无法理解Crashlytics中的崩溃报告.

这是崩溃日志：

以及相关来源：

typealias CompletionHandler = (success: Bool) -> Void


func user_info(match:(Match?),completionHandler:CompletionHandler) {
    var tind_id = match!.tinder_id
    var user_url = "(USER_INFO_URL)(tind_id)"
    Alamofire.request(.GET,user_url,headers: ["X-Auth-Token": tinder_token],encoding: .JSON)
        .responseJSON { response in

            let json = JSON(response.result.value!)

            var result = json["results"]
            var distance = result["distance_mi"].intValue

            let realm = try! Realm()

            try! realm.write {
                match?.distance_km = round(Double(distance) / 0.62137)
            }

            completionHandler(success: true)
    }
}

我猜我在使用completionHandler时遇到了什么问题？但它不会发生在每个人身上.我无法重现崩溃,但我的一些用户正在获取它.

解决方法

同意@Uri和@matt – 如果你不知道do / catch语法,下面是这些行的实现方式：

do {
  let realm = try Realm()
  try realm.write {
    match?.distance_km = round(Double(distance) / 0.62137)
  }
}catch {
  print(error)
}
