Swift 配列のメモ

宣言の書き方

let emojis = ["🍽","🍎","🍧","🍻","🏋️‍♀️","👔","💇🏻‍♂️","🧻","🏝","🏡","🌟","🚰","🚌","🚗","📱","📚","🏥","🏪"]
var days:[String] = []
var moneys:[Int16:String] = [:]
var arrayFloats: Array<Float> = Array()

指定要素分を固定値で初期化
Array(repeating: 初期値, count: 要素数)

var myArray = Array(repeating: 0, count: 3)

結果：
[0,0,0]

配列要素の追加

        emojis.append("m")
        emojis += ["m"]

配列を結合する

let s: String = emojis.joined()
let s: String = emojis.joined(separator: "-")

Sort

let s = emojis.sorted()
emojis.sort()
//複雑な配列の場合
struct Person {
    var name: String
    var sex:Bool
}

var users = [...]

users.sort {$0.name < $1.name}
