The Playground in Xcode automatically updates as you type, but I can\'t figure out how to get the Playground to \"re-compile\".
In many cases this wouldn\'t matter,
Also, you can create your shortcuts.
Xcode > Preferences > Key Binding > (Search Execute Playground)
It is empty as a default, but you can assign anything.
Xcode 11 > Preferences > Key Binding > (Run Playground)
