ExpressibleByUnicodeScalarLiteral
A type that can be initialized with a string literal containing a single Unicode scalar value.
protocol ExpressibleByUnicodeScalarLiteralThe String, StaticString, Character, and Unicode.Scalar types all conform to the ExpressibleByUnicodeScalarLiteral protocol. You can initialize a variable of any of these types using a string literal that holds a single Unicode scalar.
let ñ: Unicode.Scalar = "ñ"
print(ñ)
// Prints "ñ"Conforming to ExpressibleByUnicodeScalarLiteral
To add ExpressibleByUnicodeScalarLiteral conformance to your custom type, implement the required initializer.
Requirements
associatedtype UnicodeScalarLiteralType : _ExpressibleByBuiltinUnicodeScalarLiteralA type that represents a Unicode scalar literal.
init(unicodeScalarLiteral: Self.UnicodeScalarLiteralType) Creates an instance initialized to the given value.
