Squircle in SwiftUI

squircle.swift

// Run in Swift Playground

import SwiftUI
import PlaygroundSupport

struct ContentView: View {
    var body: some View {
        Rectangle()
            .fill(Color.red)
            .frame(width: 200, height: 200)
            .clipShape(RoundedRectangle(cornerRadius: 50, style: .continuous))
    }
}

PlaygroundPage.current.setLiveView(ContentView())

Thanks a ton for this!

You are on top of Google search. Congratulations and thanks!

BTW, now (from iOS 17) you don't need to explicitly set .continuous style, as it's already set by default.
