書き方 

  • var 変数:[タイプ] = [タイプ]()
var 変数:[タイプ] = [タイプ](count:数, repeatedValue:値)
var 変数:[タイプ] = [値1,値2...]
↑

例 

  • var arr1:[Int] = [Int](count:3,repeatedValue:0)
var arr1:[Int] = [0,0,0]
↑

メモ 

  • let oddNumbers = [1, 3, 5, 7, 9, 11, 13, 15]
let streets = ["Albemarle", "Brandywine", "Chesapeake"]
// Shortened forms are preferred
var emptyDoubles: [Double] = []
// The full type name is also allowed
var emptyFloats: Array<Float> = Array()

var digitCounts = Array(repeating: 0, count: 10)

結合 

  • 変数 = 配列+配列
↑

メソッド

  • 値の追加配列.append(値)
    値の挿入配列.insert(値,atIndex:位置)
    配列.removeLast()
    配列.removeAtIndex?(番号)
    配列.removeRange(range)
    配列.removeAll()
    配列.count
