添加Realm時添加重複符號Cocoapod

Question

我想在Real項目中第一次使用Realm，並且已經通過Cocoapods成功添加了它。我使用Xcode 6.4，但在同一臺機器上安裝了Xcode 7.1 beta（用於其他項目）。

當試圖構建項目或運行單元測試（在模擬器上）時，我得到一個鏈接器錯誤，指出幾十對文件是重複的。看起來像一個提到的位碼，一個沒有。

我正在使用Xcode 6.4 - 爲什麼它甚至知道Bitcode？下面是錯誤的一個小樣本：

我看到其他人在談論類似的問題，但不是在Xcode 6.4，而不是簡單地與運行應用程序，而不是提交給商店。

我還要指出的是，加入域作爲靜態框架（從0.95.3作品xcode-6文件夾完美，所以它是與我是從的CocoaPods得到構建，它似乎。

能有什麼如果可能的話，我真的寧願從Cocoapods那裏得到它

根據您使用的Xcode的版本，需要不同版本的Realm核心庫，所以重要的是要激活相同的版本當您運行pod install時，您將使用xcode-select來構建項目。由於Xcode 7版本的庫是下載，你可能有這個版本的Xcode活躍。運行sudo xcode-select -s /Applications/Xcode.app/Contents/Developer（假設您已安裝Xcode 6;必要時進行調整），刪除Pods目錄，然後重新運行pod install。

您可以檢查您使用xcrun swiftc -v激活的Xcode版本。
