"Missing return in instance method expected to return 'Float'" Swift

I have this problem when I try to add print() in my override func. What should I do to avoid this?

I tried to add some return but nothing happens.

>Solution :

You need a return statement in the overridden function.

You can store the result of the call to super in a variable, do the print, then return the variable.

override func sum(_ first: Float, _ second: Float) -> Float {
    let result = super.sum(first, second)

    print("Message here")

    return result
}

Or you can print first and directly return the call to super:

override func sum(_ first: Float, _ second: Float) -> Float {
    print("Message here")

    return super.sum(first, second)
}
