Basics article available: StringsI absolutely love the many different category properties that were added to Swift’s Character type as part of Swift 5.0. I’ve been writing a ton of string parsing code lately, and these properties have been so incredibly useful.

character.isLetter // true
character.isNumber // false
character.isUppercase // true
character.isSymbol // false
character.isCurrencySymbol // false
character.isASCII // true
