Question

我看到很少有用户崩溃，但Alamofire响应处理程序中却崩溃了。任何帮助表示赞赏。

感觉可能取决于服务器端的结果，但是我无法查明哪个结果可能是错误的……并且鉴于所有解析都在try catch中，所以我不清楚为什么会崩溃。

这是报告为EXC_BREAKPOINT的堆栈：

使用Swift 5面向iOS 11构建主要应用以及Alamofire Pods。AlamofireObjectMapper正在使用Swift 4构建

使用以下Pod：

- Alamofire (4.8.2)
  - AlamofireImage (3.5.2):
    - Alamofire (~> 4.8)
  - AlamofireNetworkActivityIndicator (2.4.0):
    - Alamofire (~> 4.8)
  - AlamofireNetworkActivityLogger (2.4.0):
    - Alamofire (~> 4.8)
  - AlamofireObjectMapper (5.2.0):
    - Alamofire (~> 4.7)

我有同样的问题。就我而言，这仅在我使用“数据”结构时发生。控制台输出错误如下

malloc: can't allocate region
*** mach_vm_map(size=920813568) failed (error code=3)
malloc: *** set a breakpoint in malloc_error_break to debug

“ malloc：无法分配区域”与内存泄漏问题有关。

在Alamofire DownloadRequest.dataResponseSerializer行+ 320中看到断点崩溃
