Fetching More Docs
- Search this skill's local
.mdfiles first. - If the topic is not here, check the other installed Apple skills you have available by their names, descriptions, or
SKILL.mdfrontmatter, then grep their local files. This is faster and uses less context than fetching new docs from the internet. - If no installed skill has the page, use the relevant documentation path from
uikit-overview.mdwith thesosumi.aiMarkdown mirror. For example,/documentation/uikit/uiviewmaps tohttps://sosumi.ai/documentation/uikit/uiview.
Some UIKit-adjacent APIs live in other frameworks. For example, UIHostingController is documented under SwiftUI.
