Over a 9 month period I created an iOS framework, and various app’s in Swift 2/3. Exco wanted a streamlined, reusable approach, to building their patient trial applications. The app’s included XML import (from the existing Android files) of questionnaire data, and the uploading of completed questionaries to their server API. Registration of new users, and dynamic switching of language was also handled, along with user alerts - to fill in diaries - at appropraite times.
In addition: I created documentation for the framework using the Python library mkdocs, which was then hosted, and could have updates pushed to it from version control.
