tokenCount < maxCountIncludingZeroTerminator 断言（osx 10.9）

Question

通过 XCode 8 构建应用程序并在 Mavericks (OSX 10.9) 上运行应用程序时，我收到崩溃并显示以下错误：

Apple 确实在 XCode 8 Release notes 中特别提到了这一点，并附有以下详细信息：

资产目录

使用 Xcode 8 编译的应用程序和部署 iOS 7 的目标可能会在启动时崩溃，并带有以下断言：

断言失败：(maxCountIncludingZeroTerminator > 0 && tokenCount

要解决此问题，请将部署目标更新为 iOS 8.0 或更高版本，或将单个图像添加到具有 至少在图像集中指定了五个属性，例如：

• 缩放（1x、2x、3x）
• 成语（添加 iPad、iPhone 和通用资产）
• 方向（从左到右，从右到左）
• 宽度/高度类（任意和紧凑等）
• 内存（添加 1 GB 资产）
• 图形（添加金属 1v2 资产）

无需在代码中使用图像或添加 所有这些属性。 (27852391)

我尝试在项目中添加一些 3 倍缩放的图像，但我仍然收到相同的异常。根据文档，我只需要添加其中一个属性来解决问题，但是它似乎对我没有用。有没有其他人遇到过这个？有人有解决办法吗？

我创建了一个新图标并手动修改了 json 文件以包含以下内容：

    }
  ],
  "info" : {
    "version" : 1,
    "author" : "xcode"
  }
}

我实际上并没有在任何地方使用这个图标。这样就解决了问题。如果有人遇到此问题并需要它，我已上传图标 here。

Answer 2

在我的测试中（也针对 macOS 10.9），这仅在使用 Xcode 8 在 macOS 10.12 上构建时发生。

在macOS 10.11.6 上使用 Xcode 8 构建时不会发生启动时崩溃。

这对某些人来说可能是一种快速的解决方法，尽管根据 Xcode 发行说明，Kyle 的回答是确定的。 （我还没有测试过 Xcode 8.1beta）。

更新

在 macOS 10.12 上使用 Xcode 8.1b2 构建，行为与使用 Xcode 8.0 相同。 （下一次测试将在 10.12.1 beta 上构建）
