Type AliasSwift5.9.0


    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 = _CustomPlaygroundQuickLookable

    The 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 { /*...*/ }
        // Otherwise, on Swift 4.0 and Swift 3.2 and earlier,
        // conform to CustomPlaygroundQuickLookable.
        extension MyType: CustomPlaygroundQuickLookable { /*...*/ }
