Is there a CarPlay Simulator available in Xcode or from another source? I would like to view if my current app has any interaction with it such as how notifications received from my app are displaying.
Actually there is a CarPlay "External Display" that can be enabled, for it to show up you simply need to type in this command in a Terminal window:
defaults write com.apple.iphonesimulator CarPlay -bool YES
Then shutdown and restart the Simulator.
