字符串＆GT; [字符串]和Array℃之间的差异; [英] Difference between [String] and Array<String>

问题描述

这是更好的方式来声明阵列和词典，我都用了：

Which is better way to declare Array and Dictionary, I have used both:

阵列＆LT;串GT;

[字符串]

对于我来说 [字符串] 是非常快的编码方面，而且在现实中如何都是在编译器和性能，我们应该遵循哪一个方面有什么不同？

For me [String] is very fast in terms of coding but in reality how both are different in terms of compiler and performance and which one we should follow?

A型雨燕阵列是用全为数组＆LT;元素>，其中
  元件是值的数组被允许存储的类型。您可以
  也写一个数组的简写形式为[元]的类型。
  虽然的两种形式是功能相同在简写形式
  为preferred 并指当使用本指南
  类型的数组中。

The type of a Swift array is written in full as Array< Element >, where Element is the type of values the array is allowed to store. You can also write the type of an array in shorthand form as [Element]. Although the two forms are functionally identical, the shorthand form is preferred and is used throughout this guide when referring to the type of an array.
