Status Bar

Status Bar design in Adobe XD/Sketch should be removed, projects should use a system-provided status bar.

When you have a Status Bar in the design, you can convert it to a Status Bar component to prevent its generation in your code. Mobile users expect the status bar to be consistent systemwide so you should use a system-provided status bar. You can do your edits/configuration after you export your project.

The Status Bar shouldn't be in the design.
