Memory leak in [RCNConfigFetch URLSessionDataTaskWithContent:completionHandler:] (retain cycle)

Steps to reproduce:

Executing Firebase config initialization and fetching of remote config data

Relevant Code:

In application:didFinishLaunchingWithOptions: [FIRApp configure]; self.remoteConfig = [FIRRemoteConfig remoteConfig]; FIRRemoteConfigSettings *remoteConfigSettings = [[FIRRemoteConfigSettings alloc] initWithDeveloperModeEnabled:YES]; self.remoteConfig.configSettings = remoteConfigSettings;

long expirationDuration = 3600; weak typeof (self)weakSelf = self; [self.remoteConfig fetchWithExpirationDuration:expirationDuration completionHandler:^(FIRRemoteConfigFetchStatus status, NSError *error) { strong typeof (weakSelf) strongSelf = weakSelf; if (status == FIRRemoteConfigFetchStatusSuccess) [strongSelf.remoteConfig activateFetched]; }];

This looks like an issue that was reported here and subsequently fixed, but has not yet been released. @chliangGoogle can you make sure this makes its way into M31?

[charlotteliang]

I think this has just released in M30.

@marat643 can you try with Firebase 5.5.0 and see if you still have the leak?

[MaratIbragimov]

Yes, Thank you very much, it solved the issue, there is another leak in [APMUserDefaults objectForKey:], but I saw that you are handling it in another opened issue, so I'll wait for the next release.

Thank you once again :)

I concur that there still is another leak in [APMUserDefaults objectForKey:]
