Cannot iterate over Enumeration

Question

Here is an example from book Programming in Scala

object Color extends Enumeration {
    //val Red, Green, Blue = Value
    val Red = Value("Red")
    val Green = Value("Green")
}

for (d <- Color) print(d + " ") //Error value foreach is not a member of
                                // object xxx.Color

I have latest version of Scala. Is it the reason for error?

Answer 1

This should be:

for (d <- Color.values) print(d + " ")

There used to be a foreach method in Enumeration, which is why doing just for (d <- Color) worked. But it has been deprecated, and then removed.
