Found another issue also. Add a UISlider inside a UIScrollView. Then just touch and release the slider thumb. The events that are received are: touchUpInside/touchUpOutside valueChanged touchDown What is happening is that we receive that we have a touch down after we received the touch up -> you cannot init some code in the touch down because no touch up will come and the state of the code is broken. I reported the issue to Apple at FB20388909

I have the same issue in my project. We have always used UIEvent and it had always worked. Now we always get nil. What are the official guidelines now? How are we supposed to use this API? It seems like a bug in the framework and the responsible Apple team should fix it.

I'm having the exact same issue on my Intel mac. I managed to install the watchOS 26.0 beta 5 component but the Simulator runtime fails. Tried restarting the mac & Xcode nothing works.
