Swift-SMART is a full client implementation of the 🔥FHIR specification for building apps that interact with healthcare data through SMART on FHIR. Written in Swift it is compatible with iOS 8 and OS X 10.9 and newer and requires Xcode 6 or newer.

Versioning

Due to the complications of combining two volatile technologies, here's an overview of which version numbers use which Swift and FHIR versions. The master branch should always compile and is on (point releases of) these main versions. See the develop branch or specific feature/x branches for new Swift or FHIR versions, and check the tags.

Version	Swift Version	FHIR Version
1.0	1.2	DSTU 2 (May 2015, 0.5.0.5149)
0.2	1.1	DSTU 2 (May 2015, 0.5.0.5149)
0.1	1.0	DSTU 1 (0.0.81.2382)

QuickStart

See the programming guide for more code examples and details.

import SMART

// create the client
let smart = Client(
    baseURL: "https://fhir-api-dstu2.smarthealthit.org",
    settings: [
        "client_id": "my_mobile_app",
        "redirect": "smartapp://callback",    // must be registered
    ]
)

// authorize, then search for prescriptions
smart.authorize() { patient, error in
    if nil != error || nil == patient {
        // report error
    }
    else {
        MedicationPrescription.search(["patient": patient!.id])
        .perform(smart.server) { bundle, error in
            if nil != error {
                // report error
            }
            else {
                var meds = [MedicationPrescription]()
                if let entries = bundle?.entry {
                    for entry in entries {
                        if let med = entry.resource as? MedicationPrescription {
                            meds.append(med)
                        }
                    }
                }
                
                // now `meds` holds all known patient prescriptions
            }
        }
    }
}
