this will help This is actually a known bug in the iOS 5.1 Simulator. I have filed radars with Apple to get it fixed, but have basically been ignored. They responded with "does it work in the iOS 6 beta simulator". Which it does. I got the same issue where it only triggers one location event for region monitoring. In or out, but no more than one.
Dragging multiple images to iOS Simulator broken in Xcode 7.x ? (7.2)
This might help you This is an incompatibility with BetterTouchTool. Quitting BetterTouchTool is not sufficient. BetterTouchTool's accessibility privileges must also be revoked in Security & Privacy. Upgrading to BetterTouchTool 1.5.2, whose version notes allude to fixing a simulator problem, does not appear to have fixed this issue.
I wish did fix the issue. What is most likely to be the case is that your XCode installation is corrupt. The best thing to do is to delete Xcode entirely and also these directories and files: ~/Library/Caches/com.apple.dt.* ~/Library/Caches/xctest ~/Library/Containers/com.apple.dt.* ~/Library/Developer ~/Library/MobileDevice ~/Library/Preferences/com.apple.dt.* ~/Library/SavedState/com.apple.dt.*
I wish this help you Well that was one of the stranger bugs I've come across. For some reason, it appears 'tap to click' on my trackpad wasn't activating the switch. I tried 'press to click' and a USB mouse and both worked. It only occurs with switches on the simulator. Everything else activates, buttons, cells, etc.
Xcode 9.2 Simulator Debugging Broken; Could not attach to process id
wish of those help It turns out our security software was blocking the debugger. Running sudo sysdiagnose helped me find a log entry showing that it was being blocked. The software is Cb Defense (Carbon Black Defense). Apparently the only workaround is for your security team to whitelist by a hash, and that hash could change in the future.
