Boolean changes value before I can assign it - objective-c

Question

I have a curious problem where my boolean variable is changing before I can assign it to a variable to be read in my react native code for Spotify SDK.
I have pinpointed the EXACT location as to where it changes and I am currently trying to figure out why:
I have a boolean called isLoggedIn that is set equal to 1 if a successful login occurs. This variable then sets loggedIn to a boolean value which is sent to my React Native code:
else
{
// login successful
NSLog(#"What is the value of isLoggedIn %#", [self isLoggedIn]);
////THIS shows that isLoggedIn still equal to 1.
[self initializePlayerIfNeeded:[RNSpotifyCompletion onComplete:^(id unused, RNSpotifyError* unusedError) {
NSLog(#"What is the value of isLoggedIn right after %#", [self isLoggedIn]);
/////NOW the isLoggedIn variable is now equal to 0.
// do UI logic on main thread
dispatch_async(dispatch_get_main_queue(), ^{
[authController.presentingViewController dismissViewControllerAnimated:YES completion:^{
_loggingIn = NO;
NSLog(#"What is the value of isLoggedIn %#", [self isLoggedIn]);
NSNumber* loggedIn = [self isLoggedIn]; /////this is the line we need to be == 1
resolve(loggedIn);
if(loggedIn.boolValue)
{
[self sendEvent:#"login" args:#[]];
}
}];
});
}]];
}
So obviously I assume that it is due to this line right?:
[self initializePlayerIfNeeded:[RNSpotifyCompletion onComplete:^(id unused, RNSpotifyError* unusedError)
Which is running this method: initializePlayerIfNeeded but when I read the value of the isLoggedIn variable at the end of this method it still shows a boolean value of 1 (look at last line):
-(void)initializePlayerIfNeeded:(RNSpotifyCompletion*)completion
{
if(![self hasPlayerScope])
{
[completion resolve:nil];
return;
}
// ensure only one thread is invoking the initialization at a time
BOOL initializedPlayer = NO;
NSError* error = nil;
BOOL allowCaching = (_cacheSize.unsignedIntegerValue > 0);
#synchronized(_player)
{
// check if player is already initialized
if(_player.initialized)
{
initializedPlayer = YES;
}
else
{
initializedPlayer = [_player startWithClientId:_auth.clientID audioController:nil allowCaching:allowCaching error:&error];
}
}
// handle initialization failure
if(!initializedPlayer)
{
[completion reject:[RNSpotifyError errorWithNSError:error]];
return;
}
// setup player
_player.delegate = self;
_player.playbackDelegate = self;
if(allowCaching)
{
_player.diskCache = [[SPTDiskCache alloc] initWithCapacity:_cacheSize.unsignedIntegerValue];
}
// attempt to log in the player
[self loginPlayer:completion];
NSLog(#"What is the value of isLoggedIn %#", [self isLoggedIn]);
////THIS shows that isLoggedIn still equal to 1.
}
So that method finishes up with the value still equal to 1, but why after that method returns does the next line show that isLoggedIn equal to 0? I am extremely new to objC so every bit of knowledge is helpful for me. I am using this React Native Spotify library from github: https://github.com/lufinkey/react-native-spotify
You can find the exact file I'm working with here: https://github.com/lufinkey/react-native-spotify/blob/master/ios/RNSpotify.m
What else would you need to help solve this?
EDIT: here's the method that changes the isLoggedIn:
RCT_EXPORT_BLOCKING_SYNCHRONOUS_METHOD(isLoggedIn)
{
if(!_initialized)
{
return #NO;
}
else if(_auth.session == nil)
{
return #NO;
}
return #YES;
}
