iOS Functions in Swift Adding Power to Functions Function Parameters

Cannot assign the value returned by a function to a new constant.

Hi, this is the code I wrote:

---Swift

func getRemainder(value a: Int, divisor b: Int) -> Int {

return(a % b)

}

let result = getRemainder(10, 3)

---Swift

What am I doing wrong?

Thank you

functions.swift
// Enter your code below

func getRemainder(value a: Int, divisor b: Int) -> Int {

    return(a % b)
}

 let result = getRemainder(10, 3)

Hi there, Tatiana! Oh wow you are soooo close to having this correct! You set up value and divisor as your external labels. This means that you have to use them when calling the function, otherwise you'll get a compiler error. Take a look at how close you really are:

 let result = getRemainder(value: 10,  divisor: 3)

Hope this helps! :sparkles:

Thank you Jennifer!

When you are stuck on challenges it can often be helpful to press the preview button and look at the error message being produced, the errors can often be more helpful than you might expect.

swift_lint.swift:13:27: error: missing argument labels 'value:divisor:' in call
 let result = getRemainder(10, 3)
                          ^
                           value:  divisor: 

The error comes from the fact that you did not assign labels to the arguments when you called your method, adding the labels that you specified when you created the method like this:

let result = getRemainder(value: 10, divisor: 3)

Will allow your code to pass the challenge.

Thank you Andren!
