<commit_before># Abstract classes and methods

* Proposal: [SE-0026](https://github.com/apple/swift-evolution/blob/master/proposals/0026-abstract-classes-and-methods.md)
* Author: <NAME>
* Status: **Deferred** ([Rationale](http://thread.gmane.org/gmane.comp.lang.swift.evolution/8809))
* Review manager: [<NAME>](https://github.com/jckarter/)

## Introduction

When developing framework and reusable code, we need to develop classes that are partially 
abstract with partial implementation. Protocol and protocol extensions provide this, but 
they cannot have attributes as classes have.
A partial class combines the behavior of a class with the requirement of implementing methods
in inherited class like protocols.
