Accessing a String Enum by index

Question

I have an enum in C and the index needs to be represented by a String.

How can a Swift enum of String type be used by integer index?

I would like to copy the enum to Swift, set the type to string and define all of the raw values to display text, and then use the C enum value to extract the raw value text for the Swift String enum.

Otherwise I will just create an array of strings.. But the enum would be more usable.

Answer 1

Swift 4.2 introduced CaseIterable which does exactly the same thing without the need to declare an allValues array. It works like this:

enum MyEnum: String, CaseIterable {     case foo = "fooString"     case bar = "barString"     case baz = "bazString" } 

and you can access it's values by

MyEnum.allCases 

or a value at a specific index by

MyEnum.allCases[index]
