If you refer to your emulator host by IP rather than by domain name, you may also need to specify a namespace ("http:///?ns="). (#3491)

  v5.0.2

  • [fixed] Fixed undefined behavior sanitizer issues. (#1443, #1444)

  v4.1.5

  • [fixed] Fixes loss of precision for 64 bit numbers on older 32 bit iOS devices with persistence enabled.
  • [changed] Addresses CLANG_WARN_OBJC_IMPLICIT_RETAIN_SELF warnings that surface in newer versions of Xcode and CocoaPods.

  v4.1.4

  • [added] Firebase Database is now community-supported on tvOS.

  v4.1.3

  • [changed] Internal cleanup in the firebase-ios-sdk repository. Functionality of the RTDB SDK is not affected.

  v4.1.2

  • [fixed] Addresses race condition that can occur during the initialization of empty snapshots.

  v4.1.1

  • [fixed] Fixed warnings for callback types with missing argument specifications in Xcode 9.

  v4.1.0

  • Added multi-resource support to the database SDK.

  v4.0.3

  • [fixed] Fixed a regression in v4.0.2 that affected the storage location of the offline persistent cache. This caused v4.0.2 to not see data written with previous versions.
  • [fixed] Fixed a crash in FIRApp deleteApp for apps that did not have active database instances.

  v4.0.2

  • [fixed] Retrieving a Database instance for a specific FirebaseApp no longer returns a stale instance if that app was deleted.
  • [changed] Added message about bandwidth usage in error for queries without indexes.

  v4.0.1

  • [changed] We now purge the local cache if we can't load from it.
  • [fixed] Removed implicit number type conversion for some integers that were represented as doubles after round-tripping through the server.
  • [fixed] Fixed crash for messages that were send to closed WebSocket connections.

  v4.0.0

  • [changed] Initial Open Source release.

  v3.1.2

  • [changed] Removed unnecessary _CodeSignature folder to address compiler warning for "Failed to parse Mach-O: Reached end of file while looking for: uint32_t".
  • [changed] Log a message when an observeEvent call is rejected due to security rules.

  v3.1.1

  • [changed] Unified logging format.

  v3.1.0

  • [feature] Reintroduced the persistenceCacheSizeBytes setting (previously available in the 2.x SDK) to control the disk size of Firebase's offline cache.
  • [fixed] Use of the updateChildValues() method now only cancels transactions that are directly included in the updated paths (not transactions in adjacent paths). For example, an update at /move for a child node walk will cancel transactions at /, /move, and /move/walk and in any child nodes under /move/walk. But, it will no longer cancel transactions at sibling nodes, such as /move/run.

  v3.0.3

  • [fixed] Fixed an issue causing transactions to fail if executed before the SDK connects to the Firebase Database backend.
  • [fixed] Fixed a race condition where doing a transaction or adding an event observer immediately after connecting to the Firebase Database backend could result in completion blocks for other operations not getting executed.
  • [fixed] Fixed an issue affecting apps using offline disk persistence where large integer values could lose precision after an app restart.
