# Question about Arrays from text Field

How can I get from the text taped in text Field an Array of type: [String], or even better-[Int64] or [Int]?

You mean put the value of a text field into an array?

No. I mean to get an array from the Symbols typed into a text field. For example: If in a text field typed this- “20 30 40 50 60” I need to get an Array [20, 30, 40, 50, 60]

In order to do that you will have to get the string that the user typed in and then convert it into an array.

Here is an example from Playground

``````let char = "10 20 30 40 50 60 70 80 90"
let stringArray: [String] = char.components(separatedBy: " ")
let integerArray = stringArray.map { Int(\$0)!}
print(integerArray)
``````

The result is:

``````[10, 20, 30, 40, 50, 60, 70, 80, 90]

``````

It would be better to use `compactMap` to convert the values from `String` to `Int` in case the user typed in something that can’t be cast to an `Int`. That would result in a `nil` value, which means you would need an array of Optional `Int`. Or use `compactMap` to filter out all the `nil` values. And then you don’t need to force unwrap the casting result.

So, like this:

``let integerArray = stringArray.compactMap { Int(\$0) }``

Good suggestion Patrick.

This works nicely when you mix up the numbers and have the result sorted too.

``````let char = "20 10 40 60 50 70 80 30 90 A ^ <"
let stringArray: [String] = char.components(separatedBy: " ")
let integerArray = stringArray.compactMap { Int(\$0) }.sorted()
print(integerArray)
``````

Output:

``````[10, 20, 30, 40, 50, 60, 70, 80, 90]
``````
