searchbar（searchbar 开发）

SearchBar Skill

Overview

This skill provides expert guidance on SearchBar, a powerful and highly customizable SwiftUI component for creating native-feeling search experiences across iOS, iPadOS, macOS, and visionOS. It bridges the gap between UISearchBar (iOS/visionOS) and native SwiftUI views (macOS), offering a unified API for styling, behavior, and advanced features like search tokens and dynamic suggestions.

Agent Behavior (Follow These Rules)

1. Identify Platform Targets: SearchBar behaves slightly differently on iOS/visionOS (wraps UISearchBar) vs. macOS (custom SwiftUI). Always check or ask for the target platform to provide accurate advice (e.g., specific material effects or token behaviors).
2. Prioritize Modifiers: Direct users to the relevant SearchBar modifiers (e.g., .searchBarStyle, .searchBarSuggestions) rather than suggesting they build custom views from scratch.
3. Clarify Availability: Explicitly mention version requirements (iOS 14+, iOS 16+ for tokens/suggestions) when discussing advanced features.
4. Emphasize Localization: Remind users that SearchBar is fully localized and adapts to system languages automatically.
5. Contextual Examples: Provide concise code snippets that illustrate the recommended usage within a View, often with a binding to @State for text and tokens.
6. Highlight Cross-Platform: When possible, remind users of SearchBar's cross-platform consistency and how to handle platform-specific differences using #if os(...) directives if necessary (though the library handles most internally).

Project Settings

• Deployment Targets: iOS 14.0+, iPadOS 14.0+, macOS 11.0+, visionOS 1.0+.
• Advanced Features: Tokens and Suggestions require iOS 16.0+, iPadOS 16.0+, visionOS 1.0+. (Suggestions also on macOS 15.0+).
• Swift Version: Swift 5.9+.

Quick Decision Tree

1. Setting up a basic search bar?

* Basic init and setup → references/SearchBar.md

1. Customizing appearance?

* Changing colors, shape (capsule/rounded) → references/SearchBarStyle.md * Using "Glass" or "Solid" materials → references/SearchBarStyle.md * Changing the size/scale → references/SearchBarStyle.md * Custom icon → references/SearchBarModifiers.md (.searchBarIconView)

1. Configuring behavior?

* Showing/Hiding Cancel or Clear buttons → references/SearchBarDisplayModes.md * Handling events (begin/end editing, clear, cancel) → references/SearchBarModifiers.md * Focus management → references/SearchBarModifiers.md (.searchBarIsFocused)

1. Using advanced search features (iOS 16+/visionOS)?

* Adding filter tokens (capsules) → references/SearchBarData.md * Showing search suggestions → references/SearchBarData.md * Enabling automatic suggestion filtering → references/SearchBarData.md

Triage-First Playbook

• "My search bar looks different on macOS."

* Explain that macOS uses a pure SwiftUI implementation while iOS uses UISearchBar. Styling is consistent but underlying implementation differs.

• "Tokens/Suggestions are not showing up."

* Verify the deployment target is iOS 16.0+ or visionOS 1.0+. * Ensure the binding to tokens/suggestions is active and populated.

• "How do I change the background color?"

* Use .searchBarStyle(..., backgroundColor: .red). See references/SearchBarStyle.md.

• "I want to hide the cancel button."

* Use .searchBarCancelButtonDisplayMode(.never). See references/SearchBarDisplayModes.md.

• "How do I make the search bar glass/transparent?"

* Use .searchBarMaterial(.glass). Note platform/version restrictions (iOS 26+). See references/SearchBarStyle.md.

Core Patterns Reference

Basic Setup

SearchBar(text: $text, prompt: "Search...")
    .searchBarStyle(.rounded)

Advanced Styling

SearchBar(text: $text)
    .searchBarStyle(.capsule, textColor: .white, tint: .blue, backgroundColor: .black.opacity(0.8))
    .searchBarMaterial(.glass) // iOS 26+ (Experimental/Future)

Tokens & Suggestions

SearchBar(text: $text)
    .searchBarCurrentTokens($tokens)
    .searchBarSuggestions($suggestions)
    .searchBarEnableAutomaticSuggestionsFiltering(true)

Event Handling

SearchBar(text: $text)
    .searchBarBeginEditingAction { print("Started") }
    .searchBarEndEditingAction { print("Ended") }
    .searchBarCancelButtonAction { print("Cancelled") }

Integration Quick Guide

SearchBar is integrated via Swift Package Manager.

1. Add Package Dependency: In Xcode, go to File > Add Package Dependency and enter https://github.com/SzpakKamil/SearchBar.git.
2. Import: import SearchBar in your Swift files.
3. Deployment Targets: Ensure your project targets iOS 14.0+, macOS 11.0+, visionOS 1.0+.

For detailed setup, see references/SearchBar.md.
