iOS崩溃,EXC_BREAKPOINT,没有Xcode 6.1的线索

Question

我通常能够解决崩溃,但在这里我不知道它来自哪里.

我使用解析,我只是在后台用完成块做一个请求.应用程序在简单的if条件下崩溃,我几乎无法识别任何内容,无法打印描述,...你有什么想法吗？一个起点？什么？Xcode 6.1真的很奇怪,似乎调试器有问题.

这是崩溃的日志:

这是iOS代码的示例:

var query = PFQuery(className: "_User")
query.whereKey("facebookId", containedIn: ids)

query.findObjectsInBackgroundWithBlock(){
    results, error in
        if var resultsvar = results? {
              self.functionToCall(resultsvar)
         }
 }

并且functionToCall崩溃了.

也许这可以帮助:

是的 ！！！调试器无法正常工作！我能够通过执行以下操作找到正确的行：在您认为应用程序崩溃的开头放置一个断点，一步一步进行，记住您经历过的最低行。即使调试器在另一行上崩溃，您正在查找的行也可能是最低的行。
