❓Why does my model return different data than my tool?
💡The model processes tool output and forms its own response with that data. The model's output is a String, not the raw tool data structure.

❓How can I tell AI Transcript Entry objects apart?
💡The LanguageModelSession (AI model) keeps a transcript of prompts and responses. You can loop though it and do a switch on the entry type.

❓Can I use Limited Availability Checks in the Instructions?
💡Yes! You can use limited availability checks right in your Instructions builder. The Prompt builder has a special buildLimitedAvailability function that knows how to handle availability checks.

❓How do I show when a session is processing in SwiftUI?

⭐️My favorite perk is the community. ☺️
Super nice people, all going through the same journey as you.

@seanallen_dev This is great info to share with your audience, because this is the kind of knowledge that I think a lot of developers (or entrepreneurs in general) struggle with.

❓When should you prewarm the prompt prefix in SwiftUI?
💡Prewarm it right when the view appears using .onAppear, or when picker values change since they're used in the prompt prefix. This prepares your AI prompt ahead of time.

⭐️I like how Apple is giving us SwiftUI skills that we can export from Xcode 27 to use in our own IDEs. 👍

I’ve definitely been thinking a lot about making content on my learnings and experiences.

I’ve had the fortunate opportunity at work to learn a variety of tools and methods and automations. Our company has embraced AI and gave us quite the budget to experiment with a lot of the tools out there.

At work, I’ve given many presentations but I’ve never shared anything publicly because I’m thinking it’s always changing.

But I don’t know, maybe I should reconsider.

🏳️Time to face obvious facts. iOS Dev courses are no longer viable income for me. I've been disrupted.

I'm looking to join a team working on a cool iOS project (full-time or part-time contract). Remote.

RT's are appreciated! DMs open.

[Mark Moeykens @BigMtnStudio]

That’s exactly what I think too.

I’m in many groups and the favored AI tools and tech changes almost weekly.

“This is the best. Now this. Now that is too slow. Now this one is too expensive. This one has this new feature. Now they all have that new feature.”

Around and around it goes.

❓What is one way to format currency values in SwiftUI?
💡Use Text with .currency format parameter and specify currency codes like "USD", "EUR", "GBP", or get the locale's current currency with locale.currency?.identifier.

❓How do I create links with different button styles in SwiftUI?
💡Use the Link component with buttonStyle modifiers like .bordered and .borderedProminent, plus shape modifiers like .capsule or .roundedRectangle for beautiful, tappable links.

❓What is a quick and easy way to create color gradients in SwiftUI?
💡Every color has a gradient property that transitions from a lighter version to itself. Simply use .fill(color.gradient) on shapes like RoundedRectangle to create gradients.
