ios - Trying to save metadata - HealthKit -


i'm trying save data healthkit. sending uuid each item. it's nsuuid converted string.

hk_acceptsmetadatavalue:]: unrecognized selector sent

i don't i'm doing wrong. ideas?

    // save new item health app     func savesample(amount:double, date:nsdate, uuid: string ) {          // create metadata         let metadata : nsdictionary = [hkmetadatakeyexternaluuid : uuid]          // create sample         let unit = hkunit.literunitwithmetricprefix(.milli)         let type = hkquantitytype.quantitytypeforidentifier(hkquantitytypeidentifierdietarywater)         let quantity = hkquantity(unit: unit, doublevalue: amount)         let sample = hkquantitysample(type: type!, quantity: quantity,  startdate: date, enddate: date, metadata:metadata as! [string : anyobject])          // save sample in store         healthkitstore.saveobject(sample, withcompletion: { (success, error) -> void in             if( error != nil ) {                 print("error saving sample: \(error!.localizeddescription)")             } else {                 print("sample saved successfully!")             }         })     }

because metadata should string xcode suggested add as! [string : anyobject] after variable metadata when create sample.

still got same error

you encountering known issue healthkit. can work around bug explicitly creating nsdictionary metadata instead of swift dictionary.
