Update SwiftUI APIs

When to Use

Use this skill when you need scan Apple's SwiftUI documentation for deprecated APIs and update the SwiftUI Expert Skill with modern replacements. Use when asked to "update latest APIs", "refresh deprecated SwiftUI APIs", "check for new SwiftUI deprecations", "scan for API changes", or after a new iOS/Xcode...

Systematically scan Apple's developer documentation via the Sosumi MCP, identify deprecated SwiftUI APIs and their modern replacements, and update swiftui-expert-skill/references/latest-apis.md.

Prerequisites

Sosumi MCP must be enabled and available (provides searchAppleDocumentation, fetchAppleDocumentation, fetchAppleVideoTranscript, fetchExternalDocumentation)
Write access to this repository (or a fork)

Workflow

1. Understand current coverage

Read swiftui-expert-skill/references/latest-apis.md to understand:

Which deprecated-to-modern transitions are already documented
The version segments in use (iOS 15+, 16+, 17+, 18+, 26+)
The Quick Lookup Table at the bottom

2. Load the scan manifest

Read references/scan-manifest.md (relative to this skill). It contains the categorized list of API areas, documentation paths, search queries, and WWDC video paths to scan.

3. Scan Apple documentation

For each category in the manifest:

Call searchAppleDocumentation with the listed queries to discover relevant pages.
Call fetchAppleDocumentation with specific documentation paths to get full API details.
Look for deprecation notices, "Deprecated" labels, and "Use ... instead" guidance.
Note the iOS version where the modern replacement became available.
Optionally call fetchAppleVideoTranscript for WWDC sessions that announce API changes.

Batch related searches together for efficiency. Focus on finding new deprecations not yet in latest-apis.md.

4. Compare and identify changes
