In iOS (Swift/Objective-C), to determine the data category of a class, you can use:

• In Swift, the is operator to check for membership in a type or protocol.
• The type(of:) method to get the type of an object.
• In Objective-C, the function class_isMetaClass or the methods isKindOfClass: and isMemberOfClass:.

Example in Swift:

class Animal {}
class Dog: Animal {}

let dog = Dog()

if dog is Animal {
    print("dog belongs to the category Animal")
}

print(type(of: dog)) // Will print "Dog"

This way, you can determine which class or category an object belongs to.
