I tried to access the CPWindow that is attached to templateApplicationScene inside the following callback: func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) But the debugger consistently prints <uninitialized> when examining the object. Here a gist - https://gist.github.com/sts2055/6c6a65d9253b14487deaa6f16e206b45 that includes a screenshot to further illustrate this. The description of the CPWindow also reads: Navigation apps use a window to render their maps, and CarPlay provides one via the scene delegate’s templateApplicationScene(:didConnect:to:)method. For all other categories of apps, you use templates exclusively to draw your user interface, and your scene delegate must implement templateApplicationScene(:didConnect:)instead. The app I'm working on is a CarPlay parking app. Is the description of CPWindow not up to date? I'm using Xcode Version 12.0.1 (12A7300)

I watched the video but it doesn't make any reference to Window access or how to display a spinner in Templates like CPPointOfInterestTemplate. The only Template that seems to support spinners without requiring access to CPWindow is CPListTemplate (as shown in the video).

Same issue here. It seems as if appstoreconnect currently attributes incorrect UUIDs to dsyms generated from bitcode enabled build archives. One way to solve this (and the only one I know of) is to rename the internal UUID of the dsym that corresponds to the binary image of the stack frame that isn't symbolicated. In most cases this is your app's binary image. What you can do is either manually rename it using the already mentioned excellent article on medium, or automatically using the following tool: https://github.com/schmittsfn/dsymrename You have to be absolutely sure, however, that the dsym you are renaming corresponds to the build Crashlytics is requesting (for bitcode builds these are the dsyms generated on appstoreconnect)! Failure to do so will most likely lead to the warning on Crashlytics being silenced and the stack frame being unintelligible.
