WidgetKit

A place to experiment with WidgetKit. This readme has notes from official apple video about WidgetKit and glimpse of my applications.

WWDC 2020 : Widget Kit Notes

Meet WidgetKit

Widgets are NOT mini apps

Should project content from application than having tiny buttons!

Goals for a Great Widget Experience

• Glanceble
• Relevant
• Personalized

Widget kit is build entirely on SwiftUI - making it cross platform.

Color and Emoji Generation

A Color was made by using Random RGB Values as follows

// Keep in mind that it should be Double and NOT Int
let redValue = Double.random(in: 1...255)
let blueValue = Double.random(in: 1...255)
let greenValue = Double.random(in: 1...255)

// Making the Color
let baseColor =  Color(red:redValue/255,green:greenValue/255,blue:blueValue/255)

For the text I wanted a complementory Color, which was made using the RGB values of Base Color

// RBG Values of the baseColor
func complementColorGen(red: Double, green: Double, blue: Double) -> Color {
  // r' = max(r,b,g) + min(r,b,g) - r
  // b' = max(r,b,g) + min(r,b,g) - b
  // g' = max(r,b,g) + min(r,b,g) - g
  let axis : Double = max(red,blue,green) + min(red,blue,green)
  let redValue = axis - red
  let blueValue = axis - blue
  let greenValue = axis - green
  return Color(red:redValue/255,green:greenValue/255,blue:blueValue/255)
}

And, for producing a random Emoji - used the following code

func RandEmojGen() -> String {
  return String(UnicodeScalar(Array(0x1F300...0x1F3F0).randomElement()!)!)
}
