Eject

Eject is a utility to transition from Interface Builder to programatic view layout. This is done by using code generation to create a .swift file to replace the view hierarchy managed by the .xib file.

Why?

One common pain point with Interface Builder is that as a view becomes more dynamic and is managed more programatically, Interface Builder becomes less helpful. This tool lets developers use Interface Builder without that concern, giving them an Eject button to hit when Interace Builder starts getting in the way, and provides an easy path to transition to full programatic view layout.

But But

Yes, I understand that this is probably a bad idea. But it might not be.

Usage

Install with homebrew:

brew install eject

Use on the command line:

eject --file /path/to/MassiveViewController.xib

Copy and paste code into .swift file, and remove the .xib:

rm /path/to/MassiveViewController.xib

Or to see what changed in a xib file by looking at the changes in generated code:

TMP=`mktemp` && git show HEAD:$XIB > $TMP && diff <(eject --file $XIB ) <(eject --file $TMP)

eject will generate code for everything it can in the .xib file. If there is any XML that eject does not understand, it will print out a warning message. Open an Issue with any warnings, bugs or ideas you may have.

Features

Does it work?

The Unit Tests show how much work is done. UIKit coverage is configured by the CocoaTouchBuilder using various Builders. Some configuration is generated from Interface Builder .inspector files.

This should still be considered an Alpha quality tool.
