swift - Difference between [String] and Array<String>

Question

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

Array<String>

[String]

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?

From iOS Developer Library on Swift...

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.
