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?

Answer 1

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.
