Ahh, isn't Xcode great ?
啊，是不是 Xcode 很棒？
What I would recommend is this: Click on your project in the left panel, then check your architecture settings in both the Projectandthe Targetssections.
我建议是这样的：在左侧面板中，点击您的项目，然后在这两个检查你的架构设置项目和该目标部分。
And if you have any third-party projects within your project, do the same for them aswell.
如果您的项目中有任何第三方项目，也请对它们执行相同的操作。
(I had to do this when building an Xcode project which used the MapBox iOS SDKlibrary. Annoyingly, you doneed to check this setting in each of the various Build Settings tabs, otherwise Xcode will complain.)
（在构建使用MapBox iOS SDK库的 Xcode 项目时，我必须这样做。烦人的是，您确实需要在各个构建设置选项卡中检查此设置，否则 Xcode 会报错。）

Have you added the library path to Build Settings -> Libraries Search Path? Check at Build Settings -> Link Binary With Libraries that your library is added also.
您是否将库路径添加到 Build Settings -> Libraries Search Path？检查 Build Settings -> Link Binary With Libraries 是否也添加了您的库。

Go to Build Phases-> Link Binary with LibrariesAdd your third party library to this. If you could not find your library, click Add other.
转到Build Phases-> Link Binary with Libraries将您的第三方库添加到此。如果找不到您的库，请单击添加其他。
