v5.3.0

Enhancements

• Add Realm.objectWillChange, which is a Combine publisher that will emit a notification each time the Realm is refreshed or a write transaction is committed.

Fixed

• Fix the spelling of ObjectKeyIdentifiable. The old spelling is available and deprecated for compatibility.
• Rename RealmCollection.publisher to RealmCollection.collectionPublisher. The old name interacted with the publisher defined by Sequence in very confusing ways, so we need to use a different name. The publisher name is still available for compatibility. (#6516)
• Work around "xcodebuild timed out while trying to read SwiftPackageManagerExample.xcodeproj" errors when installing Realm via
  Carthage. (#6549).
• Fix a performance regression when using change notifications. (Since 5.0.0, #6629).

• File format: Generates Realms with format v10 (Reads and upgrades all previous formats)
