Declaration

protocol ExpressibleByBooleanLiteral

Overview

Bool, DarwinBoolean, ObjCBool, and WindowsBool are treated as Boolean values. Expanding this set to include types that represent more than simple Boolean values is discouraged.

To add ExpressibleByBooleanLiteral conformance to your custom type, implement the init(booleanLiteral:) initializer that creates an instance of your type with the given Boolean value.
