Making snapshots without host application for swift package

[agruchala]

I added snapshot testing to swift package test target, package tests run without host application. On snapshots I see background but I can't make them render text. Any ideas how to make it happen? I'm testing SwiftUI views.

It's my understanding that this is a limitation of Swift Packages, not SnapshotTesting. This is because Swift Packages cannot contain an entire application. Applications require an Xcode project, and Xcode projects cannot be held inside a Swift Package.

Snapshots of individual SwiftUI Views can be made in a Swift Package, but if your snapshot requires a host application then you need to make it in an Xcode project. (Also, when making a snapshot that requires an application, don't forget to set drawHierarchyInKeyWindow to true. See

swift-snapshot-testing/Sources/SnapshotTesting/Snapshotting/SwiftUIView.swift

Line 29 in d1082c4

/// - drawHierarchyInKeyWindow: Utilize the simulator's key window in order to render
