网上有说添加的组件库中缺少plist文件、bundle ID重复的、证书问题、Xcode缓存问题等等，但排查后都没解决问题，包括删了Xcode缓存~/Library/Developer/Xcode/DerivedData目录下的文件后重新打包还是不行。

后面发现我在添加依赖库后把Embed改成了“Embed & Sign”或者“Embed Without Signing”：

实际上只需要把它改回“Do Not Embed”即可解决问题，如果非要Embed，那就在Build Phases -> Embedded Frameworks ->勾选 “Copy only when installing”：

另外遇到这种问题要根据具体的提示信息来排查问题，我这里是报“Could not inspect the application package.”，其他可能是“The maximum number of apps for free development profiles has been reached”或者“The certificate used to sign “XXX” has either expired or has been revoked. An updated certificate is required to sign and install the application.”等等，具体问题具体分析。
