What is com.apple.InterfaceBuilder.IBCocoaTouchPlugin

Question

I wanted to know what does it mean, and why it is used in code:

com.apple.InterfaceBuilder.IBCocoaTouchPlugin

I have one source code where:

<plugin identifier = "com.apple.InterfaceBuilder.IBCocoaTouchPlugin" version = "3746" />

has been used. Why do we use it?

Answer 1

That plugin identifier tells Xcode that any Interface Builder Document (Storyboard or XIB) was built with Xcode, and the specific version of Xcode/Interface Builder that the interface was created with.
