SWIFT Halloween Candy

Three nights with no sleep. Tried Classes, Structures and settled for normal functions... Now, if I don’t put the print line I don’t get an output... other combinations end up telling me that I can’t convert a String? to Int. I even tried to force the unwrap... I feel like I’m getting lost in something stupid. Help? ... ➡️ How do I tell the code to print the result? Thank youuu https://code.sololearn.com/cC60EIrRcy47/?ref=app Thank you 🙏🏻🙏🏻🙏🏻

I don't know if you code will solve the challenge. But searching for swift codes on code playground gives me this solution: print(calc(houses: houses)) Your problem is now that var houses is a String. I think you need to convert it to Integer.

let input = readLine() var num = Int(input!) print(num!) https://www.programiz.com/swift-programming/basic-input-output I am not familiar with swift so I don't know if this the only solution. Maybe it is better for to learn the basics of swift before you continue with this challenge.

thanks denise, that article is how i did all my tries. surely the point of SoloLearn would be to be able to develop enough skills to be able to solve easy puzzles like these? anyway ive amended the code and i can confirm that it still does not allow me as it tells me i need to convert num to integer on line 4 func calc(number: Int) -> Int { let input = readLine() var num = Int(input!) var solution = 2 / num * 100 return solution } let input = readLine() var num = Int(input!) print(calc(number: num!)) if i make that same num as non-optional ! i get a fatal error... its just weird!
