Hello iOS devs, here are few commonly asked mobile system design interview questions

[Ravi @codecat15]

@MKBHD Myself and @NirajTiwari_ worked on getting our app EkAyu optimized for iPhone Duo with the Xcode beta version coz we wanted to be ready for this device.

[Ravi @codecat15]

Added Duo support to EkAyu app, please do check the app out.

@sarunw EkAyu: Family Health record

[Ravi @codecat15]

@dezinezync Awesome let me try that hope that works 🤞

[Ravi @codecat15]

I tried taking screenshots of pic from the XCode 27.1 RC of iPhone duo and all i get is a dark screen is that a bug???

[Ravi @codecat15]

@SwiftDev_UI I tried that and sadly it does not, the only time when it works is when the duo is in its folded state that’s when I can take the screenshots

[Ravi @codecat15]

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.

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

[Ravi @codecat15]

@viditb Excellent work

[Ravi @codecat15]

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 🌻

[Ravi @codecat15]

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

[Ravi @codecat15]

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

[Ravi @codecat15]

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.

[Ravi @codecat15]

@madskristensen Could the Exception Helper be resizable or respect the IDE font-size setting or have a setting of its own?

Its text is very difficult to read, have to increase the font size of the editor to get a decent read or copy paste the message in notepad to review the exception message.

[Ravi @codecat15]

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

@simplydt Fair question. I haven’t measured a production delta yet, so I’d avoid giving a % number.

The reason I called it out: Apple says AsyncImage now supports standard HTTP caching by default and respects server cache headers. That should reduce repeated image fetches when cacheable

[Ravi @codecat15]

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.

🧵👇

[Ravi @codecat15]

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

[Ravi @codecat15]

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.

[Ravi @codecat15]

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.
