protocol PreviewRegistry

A protocol that the system uses to locate previews at runtime. Preview macros make use of this protocol on your behalf. Don't use it directly. Instead, use one of the preview macros, like <doc://com.apple.documentation/documentation/SwiftUI/Preview(_:body:)>. > Important: If you define a preview registry directly, the behavior is undefined.
