realm/realm-swift v5.5.1

on GitHub

Fixed

• During integration of a large amount of data from the server, you may get "Assertion failed: !fields.has_missing_parent_update()" (Core #4497, since v5.0.0)
• Queries of the form "a.b.c == nil" would match objects where b is nil if c did not have an index and did not if c was indexed. Both will now match to align with NSPredicate's behavior. ([Core #4460]realm/realm-core#4460), since 4.3.0).
• Restore support for upgrading files from file format 5 (Realm Cocoa 1.x). (Core #7089, since v5.0.0)
• On 32bit devices you may get exception with "No such object" when upgrading to v10.* (Java #7314, since v5.0.0)
• Fix "Invalid ref translation entry [16045690984833335023, 78187493520]" assertion failure which could occur when using sync or multiple processes writing to a single Realm file. (#7086, since v5.0.0).
• Restore support for upgrading files from file format 5 (Realm Cocoa 1.x). (Core #7089, since v5.0.0)
• Fixed an issue where creating an object after file format upgrade may fail with assertion "Assertion failed: lo() <= std::numeric_limits<uint32_t>::max()" (#4295, since v5.0.0)
• Fast-enumerating a List after deleting the parent object would crash with an assertion failure rather than a more appropriate exception. (Core #4114, since v5.0.0).
• Fix a race condition which could potentially allow queries on frozen Realms to access an uninitialized structure for search indexes (since v5.0.0).
• Fix crash in case insensitive query on indexed string columns when nothing matches (#6836, since v5.0.0).
• Null values in a List<Float?> or List<Double?> were incorrectly treated as non-null in some places. It is unknown if this caused any functional problems when using the public API. (Core PR #3987, since v5.0.0).
• Limit availability of ObjectKeyIdentifiable to platforms which support Combine to match the change made in the Xcode 12.5 SDK. (#7083)
