Pattern: Use of class instead of AnyObject

Issue: -

Description

Prefer using AnyObject over class for class-only protocols.

Examples of correct code:

protocol SomeProtocol {}


protocol SomeClassOnlyProtocol: AnyObject {}


protocol SomeClassOnlyProtocol: AnyObject, SomeInheritedProtocol {}


@objc protocol SomeClassOnlyProtocol: AnyObject, SomeInheritedProtocol {}

Examples of incorrect code:

protocol SomeClassOnlyProtocol: ↓class {}


protocol SomeClassOnlyProtocol: ↓class, SomeInheritedProtocol {}


@objc protocol SomeClassOnlyProtocol: ↓class, SomeInheritedProtocol {}
