Error message : Reading from public effective user settings & System group container for path is

When I use the following code, I have error messages :

[NSURLConnection sendAsynchronousRequest:request queue:myQueue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
        NSLog(@"response status code: %ld, error status : %@", (long)[httpResponse statusCode], error.description);

        if ((long)[httpResponse statusCode] >= 200 && (long)[httpResponse statusCode]< 400)
               // do stuff
                [self requestFunction]; //Web Service

    The [self requestFunction] function launch a simple request :

            NSMutableURLRequest* request = [[NSMutableURLRequest alloc] init];
            NSString *url_string = [bytes stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
            [request setURL:[NSURL URLWithString:[set_send_order stringByAppendingString: url_string]]];
            [request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
            [request setTimeoutInterval:timeOut];
            [NSURLConnection connectionWithRequest:request delegate:self]; 

    I precise that the connectionDidFinishLoading: is not called, but if I launch it directly without the sendAsynchronousRequest:, it works.
    So why the fact that I use sendAsynchronousRequest: function makes me appear the two error messages, and the miscalling of the connectionDidFinishLoading ?

    Thank you in advance.

    It occurs to me. The same logs in console when I use textField. Follow is my operation:

    • From Xcode menu open: Product > Scheme > Edit Scheme
    • On your Environment Variables set OS_ACTIVITY_MODE in the value set disable

    I solved it thanks to this discussion.
