Implements a simple piano

Swift Piano Task

This project solves the problem given at this Github account. For completness I left the original text and task description.

Original Task Description

Build a small piano like application in Swift with white and black keys, playing a sound on pressing the keys.

IMPORTANT: Don't use Storyboards but purely code to create the views. A starting point for such as structure is given in the SwiftPianoTemplate XCode project.

Minimum requirements

• View code manually written with UIKit's UIViews (no Storyboards)
• Touchable black and white keys
• Different sounds played for black and white keys

Optional features

• Layouting with black keys "overlapping" the white keys as in a real piano
• Visual feedback on touching the keys
• Correct piano tone scales on "playing" the keys

SwiftPianoTemplate

This project contains a sample starter code for a project programmatically creating UIViews instead of Storyboards. Feel free to use this starter code for your task.

Piano Sounds

The directory grand-piano-mp3-sounds contains sample sounds you can use for this task. Alternatively you can use sounds from https://github.com/pffy/mp3-piano-sound or other sample sounds of your preference.
