iOS 27 Is Here. What Can Developers Build Now?

Tech Tuesday 💻

iOS 27 is finally here.

Of course, there are plenty of articles explaining the new features.

But as a software engineer, I'm more interested in a different question:

What can we build now that was harder — or impossible — before?

One of the biggest changes is the way AI, the operating system, and apps are becoming more connected.

Siri is becoming more capable of understanding context and interacting with app actions. Apple is also expanding App Intents, giving developers more ways to expose what their apps can actually do to system-level experiences.

That means the interaction doesn't always have to be:

Open app → Find feature → Tap button → Get result

It could become:

User expresses intent → AI understands → App performs an action

That's a pretty big change in how we think about app development.

AI isn't only inside the app

There's another part of Apple's update that caught my attention.

Xcode 27 is also moving further into agentic coding.

So we're seeing AI in two places:

AI helps users use software.

And:

AI helps developers build software.

This is something I've been thinking about recently with AI agents like Grok Bot too.

The interesting shift isn't simply that AI models are getting smarter.

It's that we're giving them more:

• tools
• context
• memory
• access to applications
• ability to take actions

The model provides the intelligence.

The surrounding system gives that intelligence a way to act.

So what should developers think about?

I don't think the first question should be:

“How do I add AI to my app?”

Maybe the better question is:

“What should my app be able to do when the operating system understands what the user wants?”

That's where I think iOS 27 gets interesting.

Every major platform update gives developers new APIs.

But the most exciting updates aren't always the ones that give us another API.

They're the ones that change what we think is possible to build.

What will you build with iOS 27?

Happy coding, happy Tech Tuesday. ☕️
