# Checking the availability of 3D Touch

Check whether a device supports 3D Touch before enabling features that use it.

## Overview

Overview To determine if 3D Touch is available on a device, check the forceTouchCapability property of any object — such as your app’s views and view controllers — that adopts the UITraitEnvironment protocol. The following code shows how you might use this property to enable or disable features at load time from your view controller. Use the traitCollectionDidChange(_:) method to detect changes to 3D Touch availability while your app is running. class ViewController: UIViewController {     override func viewDidLoad() {         super.viewDidLoad()           // Check the trait collection to see if force is available.         if self.traitCollection.forceTouchCapability == .available {             // Enable 3D Touch features         } else {             // Fall back to other non-3D Touch features.         }     }       override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {         // Update the app's 3D Touch support.         if self.traitCollection.forceTouchCapability == .available {             // Enable 3D Touch features         } else {             // Fall back to other non-3D Touch features.         }     } } For guidance on how to implement your app both with and without 3D Touch support, see iOS Human Interface Guidelines.
