Hi! I'm participating in the Swift Student Developer competition this year, which requires developers to present a Swift Playground to Apple. I'm used to making normal Xcode projects, and am having trouble finding a Swift Playgrounds version of the Copy Bundle Resources build phase (I don't think it is possible to edit build phases in a Swift Playground). I created a '.usdz' file from a 3D model I designed using Reality Converter and added it to the root of my Swift Playground project. I access the file programmatically from the App Bundle like so (fileName is a non-nullable String): guard let path = Bundle.main.path(forResource: fileName, ofType: "usdz") else { fatalError("Couldn't find the USDZ file.") } At runtime, this throws the Couldn't find the USDZ file error, as the file isn't being copied to the App Bundle. In a normal Xcode project, according to this StackOverflow question, I can get xcodebuild to copy my file over by specifying it in the Copy Bundle Resources build phase, however, in a Swift Playground (required by Apple), I am restricted from modifying Xcode's buildphases (the option is not present when clicking on the default target - the only options are General, Signing & Capabilites and Package Dependencies). How can I ensure that resources are copied over to the App Bundle at buildtime in a Swift Playground? If this is not possible, are there any other options besides using the Bundle.main.path API for accessing the USDZ file (to load a QuickLook preview) at runtime?
