With AI agents these days all the fluff in the software can be replaced by doing the right thing as the time taken now to do the right thing is drastically reduced thanks to AI agents
We didn't forget about mobile, especially Android. Inspired by React Native, it drives the OS-native view layer through the same Rust codebase as the new desktop app. I think it might be the most responsive app on my phone now?

Today if someone tries to make money by building an idea others will take max 9-30 minutes to open source it. Just wild how things are these days

Apple is really out here releasing projects Steve Jobs shelved. The crazy part? People will still buy a broken product just because of the logo Really miss Steve’s vision. M-series is the only real highlight of post jobs era

Leet code is dead 💀 Software engineering is dead 💀 Writing code is dead 💀 Writing tests is dead 💀 Reviewing code is dead 💀 Reading tech books is dead 💀 LLD is dead 💀 Tech X is just a funeral home with Wi-Fi at this point.

Someone has a good sense of humor at @expo 😂😂

Give it time, developers will extend their app support to Duo and we can all calm down, can’t say the same for the hardware issues am seeing for a $2,000 phone😖

Medical reports lost in your camera roll or paper bundle stacks? I built EkAyu with my friend @NirajTiwari_ to keep your family’s health records organised, private and easy to find. Free on iPhone & iPad. Download 👇 apps.apple.com/us/app/ekayu-…

My buddy was irritated with one issue that he was having, and he and I had been working for a month to build something. It was fun, it was learning, and it was having a good sense of accomplishment in solving a real problem in daily life. More to come

You are a good developer till the time these agents don’t start hallucinating in a codebase you have either vibe-coded or have no clue what the AI coded till now. Good day 🌻

What skills are you using for SwiftUI project? Is there any repo you can point at or any of your personal recommendations?

As AI usage increases in the IT sector, junior devs who once took 6–7 years to become senior developers will now skip mid-level, senior, and tech lead becoming solution architects in 2 years and CTOs in 3

Temporary hacks quietly become permanent technical debt. Even when a language or framework adds native support for a feature, codebases almost always keep the old workarounds anyway. The feature ships, but the cleanup never happens.

AI can accelerate implementation. It cannot replace engineering judgment. And no, a lengthy skill or spec file doesn’t solve that problem. Lessons I’ve learned building software with AI codecat15.medium.com/lessons…

WWDC26 brought some serious SwiftUI upgrades 👀 I broke down 5 changes iOS devs should know: • Toolbar APIs • Document API • Reordering • Swipe Actions • Performance + Data Flow Bookmark this if you build with SwiftUI. 🧵👇

The Performance & Data Flow updates are worth paying attention to. AsyncImage caching, lazy @-State initialization, ContentBuilder, and Xcode 27 build-time improvements can impact real production apps.

That’s the full breakdown. Follow @codecat15 for more SwiftUI, iOS, and Apple developer content. Repost this for another iOS dev catching up on WWDC26 🚀 #SwiftUI #iOSDev #WWDC26

The way some accounts post these days is truly exhausting & immature. - AI will make your job obsolete - Did you know what just happened? - Someone just crashed the real estate industry Appreciate progress without turning every update into fear-mongering for engagement & like.
