Sometimes you want to quickly generate an array in your swift code without having to manually type in the elements, you can quickly do that in Swift using the repeating method

Generate 20 Zeros Array

let twentyZeros = Array(repeating: 0, count: 20)
print(twentyZeros)

Output: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

Generate 50 Strings Array

let arrayOfString = Array(repeating: "City", count: 50)

This same method can be applied to any type in swift such as objects, just provide whatever you want to generate, and specify the count.
