xcode上架应用，审核过了，构建版本没有，邮件内容！

Dear Developer,

We identified one or more issues with a recent delivery for your app, "****". Please correct the following issues, then upload again.

Invalid package - Applications built with sdk 9.0 or later must be packaged as proper IPA files.

Though you are not required to fix the following issues, we wanted to make you aware of them:

Missing App Store Icon - iOS Apps must include a 1024x1024px App Store Icon in PNG format. Without providing the icon in the Asset Catalog or via App Store Connect, apps cannot be submitted for App Review or Beta App Review. Refer to https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/app-icon/ for more information.

SDK Version Issue - This app was built with the iOS 11.2 SDK. Starting March 2019, all iOS apps submitted to the App Store must be built with the iOS 12.1 SDK or later, included in Xcode 10.1 or later.

Best regards,

The App Store Team

图标的话 我确实是1024*1024的jpg的，还有报错是说sdk版本太低？我用sdksuit_4.0_170122_01_Xcode8.1

嗯，您这用的引擎版本是够低的，您换成最新版本的引擎，重新打包试试吧
