To learn more about the diffing process that SwiftUI applies, take a look at my “You have to change mindset to use SwiftUI” post. For example, try to avoid creating DateFormatter inside the body property. Don’t create heavy objects inside the body property. You should keep your body properties as fast as possible. The most interesting value here is the Average Duration. For example, when you change the value of the state or observed object. SwiftUI calls body property whenever view dependencies change. As you already know, SwiftUI calls the body property of your views to understand changes in the view hierarchy and render them. By understanding the values in these sections, you can investigate the issues that your app might have. SwiftUI profiling template is divided into four main sections: View Body, View Properties, Core Animation Commits, Time Profiler. Then you can select the SwiftUI template in the newly opened Instruments window and press the record button. Remember that you should profile your app only on the real device and not the simulator. Profiling your app by making incremental changes is the best way to identify and fix small performance downgrades.įirst of all, you need to build the app in profiling mode by selecting Product -> Profile or pressing CMD+I. I suggest you profile your apps on a weekly or bi-weekly basis. That’s why Instruments looks like the hidden gem of Xcode. Many developers profile apps only when they have some issues. This week we will learn how to profile SwiftUI apps using the SwiftUI template. It provides many profiling templates for debugging Core Data, catching memory leaks, disk read/writes, and much more. The Instruments app is a great tool for profiling your iOS apps. One of these tools is the Instruments app. Xcode comes with a bunch of tools you need to build, debug and release your apps.
