v10.50.1

Enhancements

• Update release packaging for Xcode 15.4.

Fixed

• @AutoOpen and @AsyncOpen failed to use the initialSubscriptions set in
  the configuration passed to them (PR #8572, since v10.50.0).
• App.baseURL was always nil (PR #8573, since it was introduced in v10.50.0).

Compatibility

• Realm Studio: 15.0.0 or later.
• APIs are backwards compatible with all previous releases in the 10.x.y series.
• Carthage release for Swift is built with Xcode 15.4.0.
• CocoaPods: 1.10 or later.
• Xcode: 15.1.0-15.4.0.

v10.50.0

Drop support for Xcode 14, as it can no longer be used to submit app to the app
store. Xcode 15.1 is now the minimum supported version.

Known Issues

• Accessing App.currentUser within an App.subscribe callback would lead to a deadlock.

Enhancements

• Added SyncConfiguration.initialSubscriptions which describes the initial
  subscription configuration that was passed when constructing the
  SyncConfiguration. (#8548)
• When connecting to multiple server apps, a unique encryption key is used for
  each of the metadata Realms rather than sharing one between them
  (Core #7552).
• Improve perfomance of IN queries and chained OR equality queries for
  UUID/ObjectId types. (.Net #3566)
• Added support for updating Atlas Device Sync's base url, in case the need to roam between
  servers (cloud and/or edge server). This API is private and can only be imported using
  @_spi(Private)

  @_spi(RealmSwiftExperimental) import RealmSwift
  
  try await app.updateBaseUrl(to: "https://services.cloud.mongodb.com")

  (#8486).
• Enable building RealmSwift as a dynamic framework when installing via SPM, which
  lets us supply a privacy manifest. When RealmSwift is built as a static
  library you must supply your own manifest, as Xcode does not build static
  libraries in a way compatible with xcprivacy embedding. Due to some bugs in
  Xcode, this may require manual changes to your project:
  • Targets must now depend on only Realm or RealmSwift. If you use both the
    obj-c and swift API, depending on RealmSwift will let you import Realm.
    Trying to directly depend on both will give the error "Swift package
    target 'Realm' is linked as a static library by 'App' and 'Realm', but
    cannot be built dynamically because there is a package product with the
    same name."
  • To actually build RealmSwift as a dynamic framework, change "Do Not Embed"
    to "Embed & Sign" in the "Frameworks, Libraries, and Embedded Content"
    section on the General tab of your target's settings.
    (#8561).
• The transferredBytes and transferrableBytes fields on Progress have been deprecated
  in favor of progressEstimate which is a value between 0.0 and 1.0 indicating the estimated
  progress toward the upload/download transfer. (#8476)

Fixed

• -[RLMUser allSessions] did not include sessions which were currently
  waiting for an access token despite including sessions in other non-active
  states. (Core #7300, since v10.0.0).
• [RLMApp allUsers] included users which were logged out during the current
  run of the app, but not users which had previously been logged out. It now
  always includes all logged out users. (Core #7300, since v10.0.0).
• Deleting the active user (via User.delete()) left the active user
  unset rather than selecting another logged-in user as the active user like
  logging out and removing users does. (Core #7300, since v10.23.0).
• Fixed several issues around copying an encrypted Realm between platforms with
  different page sizes (such as between x86_64 and arm64 Apple platforms):
  • Fixed Assertion failed: new_size % (1ULL << m_page_shift) == 0 when
    opening an encrypted Realm less than 64Mb that was generated on a platform
    with a different page size than the current platform.
    (Core #7322, since v10.42.0)
  • Fixed a DecryptionFailed exception thrown when opening a small (<4k of
    data) Realm generated on a device with a page size of 4k if it was bundled
    and opened on a device with a larger page size (since the beginning).
  • Fixed an issue during a subsequent open of an encrypted Realm for some rare
    allocation patterns when the top ref was within ~50 bytes of the end of a
    page. This could manifest as a DecryptionFailed exception or as an
    assertion: encrypted_file_mapping.hpp:183: Assertion failed: local_ndx < m_page_state.size(). (Core #7319)
• Schema initialization could hit an assertion failure if the sync client
  applied a downloaded changeset while the Realm file was in the process of
  being opened (#7041, since v10.15.0).
• The reported download progress for flexible sync Realms was incorrect. It is now replaced by a
  progress estimate, which is derived by the server based on historical data and other heuristics.
  (#8476)

Enhancements

• The default base url in AppConfiguration has been updated to point to services.cloud.mongodb.com. See https://www.mongodb.com/docs/atlas/app-services/domain-migration/ for more information. (#8512)

Fixed

• Fixed a crash that would occur when an http error 401 or 403 is returned upon
  opening a watch stream for a MongoDB collection. (#8519)
• Fix an assertion failure "m_lock_info && m_lock_info->m_file.get_path() == m_filename" that appears to be related to opening a Realm while the file is in the process of being closed on another thread. (#8507)
• Fixed diverging history due to a bug in the replication code when setting default null values (embedded objects included). (Core #7536)
• Null pointer exception may be triggered when logging out and async commits callbacks not executed. (Core #7434)

Internal

• Upgraded realm-core from v14.3.0 to 14.4.1

v10.49.0

This version introduces a new Realm file format version (v24). Opening existing
Realm files will automatically upgrade the files, making them unable to be
opened by older versions. This upgrade process should typically be very fast
unless you have large Sets of AnyRealmValue, String, or Data, which have to be rewritten.

A backup will automatically be created next to the Realm before performing the
upgrade. Downgrading to older versions of Realm will attempt to automatically
restore the backup, or it will be deleted after three months.

Enhancements

• Storage of Decimal128 properties has been optimised similarly to Int
  properties so that the individual values will take up 0 bits (if all nulls),
  32 bits, 64 bits or 128 bits depending on what is needed.
  (Core #6111)
• Improve file compaction performance on arm64 platforms for encrypted files
  between 16kB and 4MB in size. (PR #7492).

Fixed

• Sorting on binary Data was done by comparing bytes as signed char rather than
  unsigned char, resulting in very strange orders (since sorting on Data was
  enabled in v6.0.4)
• Sorting on AnyRealmValue did not use a valid total ordering, and certain
  combinations of values could result in values not being sorted or potentially
  even crashes. The resolution for this will result in some previously-valid
  combinations of values of different types being sorted in different orders
  than previously (since the introduction of AnyRealmValue in 10.8.0).
• RLMSet/MutableSet was inconsistent about if it considered a String and a Data
  containing the utf-8 encoded bytes of that String to be equivalent. They are
  now always considered distinct. (since the introduction of sets in v10.8.0).
• Equality queries on a Mixed property with an index could sometimes return
  incorrect results if values of different types happened to have the same hash
  code. (Core 6407 since v10.8.0).
• Creating more than 8388606 links pointing to a single object would crash.
  (Core #6577, since v5.0.0)
• A Realm generated on a non-apple ARM 64 device and copied to another platform
  (and vice-versa) were non-portable due to a sorting order difference. This
  impacts strings or binaries that have their first difference at a non-ascii
  character. These items may not be found in a set, or in an indexed column if
  the strings had a long common prefix (> 200 characters).
  (Core #6670, since 2.0.0 for indexes, and since since the introduction of sets in v10.8.0)
• Fix a spurious crash related to opening a Realm on background thread while
  the process was in the middle of exiting (Core #7420).
• Opening a Realm with a cached user while offline would fail to retry some
  steps of the connection process and instead report a fatal error.
  (#7349, since v10.46.0)

Internal

• Upgraded realm-core from 13.26.0 to 14.3.0

v10.48.1

Fixed

• The Realm.framework privacy manifest was missing
  NSPrivacyAccessedAPICategoryDiskSpace, but we check free disk space before
  attempting to automatically back up Realm files (since 10.46.0).

Compatibility

• Realm Studio: 14.0.1 or later.

v10.48.0

Enhancements

• Lifted a limitation that would prevent declaring a model with only computed properties. (#8414)
• Add Xcode 15.3 to the release package (PR #8502).

Fixed

• Fix multiple arguments support via the REALM_EXTRA_BUILD_ARGUMENTS environment variable in build.sh. (PR #8413). Thanks, @hisaac!
• Fix some of the new sendability warnings introduced in Xcode 15.3 (PR #8502).

• CocoaPods: 1.10 or later.
• Xcode: 14.2-15.3.0.

v10.47.0

Enhancements

• Added initial support for geospatial queries on points. There is no new dedicated type to store Geospatial points, instead points should be stored as (GeoJson-shaped) embedded object, as the example below:

  public class Location: EmbeddedObject {
    @Persisted private var coordinates: List<Double>
    @Persisted private var type: String = "Point"
  
    public var latitude: Double { return coordinates[1] }
    public var longitude: Double { return coordinates[0] }
  
    convenience init(_ latitude: Double, _ longitude: Double) {
        self.init()
        // Longitude comes first in the coordinates array of a GeoJson document
        coordinates.append(objectsIn: [longitude, latitude])
    }
  }

  Geospatial queries (geoWithin) can only be executed on such a type of objects and will throw otherwise. The queries can be used to filter objects whose points lie within a certain area, using the following pre-established shapes (GeoBox, GeoPolygon, GeoCircle).

  class Person: Object {
    @Persisted var name: String
    @Persisted var location: Location? // GeoJson embedded object
  }
  
  let realm = realmWithTestPath()
  try realm.write {
    realm.add(PersonLocation(name: "Maria", location: Location(latitude: 55.6761, longitude: 12.5683)))
  }
  
  let shape = GeoBox(bottomLeft: (55.6281, 12.0826), topRight: (55.6762, 12.5684))!
  let locations = realm.objects(PersonLocation.self).where { $0.location.geoWithin(shape) })

  A filter or NSPredicate can be used as well to perform a Geospatial query.

  let shape = GeoPolygon(outerRing: [(-2, -2), (-2, 2), (2, 2), (2, -2), (-2, -2)], holes: [[(0, 0), (1, 1), (-1, 1), (0, 0)]])!
  let locations = realm.objects(PersonLocation.self).filter("location IN %@", shape)
  
  let locations = realm.objects(PersonLocation.self).filter(NSPredicate(format: "location IN %@", shape))

Internal

• Migrated Release pipelines to Github Actions.

v10.46.0

Enhancements

• Add a privacy manifest to both frameworks.
• Internal C++ symbols are no longer exported from Realm.framework when installing via CocoaPods, which reduces the size of the binary by ~5%, improves app startup time a little, and eliminates some warnings when linking the framework. This was already the case when using Carthage or a prebuilt framework (PR #8464).
• The baseURL field of AppConfiguration can now be updated, rather than the value being persisted between runs of the application in the metadata storage. (Core #7201)
• Allow in-memory synced Realms. This will allow setting an in-memory identifier on a flexible sync realm.

Fixed

• @Persisted's Encodable implementation did not allow the encoder to customize the encoding of values, which broke things like JSONEncoder's dateEncodingStrategy (#8425).
• Fix running Package.swift on Linux to support tools like Dependabot which need to build the package description but not the package itself (#8458, since v10.40.1).

Breaking Changes

• The schemaVersion field of Realm.Configuration must now always be zero for synchronized Realms. Schema versions are currently not applicable to synchronized Realms and the field was previously not read.
