Get the most recent weight sample.
On success, the callback function will be provided with a weight object containing the weight value, and the startDate and endDate of the weight sample. Note: startDate and endDate will be the same as weight samples are saved at a specific point in time.
Example input options:
let options = {
unit: 'pound',
Call the method:
AppleHealthKit.getLatestWeight(options, (err: string, results: HealthValue) => {
if (err) {
console.log('error getting latest weight: ', err)
Example output:
"value": 200,
"startDate": "2016-07-08T12:00:00.000-0400",
"endDate": "2016-07-08T12:00:00.000-0400"
