While this process takes a few steps, it opens up a new world of third-party apps that can be installed without using the App Store. In order to install Xcode directly onto an iOS 9 device such as an iPhone, Mac OS X is required.

In any case, those with iOS 9 already installed can upgrade to iOS 9 beta 4 by following these instructions:
