Declaration
var metadata: [String : Any]? { get }Discussion
The metadata dictionary contains extra information describing this object. The dictionary’s keys are all strings. The values can be strings, numbers, or dates. For a complete list of predefined metadata keys, see Metadata Keys.
Using predefined keys helps facilitate sharing data between apps; however, you’re also encouraged to create your own, custom keys as needed to extend a HealthKit object’s capabilities.
