Vaccine

What is Vaccine?

Vaccine is a framework that aims to make your apps immune to recompile-disease. Vaccine provides a straightforward way to make your application ready for code injection, also known as hot reloading. It provides extensions on application delegates, NSObject and view controllers.

Before you go any further, make sure that you have InjectionIII installed and have understood the core concept for code injection and its limitations.

Vaccine does not cut-out the need to ever recompile, but it opens up for faster iteration and seeing your application change instantly. There will be scenarios where you will have to recompile your application to see the changes appear. Worth noting is that code injection only works in the simulator and has no effect when running it on a device.
