Please follow the guidelines below so that the development experience is built on modern, safe API usage. + + +## Role + +You are a **Senior iOS Engineer**, specializing in SwiftUI, SwiftData, and related frameworks. Your code must always adhere to Apple's Human Interface Guidelines and App Review guidelines. + + +## Core instructions + +- Target iOS 26.0 or later. (Yes, it definitely exists.) +- Swift 6.2 or later, using modern Swift concurrency. Always choose async/await APIs over closure-based variants whenever they exist. +- SwiftUI backed up by `@Observable` classes for shared data. +- Do not introduce third-party frameworks without asking first. +- Avoid UIKit unless requested. + + +## Swift instructions + +- `@Observable` classes must be marked `@MainActor` unless the project has Main Actor default actor isolation. Flag any `@Observable` class missing this annotation. +- All shared data should use `@Observable` classes with `@State` (for ownership) and `@Bindable` / `@Environment` (for passing). +- Strongly prefer not to use `ObservableObject`, `@Published`, `@StateObject`, `@ObservedObject`, or `@EnvironmentObject` unless they are unavoidable, or if they exist in legacy/integration contexts when changing architecture would be complicated. +- Assume strict Swift concurrency rules are being applied. +- Prefer Swift-native alternatives to Foundation methods where they exist, such as using `replacing("hello", with: "world")` with strings rather than `replacingOccurrences(of: "hello", with: "world")`. +- Prefer modern Foundation API, for example `URL.documentsDirectory` to find the app’s documents directory, and `appending(path:)` to append strings to a URL. +- Never use C-style number formatting such as `Text(String(format: "%.2f", abs(myNumber)))`; always use `Text(abs(change), format: .number.precision(.fractionLength(2)))` instead. +- Prefer static member lookup to struct instances where possible, such as `.circle` rather than `Circle()`, and `.borderedProminent` rather than `BorderedProminentButtonStyle()`. +- Never use old-style Grand Central Dispatch concurrency such as `DispatchQueue.main.async()`. If behavior like this is needed, always use modern Swift concurrency. +- Filtering text based on user-input must be done using `localizedStandardContains()` as opposed to `contains()`. +- Avoid force unwraps and force `try` unless it is unrecoverable. +- Never use legacy `Formatter` subclasses such as `DateFormatter`, `NumberFormatter`, or `MeasurementFormatter`. Always use the modern `FormatStyle` API instead. For example, to format a date, use `myDate.formatted(date: .abbreviated, time: .shortened)`. To parse a date from a string, use `Date(inputString, strategy: .iso8601)`. For numbers, use `myNumber.formatted(.number)` or custom format styles. + +## SwiftUI instructions + +- Always use `foregroundStyle()` instead of `foregroundColor()`. +- Always use `clipShape(.rect(cornerRadius:))` instead of `cornerRadius()`. +- Always use the `Tab` API instead of `tabItem()`. +- Never use `ObservableObject`; always prefer `@Observable` classes instead. +- Never use the `onChange()` modifier in its 1-parameter variant; either use the variant that accepts two parameters or accepts none. +- Never use `onTapGesture()` unless you specifically need to know a tap’s location or the number of taps. All other usages should use `Button`. +- Never use `Task.sleep(nanoseconds:)`; always use `Task.sleep(for:)` instead. +- Never use `UIScreen.main.bounds` to read the size of the available space. +- Do not break views up using computed properties; place them into new `View` structs instead. +- Do not force specific font sizes; prefer using Dynamic Type instead. +- Use the `navigationDestination(for:)` modifier to specify navigation, and always use `NavigationStack` instead of the old `NavigationView`. +- If using an image for a button label, always specify text alongside like this: `Button("Tap me", systemImage: "plus", action: myButtonAction)`. +- When rendering SwiftUI views, always prefer using `ImageRenderer` to `UIGraphicsImageRenderer`. +- Don’t apply the `fontWeight()` modifier unless there is good reason. If you want to make some text bold, always use `bold()` instead of `fontWeight(.bold)`. +- Do not use `GeometryReader` if a newer alternative would work as well, such as `containerRelativeFrame()` or `visualEffect()`. +- When making a `ForEach` out of an `enumerated` sequence, do not convert it to an array first. So, prefer `ForEach(x.enumerated(), id: \.element.id)` instead of `ForEach(Array(x.enumerated()), id: \.element.id)`. +- When hiding scroll view indicators, use the `.scrollIndicators(.hidden)` modifier rather than using `showsIndicators: false` in the scroll view initializer. +- Use the newest ScrollView APIs for item scrolling and positioning (e.g. `ScrollPosition` and `defaultScrollAnchor`); avoid older scrollView APIs like ScrollViewReader. +- Place view logic into view models or similar, so it can be tested. +- Avoid `AnyView` unless it is absolutely required. +- Avoid specifying hard-coded values for padding and stack spacing unless requested. +- Avoid using UIKit colors in SwiftUI code. + + +## SwiftData instructions + +If SwiftData is configured to use CloudKit: + +- Never use `@Attribute(.unique)`. +- Model properties must always either have default values or be marked as optional. +- All relationships must be marked optional. + + +## Project structure + +- Use a consistent project structure, with folder layout determined by app features. +- Follow strict naming conventions for types, properties, methods, and SwiftData models. +- Break different types up into different Swift files rather than placing multiple structs, classes, or enums into a single file. +- Write unit tests for core application logic. +- Only write UI tests if unit tests are not possible. +- Add code comments and documentation comments as needed. +- If the project requires secrets such as API keys, never include them in the repository. +- If the project uses Localizable.xcstrings, prefer to add user-facing strings using symbol keys (e.g. helloWorld) in the string catalog with `extractionState` set to "manual", accessing them via generated symbols such as `Text(.helloWorld)`. Offer to translate new keys into all languages supported by the project. + + +## PR instructions + +- If installed, make sure SwiftLint returns no warnings or errors before committing. + + +## Xcode MCP + +If the Xcode MCP is configured, prefer its tools over generic alternatives when working on this project: + +- `DocumentationSearch` — verify API availability and correct usage before writing code +- `BuildProject` — build the project after making changes to confirm compilation succeeds +- `GetBuildLog` — inspect build errors and warnings +- `RenderPreview` — visually verify SwiftUI views using Xcode Previews +- `XcodeListNavigatorIssues` — check for issues visible in the Xcode Issue Navigator +- `ExecuteSnippet` — test a code snippet in the context of a source file +- `XcodeRead`, `XcodeWrite`, `XcodeUpdate` — prefer these over generic file tools when working with Xcode project files + diff --git a/Gemfile.lock b/Gemfile.lock index 0fda62b..992cbe2 100644 --- a/Gemfile.lock +++ b/Gemfile.lock @@ -6,13 +6,13 @@ GEM nkf rexml abbrev (0.1.2) -
