我过早升级到 macOS High Sierra 犯了一个大错误。现在，每当我尝试Realm通过简单地调用来获得模拟器中的默认值时let realm = try! Realm()，应用程序都会崩溃并显示以下跟踪。

我的安装如下：

  • Xcode 9.0
  • Cocoapods 1.3.1
  • 领域 2.10.1
  • 斯威夫特 3.2
  • SSD 硬盘，这意味着我有 APFS
  • 文件保险箱已启用

我试图在网上找到任何东西，显然没有任何东西。
我也试过（但没用）：

  • 卸下和重新安装 pod
  • 删除领域文件
  • 在模拟器中删除并重新安装应用程序
  • 删除 Xcode 的派生数据

显然，我非常短视（我确实应该得到那些反对票），这与我的想法无关。

通过Realm's 代码调试异常，发现崩溃是id propertyValue = [obj valueForKey:_name];由[RLMProperty initSwiftPropertyWithName:indexed:linkPropertyDescriptor:property:instance:].

实际问题是我添加了一个Decimal不支持的类型字段Realm。
