How to scale a view up or down

Updated for Xcode 12.0

SwiftUI’s scaleEffect() modifier lets us increase or decrease the size of a view freely.

For example, we could make a text view five times its regular size like this:

Text("Up we go")
    .scaleEffect(5)

You can scale the X and Y dimensions independently if you want, allowing you to squash views like this:

Text("Up we go")
    .scaleEffect(x: 1, y: 5)

If you want more control, you can specify an anchor for your scaling like this:

Text("Up we go")
    .scaleEffect(2, anchor: .bottomTrailing)

That makes the text view twice its regular size, scaled from the bottom-right corner.
