Random String containing of Block elements (an alternative to Lorem Ipsum?)

blocks.swift

extension String {
    private static let blockElements = (9600...9631)
        .compactMap { Unicode.Scalar($0) }
        .map { Character($0) }
    
    static func blocks(_ length: Int = 8) -> String {
        let choices =  (1...length)
            .map { _ in String.blockElements.randomElement()! }
        
        return String(choices)
    }
}
