7Segment

Emulating a 7-Segment display in Swift.

This project was created to practise the following:

• Complex Auto-Layout constraints such as ensuring all segment in the 7-segment display align and re-size correctly.
• Bit manipulation and bitwise operations in Swift.
• Implementing 7-segment logic without using cascading if-else.

Setup

• Include the contents of the 7Segment Classes(All classes with SG prefix) group in Xcode into the project.
• Add an instance of SGSevenSegmentViewController to your ViewController as a childViewController.
• Call display(value: x) where x is an Int between 0-15. Illegal values simply display a '-'.
