I completely agree with the previous comments. Losing option-key two-finger touch simulation in Device Hub is a major regression. Trackpad pinch and rotation gestures are useful, but they cannot replace true multi-touch simulation. Two-finger taps, pans, and custom gestures are now impossible to properly test without a physical device. The previous option-key implementation was simple, fast, and extremely useful. Please bring it back, or provide an equivalent way to simulate multiple touch points in Device Hub!

Sorry, it may be late... but I wanted to add it's perfectly normal that, when running on an iPhone 7, the CHHapticEngine.capabilitiesForHardware() API returns false. The iPhone 7 has a built-in haptic engine but it's not accessible by the Core Haptics APIs. Like Apple said in a WWDC video, Core Haptics in supported by the iPhones 8 / X and later.
