I have worked on apps for years and accessibility is one of those things I barely thought about in the beginning. You hear about it. You know it matters. But most teams are busy shipping features and fixing bugs, so it quietly gets pushed aside.
A lot of “good accessibility” is just thoughtful product design. One thing we started doing internally after that was testing features with: - larger text enabled - reduced motion enabled - VoiceOver turned on - darkMode enable etc.
"AI won’t replace software engineers.”
Meanwhile software engineers:
- using AI to write regex
- asking AI why the regex broke production
- asking AI to explain the regex AI wrote
- pretending they understood the explanation in standup
@twannl Congratulations 🎉. Well deserved.
Brandon and Stephen from @pointfreeco must be added to the list. And @azamsharp and @BigMtnStudio and there are others who has done so much for the iOS dev community as well.
Swift 6.3.2 is available! 🛠️ This maintenance release includes updates to Swift Package Manager and Swift Build, making it easier to load package resources on background threads. More here:

If you’ve dealt with painful mobile architecture decisions before, repost this for your team.
Also curious:
What’s the worst architecture anti-pattern you’ve had to clean up?
Good architecture isn’t about over-engineering.
It’s about protecting future development speed.
The best teams don’t just optimize for shipping fast once.
They optimize for shipping fast repeatedly.
The interesting part is that none of these issues hurt immediately.
That’s why teams ignore them early on.
The app still ships.
Everything feels “fine.”
Until development velocity suddenly disappears.
What works better:
API models become domain models, and domain models power the UI.
That separation gives flexibility.
Backend changes become manageable.
New APIs become easier to integrate.
UI becomes more stable long term.
The third mistake is tight API coupling.
Backend changes one response field…
…and suddenly multiple mobile screens break.
Why?
Because raw API models are directly connected to the UI layer.
The second mistake is skipping offline handling completely.
A lot of apps still assume users always have stable internet.
Real users don’t.
That’s why so many apps feel unreliable in daily use.
One architecture shift changes everything:
Instead of:
API directly powering the UI
Use:
API feeds local database, and local database feeds the UI.
This makes apps:
feel faster
work better on weak networks
recover gracefully
reduce loading states
