In Swift, the Mirror API enables reflection, making it possible to inspect the properties, types, and values of instances at runtime. Unlike reflection in other languages that allow for modification of objects at runtime, Swift's reflection capabilities are designed around examining rather than modifying. This aligns with Swift's principles of type safety and performance.
When using the Mirror API, it’s important to consider the performance implications of using it, as it requires more computing resources than direct access methods and is not recommended for performance-critical parts of an application.
In this chapter we showed how we could use the Mirror API to inspect the properties of a structure and class, revealing details such as property names and values, and even the instance's display style and underlying type category.
Advanced use cases for the Mirror API include debugging complex data structures, custom serialization and dynamically exploring...
