I have been having this issue when I build an app for work since using Xcode 16/16.1. If I build it with Xcode 15.4, there is no issue. I'm glad that long pressing works but agree it isn't ideal. I'm hoping for a fix as well. If I press other buttons or textfields that work, sometimes the unresponsive buttons may come back but others may break. Edit: My devices (iPhone and iPad) are running their respective 18.1 beta 6 OSes but has been an issue since only since building with Xcode 16/16.1 betas.
