For senior iOS devs: Does this match what you see with mid-level developers? What would you add to Level 1? I'm running a 6-week cohort on exactly this - if you're stuck in the "it works but it's messy" phase https://t.co/LPg9J6wZ2y

When I see iOS architecture courses jumping straight to Clean Architecture and modularization, I think they're skipping the part where most apps actually fail. Here's how I think about the three levels of architecture problems - and why Level 1 is where 90% of the work happens.

To understand the data flow and updating triggers in SwiftUI, its very helpful to draw the view tree diagram. Updates are passed down the view tree.

3 Ways to Debug SwiftUI View Updates in Xcode 26 - Find Performance Issues Fast In my new Yotube tutorial, I'll show you: -> Flash Update Regions - Xcode 26's new visual debugging feature (updated views flash yellow) -> _printChanges() - Track exactly what's causing view updates

Watch https://t.co/y72T1aP2ou to see how I build a SwiftUI app with Observation feature and Swift Concurrency. You can have a look at the Github repository here:

New Youtube video: Building an iOS Ghibli App with SwiftUI, MVVM, and Swift Concurrency In this SwiftUI tutorial, we dive into modern iOS development by building a Ghibli app using SwiftUI and MVVM architecture. We explore various aspects such as state management, async/await

The code behind this is a mess right now 😂 Using SwiftSyntax to parse, but tracking @State through view hierarchies gets complex fast. Still useful for understanding your own architecture patterns though.

Made a tool to actually see SwiftUI data flow 👀 Click on any @State, @Observable, or method and instantly see where it flows through your view hierarchy. Built it to teach architecture on my channel, but now I use it every day to navigate my own projects.

Biggest jump I have done so far. iPadOS 18 to 26

Is it just me or did SpotLight become more like Raycast

If you could work anywhere, where would that be?

swift concurrency feels like https://t.co/hr9IifRjmU

The demo project is a small children game app. It is quite fun with lots of drawing like Meshgrids and animations like the confetti. I will try to publish it this Thursday. Let me know if you are interested in SwiftUI animations.

It is working if I run the same code for macOS where I dont have this ugly box with the shadow arround the drag view:

Sometimes SwiftUI is just confusing. I am working on a tutorial project for drag and drop. But I am not able to change the drag preview. I am pretty sure this used to work. Was it always like this? Did something change? When did it change? Maybe its me?

i published a my first macOS app. It can help you with Xcode junk. You can get it for free here: https://t.co/u6wbMzpBCy

I only recently learned that simulator runtimes on my Mac take up SO much space! Check out how you cn clean up unused iOS versions (including betas) and free up tons of GB with a simple terminal command. You new Youtube tutorial 👇
