iOS Bootcamp Challenge

You must solve this challenge in order to be an attendee in the Wizeline
Academy’s iOS Bootcamp! But don’t worry, you won’t face any complex algorithms nor tricky questions about complexity. 🙂
Instead, you’ll have to solve a series of tasks regarding the basic principles of iOS Development.

What we have here is a little Pokedex app (which uses the famous PokeAPI).

The topics covered by the challenge are:

Networking & Data

The ListViewController contains a collection of PokeCell which display a list of Pokemons to the user.
You need to handle the PokeApi to retrieve each Pokemon detail.

// TODO: Implements generics to merge this methods into one
// TODO: Decode list of types & abilities


Requests in the project take different times to return data!
Make sure you are finished downloading all pokemons before updating the CollectionView

// TODO: Wait for all requests to finish before updating the collection view

Patterns and Architecture

To display more info about a Pokemon we provided a SearchBar and DetailViewController objects,
however, they are not in use yet! You need to implement them and handle the navigation
to allow the user to search and select a Pokemon from the ListViewController to display it in detail.

You can encapsulate your components in the same file or create more files in the project.

// TODO: Handle navigation to detail view controller

Views & Layouts

Let’s display the Pokemons details like the image, type, and attacks. Whatever you wanna display.
We provided a start UI using Layout Constraints in the code, but feel free to use Frames or the Storyboard!

// TODO: Display pokemon info (eg. types, abilities)


If you have time left address the extra TODO’s inside the project to show off your skills!

// TODO: Implement the SearchBar
// TODO: Use UserDefaults to pre-load the latest search at start
// TODO: Add a loading indicator when the app first launches and has no pokemons
