Hello! Thank you for taking time to review this code. The goal of the test is to show my coding and little bit design skills

• There are no pods or any third party services has been used or consumed, so just open PhotosApp.xcodeproj on Xcode
• Custom Dependency Injection has been used to use the proper testing
• MVVM-C was used in this project
• In unit test, mock network layer was used to get the data from json file but for app development normal network request has been consumed
• Unit test for DummyPhotoRepository was written to showcase
• Small and frequent commits approach is used while developing and designing the code and architecture

• ActivityIndicator can be added on DummyPhotosListViewController and DummyPhotoDetailViewController to show that data is fetching from server
• An Error Label or Toast can be added on DummyPhotosListViewController and DummyPhotoDetailViewController to show error to the user for better user experience
• UI wasn't focused on this task, improved UI can be implemented
• Network Request and Image caches can be implemented
• Multiple schemes and configuration can be created for production use
• .gitignore file can be added

This naming DummyPhoto is used because it may be conflicted in the idea of the team that we are using native Photo or might be a Photo object which can have image file

The server at the following url responds with JSON formatted data:

(GET) https://jsonplaceholder.typicode.com/photos

The response represents a list of photo objects:

[ {
}, {
"albumId": 1,
"id": 2,
"title": "reprehenderit est deserunt velit ipsam",
"url": "https://via.placeholder.com/600/771796", "thumbnailUrl": "https://via.placeholder.com/150/771796"
},
<...>
]

The following url returns a single entry for a given id:

https://jsonplaceholder.typicode.com/photos/{id}
