How to loop over struct properties in Swift?

Question

Is it possible to iterate over properties of a struct in Swift?

I need to register cells-reuse identifiers in a view controller that makes use of many different cel

Answer 1

Now there's a much easier way to do this:

1: Create an Encodable protocol extension:

extension Encodable {
    var dictionary: [String: Any]? {
        guard let data = try? JSONEncoder().encode(self) else { return nil }
        return (try? JSONSerialization.jsonObject(with: data, options: .allowFragments)).flatMap { $0 as? [String: Any] }
    }
}

2: Make your struct/class conform to Encodable protocol

struct MyStruct: Encodable {...}
class MyClass: Encodable {...}

And then you can get a Dictionary representing your struct/class instance at any time:

var a: MyStruct
var b: MyClass

print(a.dictionary)
print(b.dictionary)

And then you can loop through the keys:

for (key, value) in a.dictionary { ... }
for (key, value) in b.dictionary { ... }
