split now complains about missing “isSeparator”

Question

After the latest upgrade of Swift 1.2, I can\'t figure out how to split a line of text into words. I used to do this:

let bits = split(value!, { $0 == \" \"}         


        

Answer 1

It seems that the order of the parameters changed in Swift 1.2:

let bits = split(value!, maxSplit: Int.max, allowEmptySlices: false,
                 isSeparator: { $0 == " "})

or, using the default values:

let bits = split(value!, isSeparator: { $0 == " "})

The predicate is now the last parameter and requires an external parameter name isSeparator because it is preceded by optional parameters.

The advantage of this change is that you can use the trailing closure syntax:

let bits = split(value!, maxSplit: Int.max, allowEmptySlices: false) { $0 == " " }

or

let bits = split(value!) { $0 == " " }
