Common Mistakes

Using logical OR (||) instead of commas.

Using array brackets [] in case.

Using logical AND (&&) instead of commas.

In Swift switch cases, multiple values are separated by commas, not logical operators or array brackets.

switch letter {
    case [1]:

💡 Hint

Common Mistakes

Mixing vowels and consonants in the same case.

Using parentheses instead of commas.

Not enclosing characters in single quotes.

The first case matches vowels separated by commas; the second case matches consonants similarly.

Fill all three blanks to create a switch that prints "Small", "Medium", or "Large" for sizes 1-2, 3-4, and 5-6 respectively.

Swift

        print("Small")
    case [2]:
        print("Medium")
    case [3]:
