What is a property wrapper in Swift?

• A way to manage memory for properties

• A feature that automatically creates properties

• A mechanism to add additional behavior to a property without duplicating code

• A method for creating immutable properties

What does the @propertyWrapper keyword indicate?

• That the following variable is optional

• That the structure defines a property wrapper

• That the structure is a subclass of another type

• That the structure implements a protocol

In the Capitalized property wrapper, what is the purpose of the private var text property?

• To hold the current value of the property being wrapped

• To validate the input value of the property

• To store the capitalized version of the user input

• To format the string value for output

What does the wrappedValue property do in a property wrapper?

• It initializes the property wrapper

• It defines the behavior of the property when accessed or modified

• It checks the validity of the property’s value

• It overrides the property’s default initializer

How does the set method in the wrappedValue of the Capitalized wrapper transform the value?

• It converts the entire string to uppercase

• It applies the .capitalized method to the new value

• It replaces all spaces in the string with hyphens

• It ensures the string is always lowercase

What does the initializer init(wrappedValue:) in the Capitalized property wrapper do?

• It defines the behavior when the property wrapper is destroyed

• It validates the string value for correctness

• It sets the initial value of the wrapped property and applies the setter logic

• It ensures the getter logic is executed

In the User struct, what is the role of @Capitalized var name?

• It ensures the name property is immutable

• It transforms the name property into a capitalized string when set

• It validates the name property against a specific pattern

• It allows name to be stored directly without modification

What happens when this code is executed?

• The string "john doe" is stored and printed as-is

• The string "john doe" is stored in lowercase and printed in uppercase

• The string "john doe" is transformed to "John Doe" and printed

• The code throws an error because name is read-only

Which part of the property wrapper logic ensures the value of name is capitalized?

• The get method in wrappedValue

• The private var text property

• The set method in wrappedValue

• The initializer of the User struct
