Class method not being called in Obj C - ios

Question

Here is where I call the class method. The call is made after a NSURLRequest is finished. All values are there, nothing is nil
[MemberInfo SetMemberInfo:memberId groupId:groupId token:token withContext:_context];
Here is the method implemented in the class generated by the core data "MemberInfo+CoreDataProperties.m"
+ (bool)SetMemberInfo:(NSString *)memberId groupId:(NSString *)groupId token:(NSString *)token withContext:(NSManagedObjectContext *)context
{
NSManagedObject *memberInfoObject = [NSEntityDescription insertNewObjectForEntityForName:#"MemberInfo" inManagedObjectContext:context];
[memberInfoObject setValue:memberId forKey:#"memberId"];
[memberInfoObject setValue:groupId forKey:#"groupId"];
[memberInfoObject setValue:token forKey:#"token"];
NSError *error = nil;
if (![context save:&error])
{
return false;
}
return true;
}
I have zero errors, and nothing in the logs that explains why. But this class method 'SetMemberInfo' is never hit. Any clues?
EDIT **
Full code where I call method
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (error == nil)
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if ([httpResponse statusCode] == 200)
{
id object = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
if ([object isKindOfClass:[NSDictionary class]] && error == nil)
{
NSString *groupId = _tfGroupId.text;
NSString *memberId = _tfMemberId.text;
NSString *token = [object valueForKey:#"token"];
[MemberInfo SetMemberInfo:memberId groupId:groupId token:token withContext:_context];
}
}
}
}];
[postDataTask resume];

Must be something to do with the class that I has the class method in. I moved it to another class and it now makes the call.
