realm/realm-swift v10.52.0

on GitHub

Enhancements

• Add @ObservedSectionedResults.remove(atOffsets:section:) which adds the ability to
  remove a Realm Object when using onDelete on ForEach in a SwiftUI List.
• Add support for Xcode 16 beta 1 and fix some of the new warnings. Note that
  this does not yet include full support for Swift 6 language mode
  (#8618).
• Realm.asyncWrite() and Realm.asyncRefresh() now use the new #isolation
  feature to avoid sendability warnings when building with Xcode 16
  (#8618).
• Include the originating client reset error message in errors reporting that
  automatic client reset handling failed. (Core #7761)
• Improve the performance of insertion-heavy write transactions, particularly
  when setting a large number of properties on each object created
  (Core #7734).
• App now trims trailing slashes from the base url rather than producing
  confusing 404 errors. (Core #7791).

Fixed

• Deleting a Realm Object used in a @ObservedSectionedResults collection in SwiftUI
  would cause a crash during the diff on the View. (#8294, since v10.29.0)
• Fix some client resets (such as migrating to flexible sync) potentially
  failing if a new client reset condition (such as rolling back a flexible sync
  migration) occurred before the first one completed.
  (Core #7542, since v10.40.0)
• The encryption code no longer behaves differently depending on the system
  page size, which should entirely eliminate a recurring source of bugs related
  to copying encrypted Realm files between platforms with different page sizes.
  One known outstanding bug was (RNET-1141),
  where opening files on a system with a larger page size than the writing
  system would attempt to read sections of the file which had never been
  written to (Core #7698).
• There were several complicated scenarios which could result in stale reads
  from encrypted files in multiprocess scenarios. These were very difficult to
  hit and would typically lead to a crash, either due to an assertion failure
  or DecryptionFailure being thrown (Core #7698, since v10.38.0).
• Encrypted files have some benign data races where we can memcpy a block of
  memory while another thread is writing to a limited range of it. It is
  logically impossible to ever read from that range when this happens, but
  Thread Sanitizer quite reasonably complains about this. We now perform a
  slower operations when running with TSan which avoids this benign race
  (Core #7698).
• Realm.asyncOpen() on a flexible sync Realm would sometimes fail to wait for
  pending subscriptions to complete, resulting in it not actually waiting for
  all data to be downloaded. (Core #7720,
  since flexible sync was introduced).
• List<AnyRealmValue>.clear() would hit an assertion failure when used on a
  file originally created by a version of Realm older than v10.49.0.
  (Core #7771, since 10.49.0)
