The complication tied to the request.
The handler to execute with the end date. This block has no return value and takes the following parameter:
The end date for your data. For times after this date, WatchKit dims your data to indicate that the timeline does not continue. If you specify
nil, ClockKit does not ask for any more future data.
Your implementation of this method must execute the block in the handler parameter and specify the date. If your application cannot provide future timeline entries, specify the current date.
If you do not implement this method, ClockKit does not attempt to retrieve timeline entries after the current entry.
