Swift-SMART is a full client implementation of the 🔥 FHIR specification written in Swift.

It contains classes representing all default profiles (i.e. data models) and provides an implementation of Client and Server objects to communicate with a FHIR server. Authorization with servers protected by OAuth2 is supported out of the box.

QuickStart

To get you off the ground quickly, here's how you instantiate a Client handle, have the user login and select a patient, then fetch that patient's MedicationPrescription resources:

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
            }
        }
    }
}
