class Assignment {

  func fibonacci(n: Int) {

    // Write your code here 👇
    var n1 = 0
    var n2 = 1
    
    if n == 0 {
      print("Invalid")
    } else if n == 1 {
      print(n1)
    } else if n == 2 {
      print(n1, n2)
    } else {
      var array = [n1, n2]
      for _ in 2..<n {
        let n3 = n1 + n2
        n1 = n2
        n2 = n3
        array.append(n3)
      }
      print(array)
    }

  }
}

// Test your function here for different values of n 👇
let test = Assignment()
test.fibonacci(n: 11)

This is my solution

func fibonacci(n: Int) {

    var array: [Int] = []
    for i in 0..<n {
        if i == 0 || i == 1 {
            array.append(i)
        } else {
            array.append(array[i-2] + array[i-1])
        }
    }
    print(array)
}

class Assignment {
var numbers = [0, 1]
var i: Int = 0
var number: Int = 0

func fibonacci(n: Int) {
    while (i < (n-2)) {
        number = numbers[i] + numbers[i + 1]
        numbers.append(number)
        i += 1
    }
print(numbers)
}

}

class Assignment {
    func fibonacci(n: Int) -> Void {
        var sequence = [0, 1]
        for _ in 2..<n {
            sequence.append(sequence[sequence.count - 1] + sequence[sequence.count - 2])
        }
        print(Array(sequence.prefix(n)))
    }
}
