#Playground: Inline Playgrounds Without Leaving Your Source File

Aug 24, 2026 |

import Playgrounds unlocks the #Playground macro — drop it straight into a regular .swift file and Xcode runs it as a live playground canvas next to your code, no separate .playground bundle needed.

import Playgrounds

#Playground {
    let items = fetchItems()
    let total = items.reduce(0) { $0 + $1.price }
}

Open the file in Xcode and the canvas (⌥⌘Return) shows each statement’s result inline, same as classic Playgrounds, but scoped to that block and living right beside the production code it’s exercising — so it can call your app’s real types and functions directly, no copy-pasting into a standalone playground.

Takeaway: for quick “let me just try this” experiments against existing app code, reach for #Playground { } instead of spinning up a separate .playground file — it stays version-controlled with the code it tests and gets deleted in the same PR when you’re done.
