contains(_:)
Test for membership of a particular UnicodeScalar in the CharacterSet.
func contains(_ member: UnicodeScalar) -> Bool Test for membership of a particular UnicodeScalar in the CharacterSet.
func contains(_ member: UnicodeScalar) -> Bool s10Foundation12CharacterSetV8containsySbs7UnicodeO6ScalarVF What are these?3TJDimport Foundationstruct CharacterSetA CharacterSet represents a set of Unicode-compliant characters. Foundation types use CharacterSet to group characters together for searching operations, so that they can find any of a particular set of characters during a search.
