Example demonstrating how to use versioning for Codable structs
// This gist demonstrates how you can implement versioning for a Codable struct to support loading
// old serialized data after changing the structure. Notable features of this solution:
//
// * No need to make new properties optional, or to perform post-processing on the struct after
// loading in ordeer to populate missing values
// * No need to change the call site - from the outside this struct behaves just the same
// as if we had implemented codable directly in the normal way.
// * Versioning can be applied individually to parents or leaves in a larger tree of
// structs without affecting the other elements
// * This approach will work even if the original struct was not designed with versioning in mind

guard let stringRange = Range<String.Index>(range, in: self) else {
fatalError("String index is out of range")
}
return self[stringRange]
