Realm v0.87.0 Release Notes

Release Date: 2014-10-21 // over 9 years ago

  • API breaking changes

    • RLMArray has been split into two classes, RLMArray and RLMResults. RLMArray is used for object properties as in previous releases. Moving forward all methods used to enumerate, query, and sort objects return an instance of a new class RLMResults. This change was made to support diverging apis and the future addition of change notifications for queries.
    • The api for migrations has changed. You now call setSchemaVersion:withMigrationBlock: to register a global migration block and associated version. This block is applied to Realms as needed when opened for Realms at a previous version. The block can be applied manually if desired by calling migrateRealmAtPath:.
    • arraySortedByProperty:ascending: was renamed to sortedResultsUsingProperty:ascending
    • addObjectsFromArray: on both RLMRealm and RLMArray has been renamed to addObjects: and now accepts any container class which implements NSFastEnumeration
    • 🏗 Building with Swift support now requires Xcode 6.1

    ✨ Enhancements

    • ➕ Add support for sorting RLMArrays by multiple columns with sortedResultsUsingDescriptors:
    • ➕ Added method deleteAllObjects on RLMRealm to clear a Realm.
    • ➕ Added method createObject:withObject: on RLMMigration which allows object creation during migrations.
    • ➕ Added method deleteObject: on RLMMigration which allows object deletion during migrations.
    • ⚡️ Updating to core library version 0.85.0.
    • Implement objectsWhere: and objectsWithPredicate: for array properties.
    • ➕ Add cancelWriteTransaction to revert all changes made in a write transaction and end the transaction.
    • 👉 Make creating RLMRealm instances on background threads when an instance exists on another thread take a fifth of the time.
    • 👌 Support for partial updates when calling createOrUpdateWithObject: and addOrUpdateObject:
    • 👍 Re-enable Swift support on OS X
