问题:

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.

回答1:

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 ;]

回答2:

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

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)

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
