iOS Architect • 10y code • 7+ yrs shipping apps Architecture • Performance • Production war stories Building apps that don't crash at 3 AM #iOSDev #SwiftDev

After 7 years of iOS dev:
• 50+ apps shipped
• 10+ full rewrites
• Too many 3 AM prod fires 🔥
• Very strong opinions on architecture now

Time to share what actually works in production.

@jfaisal26 Impressions 3× with engagement dropping = algo loves something you're doing consistently now.
Mind if I DM? Building something similar rn and curious about your angle.

Most IT/product companies in India are now forcing full office return — even for top performers with consistent high ratings.
No WFH option at all.
Why are they so rigid about this in 2026?
Control? Culture? Real estate? Or just “because we can”?

@indiesoftwaredv That upload tho 🔥 time to deploy like a rocket

@DonnyWals Xcode 26.3 is carrying macOS Tahoe on its back for most iOS devs rn 😂

@roeymiterany 105 is insane — let's keep the streak going! 🤝

[Mani @maniappledev]

@waghnakh_21 Exactly.
Good prompting isn’t an AI skill — it’s a thinking skill with better output.
The clearer your head, the less garbage the model has to guess through.

@DanGW_92 2019 gang ✊
Xcode compiles → money saved → therapy funded.
Priorities 😭

[Mani @maniappledev]

@jfaisal26 Google: 28, survived antitrust, built AI moat, Cloud exploding 48% YoY, $400B+ revenue, 750M Gemini users
Apple: quietly prints $143B in one quarter on iPhone go brrr + 2.5B devices
Meanwhile I'm refreshing Xcode& praying the next macOS doesn't break 😂
Respect to both GOATs

@uzair_dev_ On it 🔥 Just smashed likes + RTs

@ios_dev_alb Haha yeah, the iOS 26 → iOS 19 swap is super common.

Did you try with skills/agents/rules?

@azamsharp “My Veggie Garden” looks super handy — grabbing it today.

What veggie are you most excited to grow this time? 👀
Happy planting! 🌱 #GardenLife

[Mani @maniappledev]

@rudrank Wow, that’s super smart timing — love how you jumped on the 2x limit right when it landed! 🙌

Thanks for sharing, really cool to see you stress-testing headless like this.

How’s Codex feeling so far compared to Claude?

Production lesson #1

Cold launch = first impression.
Apple: <400ms to first frame.
Most apps: 2–4s 😬

#1 culprit: SDK init blocking main thread in AppDelegate.

Not needed on first screen? Lazy load it.
Don’t let analytics kill your retention.

Unpopular opinion after 7 yrs iOS:

MVVM vs VIPER vs Clean vs TCA vs whatever….

Real questions:
→ New teammate gets it in 30 min?
→ Tests without mocking everything?
→ Survives 3 yrs of feature creep?

Pick one. Stay consistent. Ship.

Love @twannl 's lazy var guide!

Use lazy var only when:
• Data is immutable after init
• Computation is expensive
• You want caching behavior

Quick q: Why not a Swift Fundamentals Agent Skill repo? like your SwiftUI one

Open to contribute if you're game! 🙌
