前天使用最新版的Xamarin Forms 4.4提交应用后，今天Apple审核返回信息如下：
Guideline 2.5.1 – Performance – Software Requirements

Your app uses or references the following non-public APIs:
– LinkPresentation.framework
– QuickLookThumbnailing.framework
The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change.
Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.
Next Steps
If you are using third-party libraries, please update to the most recent version of those libraries. If you do not have access to the libraries’ source, you may be able to search the compiled binary using the “strings” or “otool” command line tools. The “strings” tool can output a list of the methods that the library calls and “otool -ov” will output the Objective-C class structures and their defined methods. These tools can help you narrow down where the problematic code resides. You could also use the “nm” tool to verify if any third-party libraries are calling these APIs.

 

意思是用到了未经允许的两种Framework：

LinkPresentation.framework

QuickLookThumbnailing.framework

这是代码链接器造成的，解决办法：

选中iOS项目右键【属性】【iOS生成】在添加mtouch参数中加入【–linkskip=Xamarin.Essentials】，然后重新打包ipa，提交！
