App with haptics crashes on iPhone6

We added haptics to our app. Great feature, but we are now receiving complaints from users with the iPhone6 that the app is crashing. Looking for a way to avoid crashes on unsupported devices.

If we default the use of haptics to "off" can we avoid the crashes? Or is this crash going to happen simply by having haptics in the app.

I am not the programmer. I am a developer on the project.

You will have to assess if haptics is supported on your target platforms.
