In this Xcode tutorial, you'll get familiar with the development environment where you’ll build apps in. I’ll show you where to get Xcode and how to start a new App project. Then we’ll walk through the major areas of Xcode. I’ll explain to you what each of the files in your new project is for and we’ll end the lesson with some tips on navigating around in Xcode.
This week, I want to talk about one of the most powerful Xcode features, SwiftUI previews.

Xcode comes with a bunch of tools you need to build, debug and release your apps. One of these tools is the Instruments app. The Instruments app is a great tool for profiling your iOS apps. It provides many profiling templates for debugging Core Data, catching memory leaks, disk read/writes, and much more. This week we will learn how to profile SwiftUI apps using the SwiftUI template.
