Build failed with xcode 10 beta

Question

I created a new project on Xcode beta and built it, It gives me the below build error.

Encountered an error communication with IBAgent-iOS on launchscreen.storyboard.

The same storyboard error that I am getting when I try to build any sample projects built on Xcode 10 beta.

Has anyone come across the same issue with Xcode 10 beta IDE?

I face the same issue with Xcode 10.1... issue resolved by just clean the build folder using Command+Shift+K

I hope this will work for you.

I'm on Xcode 13 and still get the issue sometimes. No help with cleaning the build folder or removing DerivedData.

However, this usually saves my life ^^

sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService

I had the same error.
I renamed Xcode from Xcode-beta to Xcode and it worked for me.

It worked for me too..!! I renamed xcode 9.4.1 (version current stable) to Xcode_9.4.1 and v10.0 beta to Xcode.!! – myCmyL Jul 09 '18 at 07:55
This is applicable for the Xcode10 formal release too! It seemed irrelevant but it did work when I renamed the old xcode (9.4) to xcode9.4 and renamed xcode10 to xcode. – Wei WANG Sep 26 '18 at 05:37

I had the same problem with xcode 10 installed from the App Store and I tried removing the derived data, cleaning the build folder... nothing worked.

And then I just restarted my computer and it's working. I did not rename anything. It must be some glitch in the memory which is solved after restarting the system.

You need to remove the Targets from that xib, compile and add them back to your xib and compile. It works!

I renamed the

Xcode to Xcode10 (from finder > Applications),

and then cleaned the build folder

(Xcode > Product > Clean Build Folder).

It worked for me.

I'm using Xcode 11 but still, encounter this problem, I've tried to clean the project and rebuild it but it still won't work. The only solution I found it work is to uninstall Xcode and download the new one from App Store, this work fine with me and I can use it normally now. I hope this works for you guys too. Cheer.

If you are getting this issue, then I think it is bug of an Xcode 10. The only fix is uninstall your Xcode 10 , and reinstall it again . It will definitely work. This worked for me. Thanks.
