调用getAllCookies()
崩溃只能在iOS 11.3.1的真实设备上重现。在模拟器上工作正常。
let httpCookieStore = WKWebsiteDataStore.default().httpCookieStore
httpCookieStore.getAllCookies { (cookies) in
}
Xcode控制台崩溃说：
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSURL length]: unrecognized selector sent to instance 0x10fc42790'
Crashlytics的崩溃：

Calling getAllCookies asynchronously in the main thread，不解决问题。
答案 0 :(得分：-2)
在崩溃日志中，您似乎正在访问length对象上的NSURL属性，并且NSURL对象没有length属性。这就是崩溃的原因。
您可能在app中的某个位置获得了字符串长度，但该对象的类型为NSURL。请调试它并放置异常断点以确定崩溃的确切位置。
