iOS App Rejected: app uses or references non-public APIs

Question

Guideline 2.5.1 - Performance - Software Requirements

Your app uses or references the following non-public APIs:

PrivateFrameworks/Pegasus.framework (PGHostedWindow)

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.

Can anyone please tell how I solve this error? I am not using Pegasus framework at all. And also which apis consider as non-public?

Answer 1

I think you have used the private framework. The file PGHostedWindow is of Pegasus.framework and may be this file has been used in your app.

You can see the following link which show which file are available in Pegasus.framework:-

https://github.com/JaviSoto/iOS10-Runtime-Headers/tree/master/PrivateFrameworks/Pegasus.framework

You can also see the list of Private Framework on GitHub in the following link:-

The non-public API refers to Apple API methods that are not documented and offered to the programmer.

Apple does not guarantee that this part of the API will work in future upgrades. These API can freely change this part.
