Declaration
var properties: Unicode.Scalar.Properties { get }Discussion
Use this property to access the Unicode properties of a Unicode scalar value. The following code tests whether a string contains any math symbols:
let question = "Which is larger, 3 * 3 * 3 or 10 + 10 + 10?"
let hasMathSymbols = question.unicodeScalars.contains(where: {
$0.properties.isMath
})
// hasMathSymbols == true
