Orchard: how Parsaa codes against today's Apple SDK, not last year's training data

Every large language model has the same blind spot: it only knows what it was trained on. For most code that is fine. For Swift, it is a real problem — because Apple ships a new SDK every single June, and a model trained last year simply cannot know it.

That gap shows up in two painful ways.

A raw LLM is always a year behind Apple

Stale training data. The model reaches for APIs Apple already retired — the kind Xcode flags the moment you build.

NavigationView { … } // deprecated

Hallucinated APIs. It invents method names and modifiers that look right, compile wrong, or do not exist at all.

.shadowStyle(.soft) // doesn't exist

You have felt both. You ask for a SwiftUI view, paste the answer, and Xcode lights up with deprecation warnings — or worse, an error for a modifier that was never real.

Meet Orchard

Orchard is Parsaa's live read of Apple's documentation. It grounds every Apple-related answer in real, current docs, so the Swift you get uses today's APIs instead of last year's memory.

It runs automatically. There is no prompt to remember, no setting to flip, no step to add. Ask anything about Apple frameworks and Orchard works in the background:

• It works on every Apple question, automatically.
• No extra prompts, no steps to remember.
• It names the deprecation and the modern fix.

Grounded in Apple's own docs

Orchard does not lean on third-party blogs or the model's memory. It reads Apple's primary sources — the same ones you would — and keeps up as they change:

• Apple's primary sources, not third-party blogs.
• Re-read as Apple publishes, not frozen at training time.
• Every public type, modifier, and deprecation status.

That covers the frameworks you actually reach for day to day — UIKit, SwiftUI, Foundation, SwiftData, and more — plus the language itself.

Current the day Apple ships

A new SDK lands every WWDC. Here is how Parsaa stays current without waiting for a retrain:

1. Apple ships. A new SDK lands at WWDC, with new APIs and fresh deprecations.
2. Orchard reads. It reads the new docs and sessions the day Apple publishes them.
3. You're current. Your Swift uses today's APIs, with the old ones flagged.

Zero retraining lag. New APIs the day Apple ships them.

It knows what replaced what

Apple renames and retires APIs every release. Orchard keeps the map and steers you to the current call instead of the one that throws a warning:

• UIAlertView → .alert()
• NavigationView → NavigationStack
• ObservableObject → @Observable
• .foregroundColor(_:) → .foregroundStyle(_:)
• .cornerRadius(_:) → .clipShape(.rect(...))
• .navigationBarTitle(_:) → .navigationTitle(_:)

And it follows the chain to the end: an old call that was replaced twice still lands on today's API.

Modernize a codebase, not just a snippet

Orchard is not only for one-off answers. Point Parsaa at your Swift and it modernizes the whole project:

1. Analyze. Scans your project and lists every deprecated API it finds, file by file.
2. Migrate. Rewrites the deprecated calls to their modern equivalents in place.
3. Review. Every change is approval-gated. You see the diff, and nothing lands without you.

Why it's different

• Always current — knows the newest WWDC SDK the day it ships.
• No hallucinated APIs — answers grounded in real docs, not the model's memory.
• Deprecation-aware — warns about old APIs and names the modern replacement.
• Grounded, not guessed — every answer traces back to Apple's own documentation.
• Fast — grounding lands in about a second, often instant.
• Multilingual — works whatever language you ask in.
• Zero setup — on by default for every Apple question.
• Never blocks you — if anything fails, you still get an answer.

Questions, answered

Does it slow Parsaa down? No. Grounding lands in about a second, and repeats are instant. Off-topic questions skip it entirely, so there is no cost when you are not asking about Apple.

What if the docs don't cover something? You still get an answer. Orchard adds grounding when it helps and stays out of the way when it cannot, so a gap never blocks you.

Do I have to turn it on? No setup. Orchard runs in the background on every Apple question, automatically.

Stop shipping last year's APIs

Orchard runs on every Apple question, no setup, and gives you current, grounded Swift. That is the difference between code that builds clean today and code that was already out of date when the model learned it.
