why do i get fatal error because of Index out of range?

var numbers = [45, 73, 195, 53]

//Write your code here
 //Replace this comment with your code.
var computedNumbers : [Double] = Array() 
for i in 0...numbers.count-1 {computedNumbers[i] = Double(numbers[i])*Double(numbers[i])}
print(computedNumbers)

When I try to run the code on swift code it gives me the following error: Fatal error: Index out of range. I'm trying to reproduce an array of double by multiplying every element in numbers array by itself.

your computedNumbers array is empty and you are trying to access computedNumbers[i] value in your for loop which is empty. if you want to add data in it, try this instead: 

var numbers = [45, 73, 195, 53]

//Write your code here
 //Replace this comment with your code.
var computedNumbers : [Double] = []
for i in 0...numbers.count-1 {
  let num = Double(numbers[i])*Double(numbers[i])
  computedNumbers.append(num)
} 
print(computedNumbers)
