Swift Append to Array after indexpath.row

Question

I have a swift Array that I populate a UITableview with.

e.g

var array: Array<String> = ["ExampleString1","ExampleString2","ExampleString3"]

My question is how to do append all items that come after the Indexpath.row I press to a new array.

e.g I press the the first UITableview cell which is row 0 and in didSelectItemAtIndexPath I can pick up the indexpath

let test = array[indexPath.row]

If I pressed the first cell I want to add ExampleString2 and ExampleString3 by appending to my new array

var newArray: Array<String> = []
newArray.append(Everything After Indexpath that was pressed.)

Use a for loop, starting at indexPath.row+1 up to array.count-1 — Paulw11

var array = ["ExampleString1", "ExampleString2", "ExampleString3"]
let indexPath = 0 // Your indexPath

let newArray = array.enumerate().filter { $0.index > indexPath }.map { $0.element }

Something like this.

And using Paulw11's suggestion: (if he posts his answer I'll delete mine)

var newArray: [String] = []

for index in indexPath + 1...array.count - 1 {
    newArray += [array[index]]
}

Another variation based on Paulw11's suggestion:

let newArray = array[indexPath + 1...array.count - 1].map { $0 }

Or:

let newArray = Array(array[indexPath + 1...array.count - 1])

They all print out:

print(newArray) // ["ExampleString2", "ExampleString3"]

You'll have to add some safety checks because the way it is right now will cause an error if your indexPath.row is the last element. In that case, my original answer (the first one) is more safe.
