Small mobile coding challenge for prospective applicants

Mobile Developer Coding Challenge

This is a coding challenge for prospective mobile developer applicants applying through https://about.500px.com/jobs/

Goal:

Develop a simple app that allows viewing and interacting with a grid of currently popular 500px photos

• Fork this repo. Keep it public until we have been able to review it.
• Android: Java | iOS: Swift 3
• 500px API docs are here: https://github.com/500px/api-documentation. Please don't use deprecated iOS and Android SDKs.
• Grid of photos should preserve the aspect ratio of the photos it's displaying. Optionally: exclude nude images.
• Grid should work in both portrait and landscape orientations of the device.
• Grid should support pagination, i.e. you can scroll on grid of photos infinitely.
• When user taps on a photo on the grid she should show the photo in full screen with more information about the photo.
• When user swipes on a photo in full screen, preserve it's location on the grid, so when she dismisses the full screen, grid of photos should contain the last photo she saw.

Evaluation:

• Solution compiles. If there are necessary steps required to get it to compile, those should be covered in README.md.
• No crashes, bugs, compiler warnings
• App operates as intended
• Conforms to SOLID principles
• Code is easily understood and communicative
• Commit history is consistent, easy to follow and understand
