meaningful tasks, utilize MCPs, iteratively build, take screenshots, test and code - hype.

I showed my 12-year-old daughter how to chat to Claude using Xcode's Coding Assistant tab, and she spent the next two weeks building a game. It's out now on the App Store, and she's feeling very proud of herself ✨ https://t.co/za46grMDGt

@DmytroBavykin Release candidates aren’t uploaded to the App Store. The final release (soon) will be there.

[Tim Sneath @timsneath]

Major update for Xcode 26, with agentic coding support using MCP. You can download the release candidate of Xcode 26.3 now! https://t.co/sGWkXL3IPA

[Max Weinbach @mweinbach]

One of the coolest parts has gotta be connecting external coding agents to Xcode via MCP so you can use any agent for Xcode

[Tim Sneath @timsneath]

@Dimillian A small clarification: the agent can generate and view previews, and use those screenshots to iterate autonomously on the design. The blog from Anthropic describes this under "Visual verification with Previews": https://t.co/TgoXH8pSaR

Honestly so cool (and necessary!) to see Xcode break from only releasing large updates once a year to just releasing great stuff throughout the year!

Perhaps you've thought "I should learn SwiftUI", but have never known where to start? If so, then block out February 10th in your calendar. In one day, we'll teach you how to build great apps with SwiftUI: https://t.co/A8pMECEnXr

Gratitude to the Swift community -- it's been a big year on all fronts! https://t.co/4QfioxST4C @SwiftLang
