We created a custom Timeline control to visualize the current status of a parcel on the time axis. The application is able to show a detailed statue of a parcel.
To interact with the server-side application we used the REST API implemented on Alamofire in iOS and on Retrofit 2 in Android.
Initially, the server-side application sent the data in an incorrectly formed XML format. To fix it we developed its own XML parser to process it. After the server was updated on the side of the customer and the mobile app started to receive data in JSON format. To work with JSON, we used Swift built-in toolkit and GSON library for Android.
