Suggested change

	func dictionaryToJsonData(_ dictionary: [String: Any]) -> Data? {
	return try? JSONSerialization.data(withJSONObject: dictionary, options: [])
	}
	func dictionaryToJsonData(_ dictionary: [String: Any]) -> Data {
	return try JSONSerialization.data(withJSONObject: dictionary, options: [])
	}

This should not return an optional:
func convertUserDataType(dictionary: [String: Any]) throws -> UserInfo

[metalurgical]

This do {} catch {} can be removed.

i.e

            let decoder = JSONDecoder()
            let userInfo = try decoder.decode(UserInfo.self, from: jsonData)
            return userInfo

[metalurgical]

Needs to be of the form:

throw SomeError.SomeCase("Invalid UserInfo Data structure")

Even better is it doesn't accept a message, then it fits nicely in the error handling:

 throw UserInfoError.InvalidData

[metalurgical]

The do {} catch {} can be removed here.

Many of the structs declared here will be in the next version of customauth.

I'd suggest we wait with this PR for that and then update the dependency instead and use it from there.
