Adding Custom App to iPhone

Hello, I'm not new to programming, but am new to developing for Apple products. I'm planning on developing an app for my iPhone exclusively for my use. My question is can I add my custom app to my phone without having to go through the App Store? If I can avoid the App Store, how do I go about getting the app onto my phone? I do have Xcode and have learned Swift, so I just need to understand how to get the app onto my phone. Thank you for your help!
