I have an app in private which need to scan all applications and schemes and get it by using private API LSApplicationWorkspace defaultWorkspace
with others functio
i got same Apple Reject.
Apple Says
Your app uses or references the following non-public APIs:
LSApplicationWorkspace
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.
Solutions
To find out which library or code is causing this problem use the below code snipped.
1-) Open the terminal in macbook (cmd+ space) and than write terminal
2-) change the project directory with the below code
cd /Users/emreg/Documents/{your project url}
3-) To search appropriate word
grep -r LSApplicationWorkspace .
grep -r allApplications .
in my case, Blesh SDK has included LSApplicationWorkspace and allApplications keyword which is not permitted by Apple. When i upteded SDK, my problem is solved.
i hope, this answer will help someone.
