Parser and DOM over the xcode pbxproj
npm install pbxproj-domParser and DOM over the xcode pbxproj

Sample usage:
``
import { Xcode } from "pbxproj-dom/xcode";
const xcode = Xcode.open(pbxprojPath);
xcode.setManualSigningStyle("MyAppTarget");
xcode.save();
`
The ultimate goal would be one day the module to support a JavaScript API for Xcode modifications similar to the Cocoapods ruby:
```
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['SWIFT_VERSION'] = '3.0'
end
end
end
