Ignore manual entries from Apple Health app as Data Source

Question

Hi I\'m writing a Fitness App which gets its Data from Apples Health app.

So far so good.

Problem: in Health app it is possible to make manually data entries

Answer 1

Swift 4:

let predicate = NSPredicate(format: "metadata.%K != YES", HKMetadataKeyWasUserEntered)

And if you have two predicates, useCompoundPredicate:

let compoundPredicate = NSCompoundPredicate(type: .and, subpredicates: [predicate1, predicate2])

Answer 2

Samples in HealthKit that were manually entered by the user will have have a YES value for the HKMetadataKeyWasUserEntered metadata key. To create a predicate that matches only samples that were not user-entered, you could do use the following:

[NSPredicate predicateWithFormat:@"metadata.%K != YES", HKMetadataKeyWasUserEntered];

Note that this must be formulated as value != YES because the value for the key could be YES, NO, or nil and nil implies NO.
