我正在嘗試在iOS Swift項目中使用Google Endpoints。重複的符號Apple Mach-O鏈接程序錯誤
我創建Python中的Hello World端點的項目，我，我按照這些說明來設置它在我的項目設置它AppEngine上每https://cloud.google.com/appengine/docs/python/endpoints/
：https://cloud.google.com/appengine/docs/python/endpoints/consume_ios#Python_Adding_required_files_to_your_iOS_project 我使用了Google+ API了。
我被卡在上面的第3步。爲了方便起見，我在這裏重新鍵入：
Your project needs to include the foo.h & foo_Sources.m files generated from ServiceGenerator, which you ran previously, where foo is your API name. Disabling ARC is not required for these files.
在Xcode中，我去添加文件和我添加的.h和.m文件。我也修改我的Bridging Header文件，並編輯我的Build Settings Header搜索路徑以包含正確的路徑。
當我嘗試建立，我得到這個錯誤：

ld: 9 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我的觀察：
它看起來像在.m文件的import語句引起的問題。我正在關注Google的文檔以獲取他們SDK的信件，所以我想知道這是否是Swift/Objective-C限制。我沒有看到有人能夠將它設置在Github上，雖然：https://github.com/soundTricker/swift-cloud-endpoint-sample
這裏是我的問題：
- 爲什麼會說「爲架構的ARMv7 9重複的符號」？我正在計算正好8個「重複符號」錯誤消息...
- 我在哪裏添加「-v」來查看調用？
- 這些.o文件是什麼？什麼是我需要修復的9個重複符號？
- 我在想辦法解決這個問題，就是用我的Google Endpoints API文件創建一個框架。這樣，我只能在我的項目中包含.h文件。這是一個壞主意嗎？
僅供參考：我使用Google的代碼完全從他們的Github存儲庫克隆出來，以排除我的代碼存在的任何問題。即使在一個乾淨的項目中，我也會遇到同樣的問題我正在使用Xcode v.6.3.1。
