在Xcode 9提交应用，报缺失App Store 图标错误：
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 iTunes Connect, apps cannot be submitted for App Review or Beta App Review
这是因为在Xcode 9需要App Store iOS 1024pt的PNG图标。
1、进入Assets.xcassets
2、滚动到图标集的底部找到
3、上传1024x1024px的图标
