“can I do it with xcode 9?”
I’m not 100% sure about Xcode 9 beta, but previously you were not able to submit to the App Store using beta versions of Xcode. You’d receive an error stating:
INFO ITMS-90111: “Your app is built with a beta version of Xcode or
iOS SDK. Only apps distributed for beta testing may be built with beta
software. To submit an app for distribution on the App Store, you will
need to build the app with release versions of Xcode and iOS SDK.”
