v4.1.4

v4.1.3

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

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

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

[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.

[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.

[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.

[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.

[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.

[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.
