Since Swift interoperates with Objective-C, we’ll be able to use Scripting Bridge to control OmniGraffle from Swift. Scripting Bridge allows developers to control AppleScript-enabled applications from languages other than AppleScript, including Python and Objective-C. To talk to OmniGraffle from Swift, we’ll use the Scripting Bridge framework, which was first introduced in Mac OS X 10.5 “Leopard”. Now switch to Xcode, navigate to File > New > Project and create a new OS X Command Line Tool written in Swift. A copy of the OmniGraffle document can be downloaded here. Rename the first canvas, Canvas 1, to Simple Graph and save the document. Note that it’s important to drag connections from the source node to the destination node as this determines the sources and destinations of line objects in OmniGraffle’s scripting interface merely changing the tail/head arrow type will not cut it. Next, add directed edges with the Line tool, as shown below. With the Shape tool, add four circles representing four different nodes and label them A-D. We’ll start with a clean slate and use the Auto-Resizing template (found under the Imperial Units category). Next, head over to the File menu and select New. ![]() Close any existing documents you may have open in OmniGraffle. We’ll start by creating a simple directed graph in OmniGraffle. We’ll then run the algorithm on a graph in the OmniGraffle canvas, coloring any strongly-connected components we find. In this article, we’ll implement Tarjan’s algorithm for finding the strongly-connected components of a directed graph (in Swift). One day I thought to myself, “wouldn’t it be cool if we could implement a graph algorithm in, say, Swift, and run it directly on the OmniGraffle canvas?” With OmniGraffle Pro’s extensive Scripting Dictionary and OS X’s Scripting Bridge framework, we can do just that. Stability - Fixed a crash when opening a SVG file.OmniGraffle by The Omni Group is a fantastic diagramming tool for OS X, and anyone studying graph theory is bound to find it useful for working through the details of graph algorithms.Stability - Fixed a crash undoing the merging of layers.Signing in to an Omni Account should now keep you signed in until you explicitly sign out, remove the app, or change your account password. Subscription Renewal - Fixed some issues which could cause the app to lose track of an active subscription, requiring a fresh Omni Account sign-in each time the subscription renewed.Multitasking - Worked around iPadOS 15 bug preventing the on-screen keyboard from appearing for all open documents.User Fonts - Restored support for custom fonts installed by the user.Omni Automation - Added support for triggering Omni Automation scripts and plug-ins from Shortcuts, using the new Omni Automation Script and Omni Automation Plug-In actions. ![]() OmniGraffle 3.17 introduces Omni Automation actions for Shortcuts, restores support for user installed fonts, and more. ![]()
