SMART on FHIR

An iOS medication list app using SMART on FHIR via our iOS SMART on FHIR framework.

This example app runs out of the box against our sandbox server. To download and run you'll need Xcode 8 with Swift 3. Perform these steps:

1. Checkout the source code:

   git clone --recursive https://github.com/p2/SoF-MedList.git

2. Open the project file SoF-MedList.xcodeproj in Xcode 7+.

3. Select an iPhone simulator and press Run.

The master branch is currently on Swift 3.0 and the DSTU 2 (1.0.2) version of FHIR (version 2.8.0 of the SMART framework).
Check the develop branch for bleeding edge updates, if any, and the tags for older releases.

What's Happening?

This is a simple app based on Apple's master/detail view default code. There are two places where custom code performs interesting tasks:

App Delegate

In AppDelegate.swift we initialize a (lazy) handle to our SMART client (lines 18-23). Then, starting on line 39, there are 3 methods that the App delegate provides but mostly just forwards to the SMART client. The findMeds: method constructs a search for medication prescriptions for the selected patient and runs it against the server, as follows:

MedicationPrescription.search(["patient": id]).perform(...)

The last method is needed when choosing to use iOS's Safari instead of a built-in web view. It is implemented to intercept callbacks when the user returns from the browser after logging in and selecting a patient.

Master View Controller

The table view controller subclass MasterViewController.swift has a few tweaks to perform UI tasks, such as displaying the patient's name in the button top left. The most interesting part is the selectPatient: method which updates the UI accordingly, calls the App delegate's selectPatient: method and when it returns successfully continues to search for all of the patient's medication prescriptions, again using the App delegate and its findMeds: method. It displays an error on failure and on success reloads the table to show the names of the medications.
