We'll start with a figure that shows how our finished clock view will look:

The outer, thinner arc will display minutes and the inner arc will display hours, so the preceding figure is showing the time to be 08:22.

Note

I guess this is a clock for those who don't need to be too fussy about the exact time.

In this view, we will not use Core Graphics code directly; rather, we will use AppKit's wrapper functions, which simplify much of the drawing code to a set of standard calls with standard default values.

Note

Don't worry; in the next section we'll be getting our hands dirty with direct Core Graphics manipulation.

Creating a custom view with AppKit

The first thing we need to do is create a class and make the custom view an instance of that:

1. Create a new Cocoa class file, name it DialClockView, and make it a subclass of NSView.
2. This will give you a stub implementation of the DialClockView class in a file named DialClockView.swift.
3. In Interface Builder...
