Follow these steps: Download and install Xcode 11 Beta (You do NOT need to update your MacOs to Catalina) Download the iOS 13 Beta 1 IPSW for your iPhone model from the Internet. Connect your iPhone to your computer using a cable Open Xcode > create a new project > give the project a name, click ok. When done you should see your iPhone at the top of the Xcode window. Go to iTunes, Option + Check for update > browse to the IPSW you downloaded. On first boot up iOS may act a little weird (maps wouldn't display for me initially). I waited a few minutes and restarted and everything was fine.
