As of iOS 9, you no longer need to rely on a jailbreak if you want to run some of the apps that aren't available on the App Store. All you need is a Mac, Xcode 7, the code you wish to compile, an iOS device running iOS 9, a free developer account, and some time. If you have all of those things, then you can install apps on your iPhone or iPad without a paid developer account, and without a jailbreak.
Compiling apps using Xcode 7 is fairly straightforward, but if you've never done it before, it can be a bit tricky. In this post, I'll show you how to compile code using Xcode 7 and run it on your iOS 9 device. I'll also discuss some of the errors and issues that you might incur along the way.
