CloudKit public database reading without iCloud login

Question

In the documents it says that CloudKit public databases will be available to read even if the user did not login with a proper iCloud account. However, I cannot fetch anything from my cloud database if i didn't connect my iOS simulator or device to iCloud. When i activate my iCloud account I am able to fetch data from my public database. If anyone who has an answer or same problem with me could answer that would be great. Thanks.

CKDatabase *publicDatabase = [[CKContainer containerWithIdentifier:@"mycontainer"] publicCloudDatabase];
CKRecordID *recordID = [[CKRecordID alloc] initWithRecordName:@"idofmyrecord"] ;

[publicDatabase fetchRecordWithID:recordID completionHandler:^(CKRecord *fetchedRecord, NSError *error) {
    if(!error){
        NSLog(@"****Success***** %@",fetchedRecord[@"field1"]);

    }else{
        NSLog(@"****Failed***** %@",fetchedRecord[@"field2"]);

    }
}];

Answer 1

The public database is only readable with no login in the production environment, not in the development environment.

Apple's documentation says:

In development, when you run your app through Xcode on a simulator or a device, you need to enter iCloud credentials to read records in the public database. In production, the default permissions allow non-authenticated users to read records in the public database but do not allow them to write records.
