Multiple commands produce '/Users/joy/Library/Developer/Xcode/DerivedData/FKY-cpdtnacrrykispgfanfwxzyhrnge/Build/Products/Debug-iphonesimulator/FKY-TEST.app/Info.plist':
1) Target 'FKY-TEST' (project 'FKY') has copy command from '/Users/joy/Documents/1药网Git/fangkuaiyi_ios/FKY/FKYSwift/Vendor/SKPhotoBrowser/Info.plist' to '/Users/joy/Library/Developer/Xcode/DerivedData/FKY-cpdtnacrrykispgfanfwxzyhrnge/Build/Products/Debug-iphonesimulator/FKY-TEST.app/Info.plist'
2) Target 'FKY-TEST' (project 'FKY') has copy command from '/Users/joy/Documents/1药网Git/fangkuaiyi_ios/FKY/Supporting Files/Info.plist' to '/Users/joy/Library/Developer/Xcode/DerivedData/FKY-cpdtnacrrykispgfanfwxzyhrnge/Build/Products/Debug-iphonesimulator/FKY-TEST.app/Info.plist'
3) Target 'FKY-TEST' (project 'FKY') has process command with output '/Users/joy/Library/Developer/Xcode/DerivedData/FKY-cpdtnacrrykispgfanfwxzyhrnge/Build/Products/Debug-iphonesimulator/FKY-TEST.app/Info.plist'

报错原因：重复

方案一

修改 Xcode 的配置暂时解决了编译报错的问题。

Xcode -> File -> Workspace settings -> Build System，选择 Legacy Build System 。

方案二

  1. 选择打开所在的项目Target -> Build Phases -> Copy Bundle Resources
  2. 删除报错的那些文件

2. library not found for -lstdc++.6.0.9

Xcode10不支持libstdc++系列的库了、需要删掉并且换成libc++系列的库。有些第三方由于没有更新，会牵扯到这个库，所以运行后报错。

方案一

打开Build Phases -> Link Binary With Libraries，删除lstdc++.6.0.9依赖

有可能还有删除Build Setting -> Other Linker Flags里的-l"stdc++.6.0.9"

但是现在部分第三方SDK依旧要依赖于lstdc++.6.0.9.tbd动态库，如果对代码进行改动或者修改 Xcode 的配置，可能会造成其他问题，例如在Xcode9.4上再次运行的时候可能会出现报错等等。

方案二

最简单解决该问题的方法就是从 Xcode9.4 中找到动态库lstdc++.6.0.9.tbd、libstdc++.6.tbd、libstdc++.tbd文件复制到 Xcode10 下就可以完美解决问题。

  • 真机

    1
    /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/lib/

  • 模拟器

    1
    /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/usr/lib/

libstdc++文件下载链接

3. ld: symbol(s) not found for architecture x86_64

前面两个问题解决后，就遇到了这个问题，目前，在模拟器运行的时候会报这个错误，而使用真机运行的话没有问题，猜测应该是iOS12 模拟器的问题。
