Editors created in Processing are capable of running several different computer languages; basically if there is a compiler for a language, a Processing editor app can run the source code for that language. The following is a MacOS only demonstration of this. It uses swiftc from the command line to compile .swift source code for an iOS app and then runs the code on a simulator provided by XCode (installation required). It also requires two .jar files: one for Info.plist creation and one for editor syntax highlighting. Details and source code are here: https://github.com/vsquared/iOSEditor_Processing

Addendum:
Will also run SwiftUI code in addition to UIKit:
import SwiftUI
struct ContentView: View {
var body: some View {
Circle()
.fill(.blue)
.padding()
.overlay(
Image(systemName: "figure.basketball")
.font(.system(size: 144))
.foregroundColor(.white)
)
}
}
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
MyApp.main()
Output:
