Visualizing Dependencies
In highly modularized code, you can have dozens of modules with a complex web of dependencies. These dependencies can be visualized using the GraphViz Dot Language.
To do so, in your terminal, navigate to the directory that contains your Package.swift file. Then run:
swift package show-dependencies --format dot > dependencies.dot
SPM will analyze the modules in your package and create a GraphViz dependency graph and store it in the dependencies.dot file. Then run:
dot -Tpng dependencies.dot -o dependencies.png
Now dot will create a visual graph of your dependencies in a .png file!
Tools available
There are many tools available to customize the look of your visual graph such as Graphviz Online. These can be very helpful for adding extra features to your graph such as color coding the types of your modules (test targets, macros, executables etc.).
