Yesterday i update my Xcode 11.1 to 11.2 After update the Xcode 11.2 and simulators extremely slow. Sometime simulator stuck on application Splash screen. Can anyone now what problem with new Xcode 11.2 and how to solve it?
I found this online. Are you using an application like BetterTouchTool? This seems to be a common problem.
I have found a solution for me. I am using BetterTouchTool and it was the one that was freezing the iOS simulator. So I disabled BetterTouchTool just for the simulator and now it is working normally.

When running applications on the simulator with Xcode 9, I regularly experience a handful of visual glitches, which include red device identifier labels and content that duplicates itself and leaves pixel mess after it moves. I did not have these issues with Xcode 8.
These occur regardless of the OS of the simulator, I replicated the issue with iOS 11 and 10.
This might be unrelated, but I use a legacy version of iClipboard (6.0.0) and a similar glitch persists inside the search bar sometimes.
What causes these glitches and what can I do to fix them?
Re-installing macOS High Sierra latest version (10.13.4 (17E202)) will solve this issue, i had similar issue with my Mac-book Pro.
Please be sure you are hard formatting and then re-installing the fresh OS.
Try switching to the last Xcode. Xcode 11.5.0 is the latest current stable version.
Yestarday everything was working fine today come and whenever i try to start application with simulator there is a window saying : Cant boot Simulator.
Sad thing is now that new xcode needs simulators to display it bugs also my storyboards and nibs. tried Xcode 8.0 Simulator broken the accepted answer here still same bug... plz help :)
I'm experiencing a very strange simulator issue with Xcode Version 8.0 (8A218a).
The simulator starts fine when launching in portrait, however if I rotate to landscape it displays weird. Consequently, any Xcode projects that I run also face the same issue.
Any idea how to fix this?
I've tried resetting the simulator contents & settings from the simulator menus, restarting the simulator etc. but to no avail.
EDIT: Restarted Mac, no change :(
This is a known issue with Xcode 8.0. The issue is addressed in Xcode 8.1. You can work around the problem by turning off "Optimize Rendering for Window Scale" from the Debug menu.
Solved by reinstalling Xcode 8.0
I just updated to xcode 7.0 and now my app is hanging at the splash screen.
I'm using a Google Maps Pod.
At first a clean & build caused a build fail stating that the Enable bitcode needed to be switched off.
I did that. My app now builds, however when I install it to the simulator or iPad it hangs on the splash screen.
There are no issue flags being displayed and the app appears to just hang forever until forced closed.
Everything was working fine until this xcode 7.0 update. Any ideas?
A previous post xcode 7 issues
stated that there are some problems with content in the view controller when compiled with 7.0. The solution was to completely reassemble the views piece by piece until it starts working. This is not a practical response because of time constraints and financial aspects at work. I uninstalled xcode 7.0 and then went to the Apple developer archives and reinstalled xcode 6.4.
The app now runs correctly. Hopefully this will get sorted out by 7.1.
Everything was working perfectly when debugging my keyboard on Xcode 6.2 running iOS 8.2. After updating to Xcode 6.3 and iOS 8.3, I seem to be having difficulty getting the debugger to work. Has anyone experience similar problems? I've tried cleaning my build, uninstalling/installing my app, but nothing seems to work.
What happens is I build and run, and when I switch between keyboards to get to mine it just never pops up, instead it jumps to the default one. Upon ending the task, and doing it again it works perfectly, just not when I'm attempting to debug.
Some of the information from this answer is a bit outdated, but it was useful to me. I am still convinced that extension debugging on devices is 90% broken with XCode 6.3.2 and iOS 8.3. I've been debugging successfully from the simulator, though, and occasionally I'll get the device process to attach correctly from within XCode, but more often than not it just quits on me.
