Item
Native item composition, package imports, and editable Swift source.

Use it
Import SwiftCN to use CNItem directly. This complete example also runs in the native component gallery.
import SwiftUI
import SwiftCN
struct ItemExample: View {
var body: some View {
VStack(alignment: .leading, spacing: 12) {
CNItem {
Image(systemName: "folder").accessibilityHidden(true)
CNItemContent { CNItemTitle("Design system"); CNItemDescription("Shared native components") }
Spacer()
CNItemActions { CNButton("Open", variant: .outline, action: {}) }
}
}
}
}Native behavior
Compose leading media, CNItemContent, title, description, and CNItemActions in a native row. The row aligns content at its center. Place interactive content in native controls to define activation semantics. CNItemActions keeps the same controls in a row or a vertical stack, based on their natural widths and the available space. It uses the shared native adaptive action layout.
Style and compose
Visual recipes use .tw classes. Append classes: to override a recipe locally, or change the recipe in TWGlobalRules.named for your subtree. Native layout and interaction modifiers remain SwiftUI APIs. For control colors, append cn-tint-[primary], another theme token, or an interpolated Color.
Motion recipes are editable too: control-motion uses a 150 ms smooth response, disclosure-motion uses a 250 ms spring, and feedback-motion uses a 200 ms smooth response. Set a recipe to animate-none in your global rules to turn it off. Presets respect Reduce Motion. Static components stay still; native scrolling, drag tracking, and platform presentation keep their own gestures.
Action groups and card, dialog, and questionnaire footers stack when their content does not fit. The native layout preserves the same child controls during this change.
View builders preserve native child content. Native Button roles, labels, keyboard shortcuts, submit actions, and presentation modifiers still work. A string recipe does not replace a native control API or a typed chart mark.
Own the source
Copy the complete file below into your app alongside import SwiftCN. The file contains related composable parts from the same family. Its dependencies use public package APIs, so copied and imported components can coexist.
To own the styling engine too, download the complete source bundle. It contains every component, the .tw engine, its recipes, and the MIT license. Keep those files in one module and remove import SwiftCN from the usage example.
