I'm new to iOS coming from Android. I try to run simulator and open the Control Center on it. When I swipe from the bottom to up I see that it's empty. Any ideas what's going on with my simulator?
I tried at iPhoneX simulator and have the same.
Unfortunately the Simulator does not show a true Control Center. Yes, a blank screen appears, but no controls are available in there. Welcome to iOS ;]
The problem not in Xcode but in iOS 11 simulator
Solved
I download iOS 10 simulator and control-center work good in Xcode 9.3
Control Center is not available in iOS Simulator but if you are looking for notification center, you can get it by swiping top-down on iOS simulator. You can test local notifications on simulator
I needed to do this specifically to do a screen recording, but I realised you can't do it that way. So I found out about this way https://medium.com/@skounis/take-a-screenshot-or-record-video-with-ios-simulator-90c196e03b67 for anyone looking to do the same.
xcrun simctl io booted recordVideo <filename>.<extension>
To stop recording, press Control-C in Terminal.
PS - for iPhone X emulator you need to swipe from the top right down (even though that doesn't get you what you want)
