lowercased
Returns a lowercased version of this character.
func lowercased() -> String Because case conversion can result in multiple characters, the result of lowercased() is a string.
let chars: [Character] = ["E", "É", "И", "Π", "1"]
for ch in chars {
print(ch, "-->", ch.lowercased())
}
// Prints:
// E --> e
// É --> é
// И --> и
// Π --> π
// 1 --> 1Other members in extension
