I have the same problem. Xcode 26.2, MacOS 26.2. This happens at least on every iOS 26 simulator (26.0, 26.1, 26.2). In my case I use the US-PC keyboard distribution in MacOS but simulator keeps using another one. I tried to restart them, create new ones, restart the Mac, Xcode... I started noticing it after changing to Xcode 26 from the 16 and resetting the simulator. Before resetting it everything worked well

Same here. A Rosetta-related bug?
