How Do You Know Whether or Not SwiftUI Previews and Preview Content Are Excluded From App Store Builds?
Read OriginalThis technical article investigates a concerning behavior in Xcode's handling of SwiftUI previews. The author details how preview source code and development assets (like those in a 'Preview Content' directory) are not reliably excluded from App Store builds, potentially causing archive failures. It explains the conditions under which this occurs and suggests workarounds, primarily wrapping preview code in #if DEBUG compilation condition checks to ensure it's omitted from release builds.
