I'd like to use the Xcode 9 beta new features but I'm worried about backwards compatibility after working with the beta version. I've had such problems with past Xcode beta versions (since it made storyboards unusable with previous versions). I've tried loading test projects (ObjC and Swift) without any problem but I'd like to know if someone here can confirm this point since I need to upload to App Store frequently and I'll need Xcode 8 to do it.
Thanks.
