#Mobile App Developer Coding Challenge

Goal:

Develop a currency conversion app that allows a user to convert an input value by any of the supplied rates.

• Fork this repo. Keep it public until we have been able to review it.
• Android: Java/Kotlin | iOS: Swift
• exchange rates must be fetched from: http://fixer.io/
• rates should be persisted locally and refreshed no more frequently than every 30 minutes
• user must be able to select the input currency from the list of supplied values

Evaluation:

• App operates as asked
• No crashes or bugs
• SOLID principles
• Code is understandable and maintainable

UI Suggestion: Input field with a drop-down currency selector, and a list/grid of converted values below.
