Question

我正在尝试在真实项目中第一次使用Realm，并且我已成功通过Cocoapods添加它。我正在使用Xcode 6.4，但在同一台机器上安装了Xcode 7.1 beta（适用于其他项目）。

当尝试构建项目或运行单元测试时（在模拟器上），我收到一个链接器错误，说有数十对文件是重复的。看起来像一个提到Bitcode而一个没有。

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

我见过其他人谈论类似的问题，但没有使用Xcode 6.4，而不是简单地运行应用程序，而不是提交到商店。

我还应该指出，添加Realm作为静态框架（来自xcode-6的{{1}}文件夹是完美的，所以它与我从Cocoapods获得的构建有关，似乎

我可以在这做什么？如果可能的话，我真的宁愿从Cocoapods那里得到它。

根据您使用的Xcode版本，需要不同版本的Realm核心库，因此在运行{xcode-select时使用pod install激活相同版本非常重要1}}您将用于构建项目。由于下载了Xcode 7版本的库，您可能已经激活了该版本的Xcode。运行sudo xcode-select -s /Applications/Xcode.app/Contents/Developer（假设您已安装Xcode 6;根据需要进行调整），删除Pods目录，然后重新运行pod install。

您可以使用xcrun swiftc -v检查您有效的Xcode版本。
