I'm working on a project for iOS and I'm doing the programming with Visual Studios and it connects to a mac server using Xamarin. I recently tried to add more views to the storyboard and an additional class. When I tried to build the code, I received this error. http://pastebin.com/Ub5s89aa This is what the output from the console. http://pastebin.com/fhWDy2cJ
I don't know what this error means and when I tried to look up any part of the error, nothing helped. I cleaned my builded and tried to rebuild, and I also closed Visual Studios and reopen it to see if that help, but it didn't. Has anyone else had this problem before?
Restarting the CoreSimulatorService solved the issue on my machine.
sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
I had the same problem after I upgrade my Xcode to version 10.3.
I just restart my Mac and problem solved!
Hope this would work with you too :)
Mine happened when updating to Xcode 10.3
X-code helper didn't get the permission to control the computer.
This is what i did to solve the problem
System Preference > Security&Privacy > privacy tab > accessibility
give permission for 'Xcode Helper'
Restart X-code and kill all simulators like @riik stated
sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
This issue is with xcode update 10.3 and mixpannel is gives this as build error
Steps to fix.
Open terminal and paste this
sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService
Clean Xcode and build. Thats all
After having a google I found a similar question here and here, summary of the some of the answers in that question:
- Make sure you are running the latest version of Xcode and you dont have a beta installed.
- Close Xcode and then opened up Activity Monitor. Terminate any
Ibtool processes running and restart Xcode.
- Delete any custom color pickers you have installed in for Xcode, close the Xcode and relaunch
- Try recreating any nibs you may have changed.
summary from the Xamarin Forums link:
Uninstall Xamarin studio, Xcode
Delete /Libraries/Developer and
~/Libraries/Developer folders
Reboot
Reinstall Xcode, Xamarin studio
If none of these work could you check in the Console.app for any errors when building.
Hope this helps.
I fixed same issue by restart mac and rebuild project. CMD + B!
None of these other solutions worked for me, unfortunately.
After hours of digging, I discovered I had to reset the read/write permissions in my home folder.
