This is a category. Given that it’s call “SomeDelegate”, I suspect that someone was just breaking up the code in their implementation file to group all the delegate methods together. Some people use multiple
@implementationblocks to do that. This is the original use of categories. More often today, categories are used to extend existing classes. See the above link for more information.
