ios - 在 macOS High Sierra 上获取默认 Realm 时崩溃

Question

我过早升级到 macOS High Sierra 犯了一个大错误。现在，每当我尝试通过简单地调用 let realm = try! 在模拟器中获取默认的 Realm 时。 Realm()，应用程序崩溃并显示以下跟踪信息。

)

我的安装如下:

• Xcode 9.0
• Cocoapods 1.3.1
• Realm 2.10.1
• swift 3.2
• SSD 硬盘，这意味着我有 APFS
• 启用文件保险箱

我试图在网上找到任何东西，显然什么都没有。
我也试过了(但是没用):

• 移除并重新安装 pod
• 删除 Realm 文件
• 在模拟器中删除并重新安装应用
• 删除 Xcode 的派生数据

Answer 1

显然，我非常短视(我确实活该 🙃)，这与我想的任何事情都无关。

通过Realm的代码调试检查异常，原来是这条指令引起的crash id propertyValue = [obj valueForKey:_name];在 [RLMProperty initSwiftPropertyWithName:indexed:linkPropertyDescriptor:property:instance:] 中。

实际问题是我添加了 Realm 不支持的 Decimal 类型的字段。
