GR8Conf EU is the biggest conference in Europe around the Groovy, Grails, Gradle ecosystem. An iOS app was developed in Swift. The app loaded a Plist file with information about the conference. It displayed the conference schedule with detailed information about the talks. The apps displayed information about the sponsors, how to reach the conference venue etc.
The property list file was generated with a Groovy script which connected to the GR8Conf API.
I collaborated as well with the Android App of the conference with a pull request which allowed to change events within the app.
