This should work:
func duplicate<T>(item: T, numberOfTimes: Int) -> [T] {
var array: [T] = []
for _ in 1...numberOfTimes {
array.append(item)
}
return array
}

var someArray = [item]
for _ in 1..<numberOfTimes {
someArray.append(item)
}
return someArray as! [T]
}
duplicate(item: 2, numberOfTimes: 3)
this worked
