I downloaded iOS 11 on my device and want to continue testing my projects on my device but it wont work because it says that ios 11.0 may not support the version of Xcode I have (which is 8.3.3). I am assuming this is because I need to use the Xcode 9 (or 9.1 beta release) but I can't seem to find where I can download this at.
To get the Xcode 9 beta:
Downloads for Apple Developers here.
Download stable version here here.
