AI-generated Key Takeaways
-
The
Reviewstruct encapsulates information about a Google Places review, including its rating, text, author attribution, and publish date. -
It conforms to
CustomStringConvertible,Equatable, andHashableprotocols for easier manipulation and comparison. -
Reviewprovides properties for accessing the review's content in its original and localized forms, along with associated language codes. -
It includes a
relativePublishDateDescriptionfor displaying the review's age in a user-friendly format. -
Developers can instantiate a
Reviewwith detailed information about the review's attributes, such as publish date, rating, and author attribution.
Review
struct Reviewextension Review : Copyable, CustomStringConvertible, Equatable, Escapable, Hashable, Sendable-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
aandb,a == bimplies thata != bisfalse.Declaration
Swift
static func == (lhs: Review, rhs: Review) -> BoolParameters
lhsA value to compare.
rhsAnother value to compare.
-
The attribution that must be shown to the user if this review is displayed.
See Other Attribution Requirements for more details.
Declaration
Swift
var authorAttribution: AuthorAttribution? { get } -
A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the
String(describing:)initializer. This initializer works with any type, and uses the customdescriptionproperty for types that conform toCustomStringConvertible:struct Point: CustomStringConvertible { let x: Int, y: Int var description: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(describing: p) print(s) // Prints "(21, 30)"The conversion of
pto a string in the assignment tosuses thePointtype’sdescriptionproperty.Declaration
Swift
var description: String { get } -
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashableprotocol. The components used for hashing must be the same as the components compared in your type’s==operator implementation. Callhasher.combine(_:)with each of these components.Important
In your implementation of
hash(into:), don’t callfinalize()on thehasherinstance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.Declaration
Swift
func hash(into hasher: inout Hasher) -
The hash value.
Hash values are not guaranteed to be equal across different executions of your program. Do not save hash values to use during a future execution.
Important
hashValueis deprecated as aHashablerequirement. To conform toHashable, implement thehash(into:)requirement instead. The compiler provides an implementation forhashValuefor you.Declaration
Swift
var hashValue: Int { get } -
