[Swift]多次元配列の宣言の仕方

Posted at 2014-11-01

#多次元配列の宣言の仕方

誤った宣言

let matrix:String[][] = [["hoge","fuga"] ,["ohayo","hello"]]

「Array types are now written with the brackets around the element type」というエラーが出ます。

正しい宣言

let matrix:[[String]] = [["hoge","fuga"] ,["ohayo","hello"]]

println(matrix[0][1])//"fuga"

二重括弧の中に型名を入れると動くようです。
