iOS Crypto WebSocket Client

A work-in-progress sample iOS app using WebSockets to provide live prices for cryptocurrencies in a list and detailed view.

To do list

• Create list view with test data
• Hook up to WebSocket API
• Use the data from the WebSocket API to populate the list
• Format for the correct tick size ($250.5 -> $250.50), requires tick size from the API because there are cryptocurrencies with a tick size > 2
• Create detailed view with test data
• Loading list on first time behaviour
• Reloading list behaviour (swipe down to reload, loading indicator)
• Handle error from the network
• List search (Swipe down to reveal search, like in the iOS settings app)
• Filtering and sorting
• Last updated timestamp
• Use the WebSocket server over wss (WebSocket Secure) and remove the exception for non-secure on localhost in Info.plist
