}

To complete the challenge your code should match the below:

  1. You are creating a new array to hold the new output
  2. You are writing a for loop to handle this operation
  3. You are retiring the new array
func duplicate<T>(item:T, numberOfTimes:Int) -> Array<T> {
    var newArray: [T] = []
    for _ in 0..<numberOfTimes {
        newArray.append(item)
    }
    return newArray
}
