EXC_BAD_ACCESS. Completion block - ios

Question

ANSWER
I heve a mistake when i call the fetchDailyForecast it should looks like
[self.fetchController fetchDailyForecast:self.currentLocation.coordinate completionBlock:^(DailyModel *newModel) {
_dailyCondition = newModel;
NSLog(#"newModel = %#", _dailyCondition);
}];
END
I try to use bloc's and wait but have a bad_access exaction. Firstly i call method from MangeDataController.m
[self.fetchController
fetchDailyForecast:self.currentLocation.coordinate
completionBlock:(void(^)(DailyModel *))_dailyCondition];
where the dailyCondition is instance of DailyModel.
Secondly here is fetchDailyForecast method realization in FetchController.m.
-(void)fetchDailyForecast:(CLLocationCoordinate2D)coordinate completionBlock:(void(^)(DailyModel *))completionBlock {
NSString *urlString = [NSString stringWithFormat:#"http://api.openweathermap.org/data/2.5/forecast/daily?lat=%f&lon=%f&units=imperial&cnt=7%#", coordinate.latitude, coordinate.longitude, _key];
urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
[self fetchJSONfromURL:urlString completionBlock:^(NSDictionary *weatherData) {
completionBlock([[DailyModel alloc] dataFromDictionaryDaily:weatherData]); --- (here the bad access);
}];
}
and thirdly in fatchDailyForecast i call fetchJSONfromURL here is realization:
-(void)fetchJSONfromURL:(NSString *)urlString completionBlock:(void (^)(NSDictionary *))completionBlock {
NSLog(#"url = %#", urlString);
[_manager GET:urlString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responceObject) {
if (responceObject) {
completionBlock(responceObject);
} else {
NSLog(#"responce object error");
}
}
failure:^(NSURLSessionTask *operation, NSError *error){
NSLog(#"error %#", error);
}];
}
P.S. I think my mistake is that i try to pass day _dailyCondition but should pass something different. Thanks for any help!

EDIT 2
I add the condition into (void)fetchDailyForecast:(CLLocationCoordinate2D)coordinate completionBlock:(void(^)(DailyModel *))completionBlock and now app don't crash but it's still not work and nslog say #"nothing"
[self fetchJSONfromURL:urlString completionBlock:^(NSDictionary
*weatherData) { if (completionBlock) { completionBlock(model = [[DailyModel alloc] dataFromDictionaryDaily:weatherData]); } else {
NSLog(#"nothing"); } }];
