CustomPlaygroundQuickLookable
A type that explicitly supplies its own playground Quick Look.
This declaration was obsoleted in Swift 5.0: CustomPlaygroundQuickLookable will be removed in a future Swift version. For customizing how types are presented in playgrounds, use CustomPlaygroundDisplayConvertible instead.
typealias CustomPlaygroundQuickLookable = _CustomPlaygroundQuickLookableThe CustomPlaygroundQuickLookable 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.
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),
// conform to CustomPlaygroundDisplayConvertible.
extension MyType: CustomPlaygroundDisplayConvertible { /*...*/ }
#else
// Otherwise, on Swift 4.0 and Swift 3.2 and earlier,
// conform to CustomPlaygroundQuickLookable.
extension MyType: CustomPlaygroundQuickLookable { /*...*/ }
#endif
