In Swift, you can use reflection to inspect types and their properties using the `Mirror` type. Reflection is particularly useful for debugging, logging, and dynamically accessing the properties of objects without knowing their exact structure at compile time.
Here's an example of how you can use `Mirror` to inspect a custom struct type and its properties:
struct Person {
var name: String
var age: Int
}
let person = Person(name: "John Doe", age: 30)
let mirror = Mirror(reflecting: person)
print("Type: \(mirror.subjectType)")
for child in mirror.children {
if let propertyName = child.label {
print("\(propertyName): \(child.value)")
}
}
