Tempelhof Reviews
This app allows you to browse reviews on The Berlin Tempelhof Airport posted on Get Your Guide.
Using The App
There are two screens in the app, the main reviews list screen where a summary of different reviews can be seen and a details screen. On tapping on any of the cells on the list, a details screen can be seen that allows a more in depth look at the review.
Technical Implementation
The app uses the MVVM-C architecture. The coordinator creates an instance of the ReviewViewController and returns it to the App Delegate where it is set as the root view controller of a navigation controller which itself becomes the root of window. Each view controller is injected with a view model which handles fetching and providing data to the view controller. The decision to avoid using a storyboard is in appreciation of the fact that storyboards are difficult to manage in a shared development team.
The fetching is done is a paginated manner. Each request fetches 10 review objects and a new request is triggered everytime the table view is scrolled to its bottom.
