[[self sharingDictionary] enumerateKeysAndObjectsUsingBlock: ^(id key,id obj,BOOL *stop) {
                    SharingElement* element=[[self sharingDictionary] objectForKey:key];
                    if (!element.confirmed){
                        dispatch_async(dispatch_get_main_queue(),^{
                            [element deleteMe];
                        });
                        [[self sharingDictionary] performSelector:@selector(removeObjectForKey:) withObject:key
                                                       afterDelay:.2];
                    } else{
                        element.confirmed=NO;
                }];

所以我尝试以这种方式使用以下紧凑的enumerated()方法：

for (key,element) in self.sharingDictionary.enumerated(){
            if (!element.confirmed){
                    element.deleteMe()
                self.perform(#selector(self.removeSharingInArray(key:)),with:key,afterDelay:0.2);
            } else{
                element.confirmed=false
            }
        }

然而,编译器在处理变量’element’的使用时报告以下错误：

Value of tuple type ‘(key: Int,value: SharingElement)’ has no member
‘confirmed’

像’元素’一样,完整的元组父亲胜过其能力.
是使用enumerated()或在字典处理中的问题,我该如何解决？
