Step	What to do	Why it matters
1	Open the Mac App Store, search for Xcode, and install it.	This installs the core Apple development environment.
2	Launch Xcode once, accept the license agreement, and enter the administrator password if prompted.	Xcode installs additional required components on first launch.
3	Open Xcode > Settings > Components, then install both visionOS and visionOS Simulator under Platform Support.	These platform packages are required to build and preview visionOS apps.
