Shape Factory

A small project based on Swift and leveraging Factory Design Patterns

Instructions:

• Open with Xcode
• Build and Run the App
• Click on a shape to select and display it's information
• Press "c" to create more shapes
• Pinch to zoom canvas
• Click and drag to pan canvas

Process description:

Due to the project specifications, I thought that it would have been a perfect example to leverage a factory design pattern for the shape objects' creation.

A ShapeFactory class has been created in order to support this. This class will create ShapeViews which will be configured for a corresponding Shape.

The ShapeView is in charge handling the representation of a Shape object and it's information.

The Shape object witholds all the properties of a shape such as position, size and color.

The ShapeView will then be added as a subview to the main canvas View.

A ViewController is used to control my main View and manage the creation of shape subviews through the ShapeFactory.å

Still to do:

• support Shape classes with proper getters and setters for all the properties
• support zoom on mouse wheel scroll
• add command to clear canvas
