【问题描述】：
我正在尝试将 swift 库导入到我的 Objective C 程序中，因此我需要使用命令 use_frameworks！在 podfile 中。但是当我放置它时，我收到以下错误：

ld：找不到 -lNSLogger clang 的库：错误：链接器命令 退出代码 1 失败（使用 -v 查看调用）
到目前为止我尝试过但没有奏效的方法：
- 目标/构建设置 :: 启用位码：否
- 文件/工作区设置/派生数据箭头 :: 删除 DerivedData 文件夹，清空垃圾箱
- 目标/构建设置/测试主机 :: $(BUILT_PRODUCTS_DIR)/TargetName.app/TargetName
- 终端 :: pod deintegrate , pod install
- 清除，重建
这是我的 podfile：
use_frameworks!
platform :ios, '8.0'
abstract_target 'defaults' do
pod 'XCDYouTubeKit', '~> 2.5.3'
pod 'XCDLumberjackNSLogger', '~> 1.0.0'
pod 'MBProgressHUD', '~> 1.0.0'
pod 'QRCodeReaderViewController', '~> 4.0.2'
pod 'Firebase/Core'
pod 'Firebase/Messaging'
pod 'Fabric', '~> 1.7.6'
pod 'Crashlytics', '~> 3.10.1'
pod 'NSLogger'
target 'myApp'
end
