I have posted a question on https://developer.apple.com/forums/thread/724437
The apple staff Kmart offerred me very helpful suggestions. However, i cannot leave a comment below it ( i am confused now) Following the apple staff Kmart's instuction, i submit a feedback and request TSI with. a sample Xcode project on (https://github.com/orcas1202/sample_for_TSI)
However, TSI replied that it is still under investigation. So, i am here to find some support. Would you please take a look at the very sample project.
Thanks in advance.
