如何在swift中訪問字典中包含的數組元素

Question

我花了一些時間嘗試搜索這個，但我還沒有找到解決方案。我正在嘗試訪問字典中的特定數組值。以下是我想要做的一般代碼/解釋。

var dict = ["1": [1,2,3,4,5], "2": [6,7,8,9,10], "3": [11,12,13,14,15]] 

//now lets say I want to access the 3rd value of dict["2"] = 8 
//I have tried the following and failed 

print(dict["2": [2]]) 
print(dict["2"][2]) 

感謝

Answer 1

這裏是你可以做到這一點的方式：

var dict = ["1": [1,2,3,4,5], "2": [6,7,8,9,10], "3": [11,12,13,14,15]] 
let temp = dict["2"]![2] // 8
