AirPlay on an iPhone is primarily accessed through the Control Center. Here's how you can find and use it:

• Access Control Center:
  • On iPhone X or later (and iPads with iPadOS 13 or later), swipe down from the top-right corner of the screen.
  • On iPhone 8 or earlier, swipe up from the bottom edge of the screen.
• Find AirPlay:
  • Look for the "Screen Mirroring" option or the AirPlay icon, which looks like a rectangle with a triangle pointing up.
  • Tap it to see a list of available AirPlay-compatible devices (like Apple TV or smart TVs) on the same Wi-Fi network.
• Use AirPlay:
  • Select the device you want to stream or mirror your screen to.
  • If prompted, enter the AirPlay passcode shown on the target device.

Additionally, some apps (like Photos or Music) have their own AirPlay buttons within the app interface for streaming content directly. You can also find AirPlay settings in the iPhone's Settings app under General > AirPlay & Handoff, where you can adjust AirPlay preferences. In summary, AirPlay is not a standalone app but a feature integrated into the Control Center and certain apps, and its settings are under General in the Settings app
