ios - swift 警告 : A lonng-running operation is being executed on the main thread

Question

您好，请帮我解决这个问题!

我得到这个输出:

第一个输出是:仅(lldb)!

直到我按“继续程序执行”三次，然后我得到了这个:

Warning: A lonng-running operation is being executed on the main thread.

Break on WarnBlockingOperationOnMainThread() to debug.

fatal error: unexpectedly found nil while unwrapping an Optional value

(lldb)

我认为这段代码的问题是:

let predicate = NSPredicate(format: "username != '"+userName+"'")var query = PFQuery(className: "_User", predicate: predicate)var objects = query.findObjects()for object in objects {self.resualtprofilename.append(object["profileName"] as String)self.rtable.reloadData()}

请帮我解决这个问题!我讨厌(lldb)它总是困扰我，我不知道这是什么意思。
