Swift Slowly: Day 13

Yesterday, I stopped so that I could spend time with my family. I’m going to pick up from the draw an arc spot.

Section 2: Draw Arc

Purpose: Learn about drawing in the application

The tutorial gives me a really good example for a computed property.

private var degreesPerSpeaker: Double {
    360.0 / Double(totalSpeakers)

Section 3: Draw the Ring

Purpose: Display the various segments for the speakers.

The following statement just looks wrong.

if speaker.isCompleted,
    let index = speakers.firstIndex(where: { $ == }) {

Are you really saving something by omitting the { and }?
