I am opening .xcworkspace of my Ionic 3 project and trying to run it on my device but I suddenly get the following error in Xcode:

I don't understand what is duplicated... any help would be really appreciated.

Possible duplicate of Duplicate Symbols for Architecture arm64 – Dolphin

To solve the problem please have a look over this blog post from Cordova iOS 4.5. http://cordova.apache.org/announcements/2017/09/08/ios-release.html

You need to remove plugin "cordova-plugin-console" that is installed by default when generating a new Ionic project. Now this is in core part of cordova for iOS.

in case anyone's wondering how to remove plugin : cordova plugin remove FOLDER_PLUGIN_NAME – Amazonite

Since duplicate symbols are there, just removed "-ObjC" from both Targets and Project:

Build Settings -> Linking -> Other linker flags.

also try to remove any unwanted libraries from

Targets -> Build Phases -> Link Binary with Libraries

Thank you so much for this answer. I tried everything so far! Nothing worked except for this. Thanks again – Starve
This answer is working if you are using old cordova versions.Many thanks – Assuan
As an Obj-C developer your process was my gut-sense but since we are using ionic for this project it is logically correct process was to remove the duplicate via cordova. – Antilepton

The problem here is cordova-ios@latest.

And we could fixed this issues with:

  • Uninstall cordova-ios first, with npm uninstall cordova-ios
  • Install cordova-ios with npm install [email protected]
  • After that we should add platform with ionic cordova platform add [email protected]
  • The last one, run ionic cordova build ios, that open with xcode and build with your settings.

This worked. I was at [email protected] to 4.4.0 and it worked. – Barfuss

Since cordova IOS 4.5 they are including cordova-plugin-console, which results in the plugin being duplicated.
To fix just run: 

cordova plugin rm cordova-plugin-console
