如何快速初始化数组

Question

I am completely new in swift and iOS developing. 我是Swift和iOS开发中的新手。 I want to initialize this array 我想初始化这个数组

I defined the array like this when my class starts 我上课时就这样定义了数组

 var i = 0
 var ArrayTitle = [NSString]()

and then I need to initialize it in one of the functions like this 然后我需要在这样的功能之一中对其进行初始化

 let ArrayTitl[i] = "text"

and I checked it even like this but the error is same 我什至这样检查它，但错误是相同的

let ArrayTitl[0] = "text"

but it has this Error Cannot assign to immutable expression of type '[Int]' 但它具有此错误Cannot assign to immutable expression of type '[Int]'

Appreciate any help. 感谢任何帮助。 thanks 谢谢

You are using a dynamic array so you need to append the value. 您正在使用动态数组，因此需要附加值。

Here's a small exemple: 这是一个小例子：

var arrayTitle = [String]()

arrayTitle.append("text")

print(arrayTitle[0]);
