iOS 9.1应用程序存在严重问题：我已更新应用程序，在多个iPhone设备上成功测试，将其提交到App Store，Apple审核并推出应用程序。该应用程序使用核心数据。
然而，问题是应用程序在启动后立即崩溃，以便将安装它的用户作为更新。下面列出了崩溃报告，但是，我无法找到它的真正问题（也因为并非所有内容都符号化）。如果我直接通过Xcode在同一台设备上运行它，那么该应用程序可以正常运行并且不会崩溃。
关于如何找到错误的任何想法？
非常感谢任何提示！

答案 0 :(得分：0)
以防其他人遇到此问题： 这个问题实际上是Swift实现数组的一个错误。以下代码在发布模式下崩溃：
myarr.sortInPlace($0.date < $1.date)
但是，这段代码很好用：
myarr = myarr.sort($0.date < $1.date)
