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 release. Requires the Sosumi MCP to be available.

Update SwiftUI APIs

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

Compare findings against existing entries. Categorize results:

New deprecations: APIs not yet documented in
```
latest-apis.md
```
Corrections: Existing entries that need updating (wrong version, better replacement available)
New version segments: If a new iOS version introduces deprecations, add a new section

5. Update latest-apis.md

Follow the established format exactly. Each entry must include:

Section placement -- place under the correct version segment:

"Always Use (iOS 15+)" for long-deprecated APIs
"When Targeting iOS 16+" / "17+" / "18+" / "26+" for version-gated changes

Entry format:

markdown

**Always use `modernAPI()` instead of `deprecatedAPI()`.**

\```swift
// Modern
View()
    .modernAPI()

// Deprecated
View()
    .deprecatedAPI()
\```

Quick Lookup Table -- add a row at the bottom of the file:

markdown

| `deprecatedAPI()` | `modernAPI()` | iOS XX+ |

Keep the attribution line at the top of the file:

Based on a comparison of Apple's documentation using the Sosumi MCP, we found the latest recommended APIs to use.

6. Open a pull request

Create a branch from
```
main
```
named
```
update/latest-apis-YYYY-MM
```
(use current year and month).

Sosumi MCP Tool Reference

Tool	Parameters	Returns
`searchAppleDocumentation`	`query` (string)	JSON with `results[]` containing `title` , `url` , `description` , `breadcrumbs` , `tags` , `type`
`fetchAppleDocumentation`	`path` (string, e.g. `/documentation/swiftui/view/foregroundstyle(_:)` )	Markdown documentation content
`fetchAppleVideoTranscript`	`path` (string, e.g. `/videos/play/wwdc2025/10133` )	Markdown transcript
`fetchExternalDocumentation`	`url` (string, full https URL)	Markdown documentation content

Tips

Start broad with
```
searchAppleDocumentation
```
queries, then drill into specific paths with
```
fetchAppleDocumentation
```
.
Apple's deprecation docs typically say "Deprecated" in the page and link to the replacement.
WWDC "What's new in SwiftUI" sessions are the best source for newly introduced replacements.
When unsure about the exact iOS version for a deprecation, verify by checking the "Availability" section in the fetched documentation.
If an API is deprecated but no direct replacement exists, note this rather than suggesting an incorrect alternative.
