Eureka Get Dictionary Values Swift

Question

I am using the Eureka form library found here . I am trying to iterate over the dictionary values of the form and only print the values that are true; not nil or not false. So far I have

     let valuesDictionary = form.values()

        for (_, version) in valuesDictionary
        {

            if version != nil || version as! Bool != false // error here

            {
                print (version!)
            }

        }

I am getting the following error on the if statement:

fatal error: unexpectedly found nil while unwrapping an Optional value

Answer 1

Do it like this:

for (_, version) in valuesDictionary
{
    if let version = version, version as? Bool != false {
        print(version)
    } 
}

This will translated as:

• if let version = version : if there is a value ( version is not nil )

After checking if it's not null ( optional binding ), as a where condition:

• version as? Bool != false version as? Bool != false : checks tow points:

1- is version could be cast to Bool .

2- If the first point is true, check if version is not false .
