Apple Mach-O Linker (ld) Error Group
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I am running: meteor run ios-device, and I am getting that in build-time error logs in XCode 8.3.2, running on macOS 10.12.4, and meteor version is: 1.2.1
Any help is more than welcome, I am completely lost at this.
Solved
Using XCode8, Toggle Build Settings -> ‘No Common Blocks’ , see what works.
Hitting this error now. What was the setting that worked for you?
Turns out I was working with the .xcodeproj file;
I, instead, needed to open the .xcworkspace.
The error went away after that
I just encountered this issue again. It was fixed last time by using the .xcworkspace but now nothing helps
“: Linker command failed with exit code 1 (use -v to see invocation)”
is there anything else I have to try?
Same thing as @fullhdpixel : the workspace workaround used to work some months ago, but now it fails systematically with the same Meteor project.
This issue is really urgent for me. I’ve got a broken IOS app since two weeks in the play store and I cannot release new update.
OK, I solved the problem on my app by recreating a blank meteor project, carefully copying all code, asset and db files into the new folder, then reinstalling Meteor and npm packages.
Before reinstalling any Cordova plugin, I tried to deploy a build to iOS : it worked without problem. Then I reinstalled all Cordova plugins one by one, and noticed Xcode started to raise the Apple Mach-O Linker error again right after installing a specific plugin : phonegap-plugin-push.
But this time, the workspace workaround mentioned by @themuffinman worked again and I could deploy my app to iPhone.
10 days later, the problem is back again. The very same app I mentioned in my previous post refuses to build.
Still same issue. Here’s what I tried:
Honestly, I’m giving up on development with Meteor/Cordova right now. My startup idea is not working out anyway, but for my next project I’ll go try react native

Adding
cordova-plugin-console@1.1.0
to .meteor/cordova-plugins file fixed the problem for me.
Wow it works! Thankss!!
Indeed, installing this plugin - or upgrading to Meteor 1.6 beta 5 - removes the error if the build is issued from the workspace.
One of my iOS developers is facing this type of error, I am going to provide @diaconutheodor solution, I hope that would be work!!
The same issue still exists in Meteor v1.6.1 
.The root cause for me is the phonegap-plugin-push. I have had to rollback its version from 2.2.2 to1.9.4 to continue …
Had this come up. It appears to be due to a duplicate symbol. I had two different cordova plugins targeting similar IOS functionality, both using the same symbol in their code. Turns out I didn’t need one of the plugins so I just removed that one and it would build.
