添加 Realm Cocoapod 时重复符号

Question

我第一次尝试在实际项目中使用Realm，我已经通过Cocoapods成功添加了它。我正在使用 Xcode 6.4，但在同一台机器上安装了 Xcode 7.1 beta（用于其他项目）。

尝试构建项目或运行单元测试（在模拟器上）时，我收到一个链接器错误，指出有数十对文件被复制。貌似一个提到了 Bitcode，一个没有。

我正在使用 Xcode 6.4 – 为什么它甚至知道 Bitcode？这是错误的一小部分示例：

我看到其他人在谈论类似的问题，但不是 Xcode 6.4，也不是简单地运行安装应用程序，而不是提交到商店。

我还应该指出，将 Realm 添加为静态框架（从 0.95.3 的 xcode-6 文件夹中可以完美地工作，所以这与我从 Cocoapods 获得的构建有关，好像。

我可以在这里做什么？如果可能的话，我真的宁愿从 Cocoapods 得到它。

根据您使用的 Xcode 版本，需要不同版本的 Realm 核心库，因此当您 [=25] 时，使用 xcode-select 激活相同版本很重要=] pod install 用于构建项目。由于下载了 Xcode 7 版本的库，您可能激活了该版本的 Xcode。运行 sudo xcode-select -s /Applications/Xcode.app/Contents/Developer（假设那是你安装了 Xcode 6 的地方；根据需要调整它），删除 Pods 目录，然后重新运行 pod install.

您可以通过 xcrun swiftc -v 查看您激活的 Xcode 版本。
