digraph method_choice {
"Check Package.swift platforms" [shape=box];
"iOS only?" [shape=diamond];
"Use xcodebuild docbuild" [shape=box, style=filled, fillcolor=lightblue];
"Use swift-docc-plugin" [shape=box];
"Check Package.swift platforms" -> "iOS only?";
"iOS only?" -> "Use xcodebuild docbuild" [label=".iOS only"];
"iOS only?" -> "Use swift-docc-plugin" [label="includes .macOS"];
}
Why? swift package generate-documentation builds for macOS. iOS-only packages fail with "no such module 'UIKit'".

| Error | Fix |
|---|---|
| "no such module 'UIKit'" | iOS-only package: use xcodebuild docbuild |
| 404 at root URL | Add redirect index.html step |
| Empty documentation | Ensure types are public |
| Wrong URL case | Target in URL is always lowercase |
| Pages not deploying | Enable GitHub Actions as Pages source |
Custom docs: Add Sources/TARGET_NAME/Documentation.docc/ with landing page and articles.
