ios - 代码 8 : Symbol(s) not found for architecture arm64 for pods

Question

更新到 Xcode 8 后，应用程序将无法在设备上运行，只能在模拟器上运行。为添加到项目的所有 pod 抛出错误:

Undefined symbols for architecture arm64:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

对于每个文件，还会抛出此警告:

file was built for archive which is not the architecture being linked (arm64)

事件架构没问题，我试过删除派生数据文件夹，重新安装 pod，将“仅构建事件架构”设置为"is"和“否”，但没有任何效果。

我的 Podfile 看起来像这样:

platform :ios, '8.0'
workspace 'Purple'
target 'Purple' do
pod 'AFNetworking', '2.6.3'
pod 'SAMKeychain', '~> 1.3'
pod 'TSMessages'
pod 'Facebook-iOS-SDK', '~> 3.23.2'
pod 'SWTableViewCell'
pod 'CardIO'
pod 'Parse'
pod 'PureLayout'
pod 'Branch'
pod 'DZNEmptyDataSet'
end

尝试清除 XCode 缓存:

rm -rf ~/Library/Developer/Xcode/DerivedData/

清除 CocoaPods 缓存并重新安装依赖项:

rm -rf "${HOME}/Library/Caches/CocoaPods"
rm -rf "`pwd`/Pods/"
pod update

最后转到“Pods”项目，并将“Debug”配置的“仅构建事件架构”设置为“否”。
