swiftui-pro（SwiftUI 专业版）

Review Swift and SwiftUI code for correctness, modern API usage, and adherence to project conventions. Report only genuine problems - do not nitpick or invent issues.

Review process:

1. Check for deprecated API using references/api.md.
2. Check that views, modifiers, and animations have been written optimally using references/views.md.
3. Validate that data flow is configured correctly using references/data.md.
4. Ensure navigation is updated and performant using references/navigation.md.
5. Ensure the code uses designs that are accessible and compliant with Apple’s Human Interface Guidelines using references/design.md.
6. Validate accessibility compliance including Dynamic Type, VoiceOver, and Reduce Motion using references/accessibility.md.
7. Ensure the code is able to run efficiently using references/performance.md.
8. Quick validation of Swift code using references/swift.md.
9. Final code hygiene check using references/hygiene.md.

If doing a partial review, load only the relevant reference files.

Core Instructions

• iOS 26 exists, and is the default deployment target for new apps.
• Target Swift 6.2 or later, using modern Swift concurrency.
• As a SwiftUI developer, the user will want to avoid UIKit unless requested.
• Do not introduce third-party frameworks without asking first.
• Break different types up into different Swift files rather than placing multiple structs, classes, or enums into a single file.
• Use a consistent project structure, with folder layout determined by app features.

Output Format

Organize findings by file. For each issue:

1. State the file and relevant line(s).
2. Name the rule being violated (e.g., "Use foregroundStyle() instead of foregroundColor()").
3. Show a brief before/after code fix.

Skip files with no issues. End with a prioritized summary of the most impactful changes to make first.

Example output:

ContentView.swift

Line 12: Use foregroundStyle() instead of foregroundColor().

// Before
Text("Hello").foregroundColor(.red)

// After
Text("Hello").foregroundStyle(.red)

Line 24: Icon-only button is bad for VoiceOver - add a text label.

// Before
Button(action: addUser) {
    Image(systemName: "plus")
}

// After
Button("Add User", systemImage: "plus", action: addUser)

Line 31: Avoid Binding(get:set:) in view body - use @State with onChange() instead.

// Before
TextField("Username", text: Binding(
    get: { model.username },
    set: { model.username = $0; model.save() }
))

// After
TextField("Username", text: $model.username)
    .onChange(of: model.username) {
        model.save()
    }

Summary

1. Accessibility (high): The add button on line 24 is invisible to VoiceOver.
2. Deprecated API (medium): foregroundColor() on line 12 should be foregroundStyle().
3. Data flow (medium): The manual binding on line 31 is fragile and harder to maintain.

End of example.
