You're given a small app that fetches images from Flickr (http://www.flickr.com) and displays them in a grid.

The app has a small problem where sometimes the images don't show up or the user has to tap on the display first before the images show up.

You have the following tasks:

1. Fix this bug.

2. Since the source code doesn't contain any data model objects, you need to introdude them.

3. Implement a feature, where clicking on a thumbnail opens the image in a full screen view and shows the image name.

4. Write unit tests for the data model object(s).

Notes:

• Language: Objective-C for task #1
• Language: Swift for task #2, #3, #4 (Unit tests)
• Use GIT for versioning
• Cocoapods is already integrated, use whatever 3rd party library you want
• Simulator only, doesn't have to run run on a device.
• Use the latest XCode available on the App Store

Clone the repository and send us link to the project when you're done.
