This is still reproducible in Xcode 26.6 (17F113). In a basic SwiftUI project using #Preview, the Canvas is in Selectable mode and selecting a Text view works, but Command-Control-click shows only “Embed…”. “Show SwiftUI Inspector” is also absent from the Editor menu, the Inspector sidebar, and the Settings > Shortcuts command list. The current Landmarks tutorial still instructs users to choose it, so this appears to remain either an undocumented removal or a regression in Xcode 26.6.
