iOS home task project

About this repository

This repository contains brand new iOS project with Storyboards removed and ready to write the UI programatically with UIKit so you don’t waste time to set it up. You can fork this repository and work on forked one and once you are ready you can create a pull request to this repository


  1. Create your own private github repository
  2. Push your solution to that repository
  3. Invite github user piotrdebosz when you are ready.


The main idea is to build an app that shows list of places where each place has its own set of photos.

Places screen

A place has name and thumbnail image and it’s up to you how to display it however they should be sorted in alphabetical order.

To retrieve the places you can use the following API:

When a place is tapped the app should go to the photos screen

Photos screen

Photos screen will have all photos of the place presented ordered by createdAt parameter showing the newest as the first one.

To retrieve the list of photos you can use the following API (replace [PLACE_ID] with the id you get from /places API call):

It is required to present photos in the UICollectionView in such a way that each cell contains single photo and the cell is filling all possible space (so showing one cell at the time). Think of it like a fullscreen photos gallery where user can see one photo at the time.

User should be able to switch between next / previous photo by swiping left and right

Additional requirements

  • There should be some kind of caching mechanism to download photo only if it’s not available in cache. There is no need for persistence so cache can reset every app launch. Cache should be limited to 10 last downloaded images. Please do not use NSCache.
  • UI should be written programmatically using UIKit therefore no using Storyboards / XIBs
  • The solution should not use Combine / RxSwift
  • You can use any 3rd party library you wish however in our current projects we try to keep the number of dependencies to minimum so it’d be good to justify it.
  • You can use any version of Swift / XCode / iOS

Thank you for your time and we are looking forward to see your solution
