当我用xCode运行我的应用程序时,所有加载并运行正常.当我加载仪器并使用活动监视器或分配的分析模板按记录时,它会加载并运行正常.但是,如果我使用Zombies或Leaks,应用程序会立即崩溃.我甚至都看不到它.然后我访问
xcode中的崩溃日志,尽管崩溃的原因是
例外类型:EXC_BAD_ACCESS(SIGSEGV)
例外类型:EXC_BAD_ACCESS(SIGSEGV)
由于每个报告都不同,因此几乎不可能调试原因.

所以我不再打电话了
StoreManager.getProductIdentifiersFromServer()
这会停止后续的调用
JSONParser.jsonURL(_:jsonType:)
然后应用程序崩溃了

似乎没关系我做什么或不做什么功能我得到了崩溃.在我看来,它是一个系统调用而不是我造成崩溃的那个.是仅仅是我还是仪器9.3对其他人的僵尸和/或泄漏?
解决方法
我有一个类似的问题,我解决了它选择空白模板而不是泄漏,然后我用屏幕右上角的按钮手动添加分配和泄漏.
它是在Xcode版本9.4(9F1027a)上解决的
