# PlaygroundQuickLook

The sum of types that can be used as a Quick Look representation.

## Declaration

```swift
typealias PlaygroundQuickLook
```

## Discussion

Discussion The PlaygroundQuickLook protocol is deprecated, and will be removed from the standard library in a future Swift release. To customize the logging of your type in a playground, conform to the CustomPlaygroundDisplayConvertible protocol, which does not use the PlaygroundQuickLook enum. If you need to provide a customized playground representation in Swift 4.0 or Swift 3.2 or earlier, use a conditional compilation block: #if swift(>=4.1) || (swift(>=3.3) && !swift(>=4.0))     // With Swift 4.1 and later (including Swift 3.3 and later), use     // the CustomPlaygroundDisplayConvertible protocol. #else     // With Swift 4.0 and Swift 3.2 and earlier, use PlaygroundQuickLook     // and the CustomPlaygroundQuickLookable protocol. #endif
