iOS 26 Research Assistant

Purpose

Compensate for Claude's January 2025 knowledge cutoff by actively searching Apple's official iOS 26 documentation before making claims about iOS 26 APIs, frameworks, or features.

Core Principle: Never state iOS 26 facts without verification. Always search official Apple documentation first.

When to Use This Skill

Auto-Activate (Mandatory)

Trigger automatically when:

• About to make statements like "iOS 26 has...", "In iOS 26...", "iOS 26 supports..."
• Suggesting iOS 26-specific APIs (.glassEffect(), GlassEffectContainer, etc.)
• Implementing iOS 26 features
• Answering "Does iOS 26 support X?" questions
• Explaining iOS 26 breaking changes or new patterns
• Referencing WWDC 2025 sessions

Manual Invocation

User explicitly requests:

• "Research iOS 26 [feature]"
• "Verify iOS 26 [API]"
• "What's new in iOS 26?"
• "Find iOS 26 documentation for X"
• "Check Apple docs for Y"
• "Is this correct for iOS 26?"

DO NOT Use

Skip this skill for:

• General Swift 6 language features (unless iOS 26-specific)
• Cross-platform Swift code not tied to iOS APIs
• Historical iOS versions (iOS 25 and earlier)
• Third-party frameworks or libraries
• General programming concepts

Example:

According to Apple's iOS 26 documentation [Verified-Apple-iOS26], the
`.glassEffect()` modifier accepts a `Glass` parameter that can be customized
with `.tint()` and `.interactive()` modifiers.

Source: https://developer.apple.com/documentation/swiftui/view/glasseffect

Example from docs:
```swift
Text("Hello, World!")
    .glassEffect(.regular.tint(.orange).interactive())

## Example Workflows

### Example 1: Verify Liquid Glass API

**User asks:** "How do I use Liquid Glass in iOS 26?"

**Workflow:**

1. Detect iOS 26 claim needed
2. Search: mcp__apple-rag-mcp__search("iOS 26 Liquid Glass glassEffect API")
3. Results found with code examples
4. Tag as [Verified-Apple-iOS26]
5. Cite: developer.apple.com/documentation/swiftui/view/glasseffect
6. Provide verified answer with examples from docs

**Response:**

According to Apple's iOS 26 documentation [Verified-Apple-iOS26], you use the .glassEffect() modifier to apply Liquid Glass effects:

Basic usage:

Text("Hello, World!")
    .font(.title)
    .padding()
    .glassEffect()

With tinting and interactivity:

Text("Hello, World!")
    .glassEffect(.regular.tint(.orange).interactive())

Source: https://developer.apple.com/documentation/swiftui/view/glasseffect

### Example 2: Check SwiftData Changes

**User asks:** "Are there SwiftData improvements in iOS 26?"

**Workflow:**

1. Detect iOS 26 claim needed
2. Search: mcp__apple-rag-mcp__search("SwiftData iOS 26 new features 2025")
3. Check: mcp__sosumi__searchAppleDocumentation("iOS 26 release notes SwiftData")
4. If found: Tag [Verified-Apple-iOS26] + cite
5. If not found: Tag [Searched-Not-Found] + acknowledge

### Example 3: Feature Not Found

**User asks:** "Does iOS 26 have built-in AI voice synthesis?"

**Workflow:**

1. Search all tiers for "iOS 26 AI voice synthesis"
2. No results in Apple docs
3. Tag as [Searched-Not-Found]
4. State clearly: "I searched Apple's iOS 26 documentation but could not find information about built-in AI voice synthesis. This feature may not exist, or documentation may not be available yet."

## Integration with Project Workflows

### Pre-Code Verification

Before suggesting iOS 26 code:
1. Search for API documentation
2. Verify syntax and parameters
3. Include verified code examples from docs
4. Tag all iOS 26-specific code

### During Implementation

When implementing iOS 26 features:
1. Reference official documentation
2. Link to WWDC sessions
3. Note any beta limitations
4. Verify iOS 26.0+ availability

### Code Review

When reviewing iOS 26 code:
1. Verify APIs used are documented
2. Check for deprecated patterns
3. Confirm iOS 26-only usage (no fallbacks)
4. Validate against Apple guidelines

## Performance Considerations

### Search Timeouts

- Tier 1 (Apple RAG): 10 seconds max
- Tier 2 (Sosumi): 10 seconds max
- Tier 3 (Fetch): 15 seconds max
- Tier 4 (Web Search): 10 seconds max

**Total maximum search time:** ~45 seconds for full multi-tier search

### Optimization Strategies

1. **Cache Common Searches**
   - `.glassEffect()` API
   - `GlassEffectContainer` usage
   - Common iOS 26 patterns

2. **Parallel Searches**
   - Run Tier 1 and Tier 2 in parallel when appropriate
   - Aggregate results for comprehensive answers

3. **Skip Unnecessary Searches**
   - Don't search for general Swift concepts
   - Skip for pre-iOS 26 APIs
   - Avoid duplicate searches in same conversation

## Success Metrics

This skill is successful when:

- [ ] All iOS 26 claims are tagged with verification status
- [ ] Source URLs provided for verified claims
- [ ] [Searched-Not-Found] used when docs not available
- [ ] Reduced incorrect iOS 26 API suggestions to zero
- [ ] WWDC25 sessions referenced appropriately
- [ ] Users can verify claims independently via provided URLs

## Maintenance

**Update triggers:**
- iOS 26.1+ releases with new documentation
- WWDC 2025 session additions
- Release notes updates
- Beta to stable API changes

**Review quarterly:**
- Search query patterns
- Tag usage accuracy
- Source citation completeness
- User feedback on accuracy

## Notes

- This skill is specific to iOS 26+ documentation verification
- For general Swift 6 questions unrelated to iOS, skip this skill
- Always prefer official Apple documentation over inferences
- When in doubt, search and tag appropriately
- Better to say "[Searched-Not-Found]" than guess incorrectly
