Xcode11.3更新后有坑，这。。。 已经习惯了。。。
到现在我还是用的Xcode10.3 打包上传，不知道落伍了没，不过问过身边好几个都这样哦，因为升级的坑还是有不少的。赶进度的，就不要升级了。但是我还是手残没忍住，加班fix吧~ 。当然做好了另一手打算，同时下载Xcode 10.3的xip文件，无奈网速虽然很快，但是解压着实很慢~
本来有Xcode10_3、Xcode(11.1)两个版本在Applications文件夹里，但是同意自动更新后，更新完后只剩下一个Xcode了Version 11.3 (11C29)
build原工程 error:
下面的错误 发生在3处
xcrun: error: unable to locate xcodebuild, please make sure the path to the Xcode folder is set correctly!
xcrun: error: You can set the path to the Xcode folder using /usr/bin/xcode-select -switch
设置Xcode -> File -> Project Settings/Workspace Setting -> Build System -> Legacy Build System 貌似解决了
再build冒出另一个问题
xcrun: error: unable to locate xcodebuild, please make sure the path to the Xcode folder is set correctly!
xcrun: error: You can set the path to the Xcode folder using /usr/bin/xcode-select -switch
Can't exec "": No such file or directory at /Applications/Xcode.app/Contents/Developer/usr/bin/copypng line 89.
ERROR: Failed to run -q -iphone -f 0 -rem text /Users/dl/Desktop/gitFiles/drbb/dplp/dplp/Vendors/Ali_FILE_SDK/AlivcShortVideo/AlivcShortVideoResource/ShortVideoResource/tail.png /Users/dl/Library/Developer/Xcode/DerivedData/dplp-bxmhpryjhamrkvaexzndhmvytatu/Build/Products/Debug-iphoneos/dplp.app/tail.png
Command /Applications/Xcode.app/Contents/Developer/usr/bin/copypng failed with exit code 255
在build phases 搜索 .png，将*.png都删掉。
又发现另一个error
codesign_allocate: error: unable to locate xcodebuild, please make sure the path to the Xcode folder is set correctly!
codesign_allocate: error: You can set the path to the Xcode folder using /usr/bin/xcode-select -switch
/Users/dl/Library/Developer/Xcode/DerivedData/dplp-bxmhpryjhamrkvaexzndhmvytatu/Build/Products/Debug-iphoneos/dplp.app/Frameworks/AlivcConan.framework: the codesign_allocate helper tool cannot be found or used
Command /bin/sh failed with exit code 1
参考 the codesign_allocate helper tool cannot be found or used
做法
把自己最新Xcode版本中的codesign_allocate（我这里的是"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate"中的"codesign_allocate"）复制到 /usr/bin/下 如果提示已经有的话直接选择替换即可，就解决了
终于能跑起来了
