How about everyone. I'm trying to return an entity with an enum, not a tuple.
Currently I have already returned exceptions but my intention is to have entities by defects, because they are few.
I do this to return an exception with enum.
enum EXCEPTION: String, Error {
case REGISTER_TYPE = "You need register other type, example BANCA"
case LIST_ERROR = "You list index not exists"
}
I hope you can help me, regards.
Simply by having your enum implement the Error protocol, you can already use it to throw exceptions.
For example:
func someFunction() throws {
if someCondition {
throw EXCEPTION.REGISTER_TYPE
}
}
This function could then be used with a try catch block like this:
do {
try someFunc()
}
catch let error as EXCEPTION {
print(error) //REGISTER_TYPE
print(error.rawValue) //You need register other type, example BANCA
}
