Xcode functionality not available in AppCode
The following Xcode features are not supported in AppCode:
User account and code signing management
WatchOS support (running and debugging)
Most of these features have zero documentation for file formats and do not have an open API, so implementing each of them in AppCode would require a substantial investment of time and effort. We will endeavor to implement some of them in the future, if and when we have the necessary resources. Stay tuned!
