As a trunk-based development fan, feature flags are vital for me. Every recent feature I work on has a feature flag for debug and TestFlight builds. Since I merge branches even when features aren’t fully implemented, I use feature flags to disable them.

Another task view modifier allows observing equitable data and running the async task whenever it changes. The task lifecycle is still tied to the view lifecycle, but SwiftUI cancels the ongoing job and creates a new one when id changes.

Functional core Imperative shell in Swift. Unidirectional Flow. A few weeks ago, we talked about the idea of Functional core and Imperative shell in Swift. The goal is to extract the pure logic using value types and keep side effects in the thin object layer.…

Using coding agents doesn’t mean you should solely rely on their code. Define your boundaries to achieve better results. The Functional Core - Imperative Shell approach allows me to get nice code from agents.

SwiftUI introduced a view modifier called visualEffect. This modifier allows us to attach a set of animatable visual effects by accessing layout information of the particular view. Here is the example of sticky header view that can be placed in a scroll view.

SwiftUI allows us to maintain the structural identity of our view while changing the layout container using the new AnyLayout type. This type erases the layout type that depends on the current dynamic type size, preserving the structural identity of our view.

I’ve noticed that the infinite thinking issue occurs occasionally when using Codex-5.3 in Xcode. Do you experience the same problem?

Whenever you have installed the latest Codex on your Mac. You can make it available for Xcode.

ln -sf $(which codex) ~/Library/Developer/Xcode/CodingAssistant/Agents/Versions/26.3/codex

I’m not a fan of vibecoding, but since I’m a big fan of pair programming, I work in pairs with Codex.

I’ve been using Codex from the very beginning, exclusively from the terminal. However, I’ve come to genuinely enjoy having it integrated into Xcode. It feels more intuitive to review the code it generates. It’s akin to pair programming, which I thoroughly enjoyed.

There are three tag types: initial install, prefetched, and download-only. Prefetched and initial install tags are downloaded from the App Store with the app binary. Download-only tags are downloaded only via an API, but their usage is the same.

I made this onboarding before Claude Code or Codex existed. I made it open source on GitHub, so take it if you want.

Happy  26.3 Release Candidate day, everyone!

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,

SwiftUI provides us the fileImporter view modifier allowing us to enable file-picking user experience easily. It completely handles the dialog and navigation between folders.

What’s the easiest way to make a view fit its parent? The new containerRelativeFrame view modifier lets us set the view’s frame relative to its parent. It offers many customization options, but here’s the simplest one.

MetricKit helped me understand my app’s background memory usage and identify reasons for system pressure terminations. I then made changes to reduce background memory usage, keeping my app active without system termination.

You can effortlessly create a reusable parallax header in SwiftUI using the onGeometryChange view modifier. All you need to do is track its offset and gradually slow it down as you scroll.

SwiftUI framework introduces a trigger value pattern across its APIs. Trigger value allows us to attach a view modifier that runs its action whenever the trigger value changes.
