Splits the text by a separator. If the separator is set to Custom you can add a customSeparator to split by any character you want.
splitText(text: <#Array or String#>, separator: <#Type (WFTextSeparator)#>, customSeparator: <#String (Allows Variables)#>)
splitText(text: "["Hello-World", "Jello-World"]", separator: Custom, customSeparator: "-")
