Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00804 | $0.00804 |
| Opus 5.5 | $0.00322 | $0.00322 |
| Sonnet 5.5 | $0.00161 | $0.00161 |
| Haiku 4.5 | $0.00080 | $0.00080 |
Grade A, and why
presets.dev swiftui.instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SwiftUI Copilot Instructions: State, Concurrency and Availability
Path-specific Copilot instructions for SwiftUI. They apply through applyTo and leave .github/copilot-instructions.md in place.
Updated for Swift 6.4, Nov 2026
Do not upgrade dependencies or the framework version unless the task asks.
Write for the Swift tools version and the deployment target in the project. Swift 6.4 adds async defer and cancellation shields, and Swift Build is the default build system on that line. Use those only when the toolchain is 6.4. Do not lower a deployment target, and do not mark a type @unchecked Sendable to quiet the compiler.
Project shape
A view is a function of state. @State owns view-local value. @Binding edits a parent's value. A reference model uses the Observation macro the project already adopted, @Observable, rather than a new ObservableObject in fresh code. Follow the existing choice if the app has not moved.
Views stay small. A feature folder holds the view, the model, and the tests when that is the local layout.
Concurrency
UI updates hop to the main actor. A view model that publishes to a view is @MainActor. The .task modifier is tied to the view: SwiftUI cancels it after the view disappears. A plain Task { } is unstructured. It keeps running if you drop the handle. Store that handle and call cancel() when the view goes away. Cancellation is cooperative: the work checks Task.isCancelled or Task.checkCancellation(). Do not capture self strongly in a task that outlives the view.
await a throwing call and surface the error. try? that becomes nil with no message hides a failure. Structured tasks have a parent. A detached task needs a reason. A cancellation shield is for the short cleanup that must finish, not for a whole network call you do not want to cancel.
Availability and data
An API newer than the deployment target is wrapped in if #available or marked with the availability attribute. Do not call it unconditionally because the simulator is new.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
