Dear arshankhanifar thank you so much. I have lost spent the last couple of days trying to get high frame rate in my app. And only thank to persevering search did I eventually find your most valuable post. Thanks again
The documentation quote/page you are referring to has moved to Formats.
Also in this page inputPriority Apple is wrongfully stating:
When you change the device’s format, the session preset automatically changes to this value (inputPriority).

Thank you very much @arshankhanifar.
In addition, I have noticed (iPad Pro 9.7, iOS 16.2) that I have to configure the device's frame rate after having added the video input to the capture session. Otherwise, the device frame rate seems to be reset to some default values.
