Nested and Associated Enum Values Swift - swift

Question

One of the best practices endorsed by NSHipster when dealing with tables or collection views is to use an enum to represent each section like so:
typedef NS_ENUM(NSInteger, SomeSectionType) {
SomeSectionTypeOne = 0,
SomeSectionTypeTwo = 1,
SomeSectionTypeThree = 2
}
That makes it really easy to do a switch statement or ifs like:
if(indexPath.section == SomeSectionTypeOne) {
//do something cool
}
For sections with static content, I extended the concept to include enums for each item:
typedef NS_ENUM(NSInteger, SectionOneItemType) {
ItemTypeOne = 0,
ItemTypeTwo = 1
}
if(indexPath.section == SomeSectionTypeOne) {
switch(indexPath.item) {
case SectionOneItemType:
//do something equally cool
default:
}
}
In Swift, I'd like to replicate the same behavior except this time taking advantage of nested enums. I've been able to come up with this so far:
enum PageNumber {
enum PageOne: Int {
case Help, About, Payment
}
enum PageTwo: Int {
case Age, Status, Job
}
enum PageThree: Int {
case Information
}
case One(PageOne)
case Two(PageTwo)
case Three(PageThree)
}
but I can't see how to go from an NSIndexPath and initialize the correct case and then use a switch statement to extract the values.

Don't think you can use nested enum to decide the section and row cell comes from. Because associated values and raw values can't coexist in Swift enumeration. Multiple enums are needed
enum sectionType: Int {
case sectionTypeOne = 0, sectionTypeTwo, sectionTypeThree
}
enum rowTypeInSectionOne: Int {
case rowTypeOne = 0, rowTypeTwo, rowTypeThree
}
//enum rowTypeInSectionTwo and so on
let indexPath = NSIndexPath(forRow: 0, inSection: 0)
switch (indexPath.section, indexPath.row) {
case (sectionType.sectionTypeOne.rawValue, rowTypeInSectionOne.rowTypeOne.rawValue):
print("good")
default:
print("default")
}
