## What it is
The source code for many of The Omni Group's internal frameworks used to build their Mac, iOS, and watchOS applications, written primarily in Objective-C. It is intended to be added to Xcode workspaces and built with Xcode 13.1, targeting macOS 11, iOS 14, and watchOS 6.

## Use cases
- reuse Omni Group frameworks in my own Mac or iOS app
- build the TextEditor iPad example app from source
- learn how a mature Objective-C app framework stack is structured
- contribute fixes to Omni frameworks used in OmniFocus and other Omni apps
- set up xcconfig-based build configurations for Apple platforms

## When to choose
- you develop native Apple-platform apps in Objective-C and want battle-tested frameworks
- you want to study or reuse Omni's internal libraries in an Xcode project

## When to avoid
- you need a cross-platform or non-Apple framework
- you need a license-clear dependency — the repo has no license file
- you want Swift-first or actively updated libraries

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, developer-tools, sdk
- domain: developer-tools, apple-ecosystem, cross-platform
- platform: cpp
- tags: objective-c, frameworks, xcode, watchos, apple-platforms, omni-group, macos, ios, swift
