# identifier

The value from the FHIR resource’s id field.

## Declaration

```swift
var identifier: String { get }
```

## Mentioned in

Accessing Health Records

## Discussion

Discussion This identifier is only unique for a particular resource type from a given source. To uniquely identify a FHIR resource, you must compare the identifier and resourceType properties from the HKFHIRResource object and the bundleIdentifier property from the clinical record’s source.
