Cloudkit在获取用户记录ID时出错

Question

I'm creating an app that uses cloudkit and I'm getting an error that I don't understand this is my code:

CKContainer *defaultContainer =[CKContainer defaultContainer];
CKDatabase *publicDB = [defaultContainer publicCloudDatabase];
[defaultContainer fetchUserRecordIDWithCompletionHandler:^(CKRecordID *recordID, NSError *error) {
    if(error){
        NSLog([NSString stringWithFormat:@"1 %@", error.description]);}
    else{
        [publicDB fetchRecordWithID:recordID completionHandler:^(CKRecord *record, NSError *error) {
            if(error){
                NSLog([NSString stringWithFormat:@"2 %@", error.description]);}
            else{
                record[@"name"]=name.text;
                record[@"phone"]=phone.text;
                record[@"building"]=building.text;
                record[@"apartment"]=apartment.text;
                [publicDB saveRecord:record completionHandler:^(CKRecord *record, NSError *error) {
                    if(error){
                         NSLog([NSString stringWithFormat:@"3 %@", error.description]);}
                    else{
                         NSLog(@"success");}}];}}];}}];

and this is the error Im getting:

我注意到他们发布了XCode的Beta 4-我有beta 3，并且遇到了相同的错误-我现在正在下载新的XCode，看看是否能解决该错误。
