The metadata dictionary contains extra information describing all the samples created by the builder. The dictionary’s keys are all strings. The values may be strings, numbers, or date objects. For a complete list of predefined metadata keys, see Metadata Keys.
Using predefined keys helps facilitate sharing data between apps; however, you are also encouraged to create your own, custom keys as needed to extend the samples' capabilities..
The date when the sample ends. If
nil, the builder uses the latest end date from the contained quantities.
The sample builder returns an

A completion handler, called by the builder after it creates the samples.

The samples returned by the builder, or

If an error occurs, this contains an object that describes the error. Otherwise, it is
finish after inserting all the quantities for the series. The series builder then creates one or more samples to represent the series, saves the samples to the HealthKit store, and then passes them to the completion handler.
