How to declare a Swift Array

Question

I'm trying to figure out my errors in a swift program it is my first program in swift and I'm learning the syntax. How would one declare an array in swift?

Answer 1

If you wish to declare an array in Swift there are two ways. The most popular and most idiomatic is to use square brackets around a type. For an Array of Ints you might have:

var myArrayOfInts : [Int]

This is syntax sugar for using the generic Array struct so you could equivalently write:

var myArrayOfInts : Array<Int>

Though I don't believe I have ever seen that written in any code (after the square bracket syntax was introduced) in any case that wasn't an example (just like this one) of how the two are equivalent.

Answer 2

你应该试试

 var temp = [Int]()

Answer 3

很简单

var myArray: [String] = []
