• We currently use Xcode 7.3.1 for iOS, watchOS, and Mac OS X. You'll probably have the best results if you do too.
• Add the projects you want to your workspace.
• Take a look in the Workspaces directory for a sample workspace for the TextEditor iPad example app.

• We require iOS 9.3 and Mac OS X 10.10.

We place our project-wide configuration options in xcconfig files, under OmniGroup/Configurations. The naming scheme of the files is fairly straightforward, hopefully. Each project has Omni-Global-{Debug,Release,...}.xcconfig as the basis for the corresponding configuration. Each Mac target has Omni-{Bundle,Application,Tool,...}-{Debug,Release,...}.xcconfig and each iOS target has Touch-{Application,Library}-{Debug,Release,...}.xcconfig. Each of these end point configurations when #includes 'superclass' configurations (with "Common" in the name).

The Workspaces directory contains a couple sample workspace that can be built from Xcode.

Enjoy!
