Dear Developer,
We identified one or more issues with a recent delivery for your app, "***". Please correct the following issues, then upload again.
Invalid Signature - A sealed resource is missing or invalid. The file at path [***.app/***] is not properly signed. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target. For more information, please consult https://developer.apple.com/library/ios/documentation/Security/Conceptual/CodeSigningGuide/Introduction/Introduction.html
我是xcode 10.2.1
第一 最简单的错误 ，就是证书错误，这我就不做详细的解答
第二 检查自己是不是release模式
第三清除 缓存
~/资源库/Developer/Xcode/DerivedData
第四 检查自己的文件，图片是否存在特殊符号字符 （仔细仔细仔细检查）
我这边是因为有一个文件夹是在svn 上导下来，就出现乱码
名字修改了就行了
