Fabric and Digits pods Xcode 7 和 Swift 2.0 中的失败工作区

Question

我更新到 Xcode 7 并修复了 Swift 2.0 的必要代码（语法）更改。我用这 2 个条目更新了我的 Podfile：

  pod 'Fabric'
  pod 'Digits'

现在看到许多构建错误（粘贴在下面）。有什么想法吗？

我运行sudo gem install cocoapods更新我的Cocoapods，然后运行pod install和pod update安装'Fabric' 和 'Digits' pods。

注意：在更新到 Xcode 7 之前，我使用 Digits 的项目可以正常构建和运行！

我认为问题在于您没有将 'TwitterCore' 包含到 pod 文件中：

pod 'Fabric'
pod 'Digits'
