Just wanted to confirm that I am experiencing this copy/paste problem as well after updating to 26.4. I've tried disabling and enabling the pasteboard sync, restarting the simulator, reinstalling 26.4 iOS version, restarting my MacBook. None of it works. I also get the following output for the command suggested by @DTS Engineer xcrun simctl spawn booted launchctl kickstart -k system/com.apple.pboard Could not find service "com.apple.pboard" in domain for system I hope this will get a high priority because this makes my work a lot more tedious.
