Assembly Definitions in Unity are often introduced as a way to improve compile times—but their real value is architectural. In this video, we walk through how Unity compiles scripts by default, how to structure projects using asmdefs, and how to introduce assembly boundaries incrementally without rewriting your entire codebase. If your Unity project is starting to feel tangled, this video shows a concrete, realistic path to bringing structure back.
