github realm/realm-cocoa v5.3.4


  • Accessing a Realm after calling deleteAll() would sometimes throw an exception with the reason 'ConstIterator copy failed'. (#6597, since 5.0.0).
  • Fix an assertion failure inside the migrate_links() function when upgrading a pre-5.0 Realm file.
  • Fix a bug in memory mapping management. This bug could result in multiple different asserts as well as segfaults. In many cases stack backtraces would include members of the EncyptedFileMapping near the top - even if encryption was not used at all. In other cases asserts or crashes would be in methods reading an array header or array element. In all cases the application would terminate immediately. (Core #3838, since v5.0.0).
