I am trying to build the iOS App on a real device but unfortunately I get hit by a 

dsymutil exited with code 1

Things I did:

  • I did search google but it says my Harddisk is full which is not the case.

  • I did try to clean and build multiple times - No success

  • I did try to reinstall CommandTools by using command xcode-select --install - No Success

  • I did remove the CommandTools and then did the reinstall - No Success

Just an FYI

  • I am using Xcode 11.4 Beta 2

  • I am logged in with my Apple Account on the Xcode

What my cause this issue?

Any other info you would like to ask do ask.

Thanks

  • There will probably be a bit more to such errors, can you show us the part of the build log where it fails? – Cheesebaron Feb 28 '20 at 14:12
  • Hi , does it works before ? And better not using beta version of xcode to test xamarin , there will be conflict in somewhere we not knowing . – Junior Jiang Mar 02 '20 at 05:16
  • I am using the beta version because the current release is 11.3.1 (Stable) but it doesn't support my iOS device which is 13.4 only the 11.4.2 beta supports it – Noob Coder Mar 02 '20 at 08:28
  • @Cheesebaron I have added Build Logs do check – Noob Coder Mar 02 '20 at 08:31
  • @NoobCoder Does it works in previous version , not suggesting testing with beta version . By the way , the error shows that `Unable to locate the block to delegate conversion method for the method CIS.iOS.AppDelegate.WillPresentNotification's parameter #3` methoth `WillPresentNotification` occur error , you can have a check that . – Junior Jiang Mar 03 '20 at 03:31
  • @JuniorJiang-MSFT nope. I did a hard reset now and its gone now. Reinstalled the whole OS and then reinstalled the Xcode and other tools its now working. But still no official solution found – Noob Coder Mar 03 '20 at 08:05
  • @NoobCoder Okey , whether the reinstalled OS is stable version ,right ? – Junior Jiang Mar 03 '20 at 08:25
  • @JuniorJiang-MSFT yes I reused the same dmg to reinstall the OS and Updated it like before. Kinda was pulling my hairs when this error came out. But now its gone so I am kinda relaxed – Noob Coder Mar 03 '20 at 10:16
  • @NoobCoder Got it , glad solved it . You can share this solution as an answer , other people will know it . – Junior Jiang Mar 04 '20 at 01:14
  • @JuniorJiang-MSFT I wouldn't call this a solution as I had to Uninstall everything – Noob Coder Mar 04 '20 at 07:20

  • @NoobCoder Okey , I guess the problem should be the Beta version of Xcode as I said before . – Junior Jiang Mar 04 '20 at 07:27
  • Find the answer in the below link, it works perfectly. https://stackoverflow.com/a/71759982/5043390 – Sivabalaa Jothibose Jun 02 '22 at 10:03

Here is the solution:

I went inside Xcode.

Preferences>Locations> Command Line Tools. Mine was on 13.2, needed to upgrade to 13.3 (Thought I already had but it must not have done it automatically)

    Thanks for this. When I went to Preferences>Locations> Command Line Tools in Xcode I got nothing.... the field was blank. I've added the right version and the error has been fixed. – Syl.H Jul 05 '22 at 06:07

Check for Xamarin.ios version, mine was incompatible with visual studio Mac

i changed it when I was debuging on a windows machine connected to a Mac and VS windows said if I wanted to download compatible version, clicked yes and it downloaded and installed on the Mac computer

After that, I wasn't unable to debug on physical devices

suddenly after almost giving up a "Xamarin.ios update is ready, click to install update" came on VS Mac

after that I got no errors

This discussion was very helpful. I also had to make sure my VS for Mac updates were all installed. Once they were, everything needed to align just right, it worked.

We have resolved this issue now. All we did is we just updated Xamarin.iOS, Mono Framework MDK and Visual Studio for Mac to the latest versions.

Just go to Visual Studio → Check for Updates and then update all.

The error is kind of a hair puller.

So here is how I did it

First I uninstalled ALL of the XCODE

I followed this article on stackoverflow

After that I downloaded the Xcode from Apple from this article

Also download the CommandLine tools for that version. After that it worked and now I am not getting any error.

Remember this that CommandLine Tool versions should also match. 11.4.2 will not work with 11.3.1. I tested this and wasted alot of time.
