Running Ionic 3 app on iPhone throws error: 2 duplicate symbols for architecture arm64

Question

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:

Ld /Users/man         


        

Answer 1

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 cordova-ios@4.4.0
• After that we should add platform with ionic cordova platform add ios@4.4.0
• The last one, run ionic cordova build ios, that open with xcode and build with your settings.

Answer 2

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

Answer 3

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

Answer 4

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.
