I'm attempting to integrate postal code functionality into my Objective-C project by adding as submodule, but I'm encountering difficulties with importing it. Could you please verify the correct steps to do so? Is it feasible for a developer to incorporate postal code features into an Objective-C application? Other think I find is that the Result framework is missing in that. And when I try to add it through then it's also give error in **Result.framework** i.e. `Type of expression is ambiguous without a type annotation in class` **ResultProtocol** on line no 131 **return left.fanout(right)**
