Installation

The app should run as is. The deployment target is set to iOS 10.0. If you have any questions or issues, you can contact me at gbrickley88@gmail.com

Customization

• The Constants.h file holds values that we may want the ability to easily change. You can change the website that users are loaded from and also the number of users fetched at a time. If you change the STACK_EXCHANGE_SITE_NAME to an invalid website name, you can view the error handling I included.

Thoughts / Considerations

• As opposed to just loading one page, I added in some very basic pagination. Once you scroll to the bottom of the table view, the next page is loaded.
• Right now images are downloaded and save permanently in the Documents directory so that they are available for offline use. Depending on requirements and memory considerations, it may make sense to save them in a temporary directory so that they are available for offline use during the current app session, but then cleared from memory later on.
• I used a very simple setup to map the JSON API data to the CHLUser model, mainly in order to demonstrate my understanding of how objects are initialized and constructed. In a larger scale project it may be beneficial to use a JSON mapping library to speed up development.

Third-party libraries

I used three, installed using CocoaPods:

• AFNetworking - Although the newer iOS versions have much better built in networking tools, this is still my go-to for networking. A very well built and maintained framework with lots of built in additional features to make networking simple and reliable.
• MBProgressHUD - I've used this quite often on past projects. A nice way to quickly create nice looking progress indicators.
• DZNEmptyDataSet - Another favorite of mine, this UIScrollView/UITableView superclass provides delegate methods that allow you to customize your view in the case that your data set is empty.
