github realm/realm-cocoa v5.3.2


  • Fix a file format upgrade bug when opening older Realm files.. Could cause assertions like "Assertion failed: ref != 0" during opening of a Realm. (Core #6644, since 5.2.0)
  • A use-after-free would occur if a Realm was compacted, opened on multiple threads prior to the first write, then written to while reads were happening on other threads. This could result in a variety of crashes, often inside realm::util::EncryptedFileMapping::read_barrier. (Since v5.0.0, #6626, #6628, #6652, #6655, #6656).


  • File format: Generates Realms with format v10 (Reads and upgrades all previous formats)
  • Realm Object Server: 3.21.0 or later.
  • Realm Studio: 3.11 or later.
  • APIs are backwards compatible with all previous releases in the 5.x.y series.
