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

要解决这个问题，请查看 Cordova iOS 4.5 的这篇博文。 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.

您需要删除生成新 Ionic 项目时默认安装的插件“cordova-plugin-console”。现在这是 iOS 版cordova 的核心部分。

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

由于存在重复符号，只需从目标和项目中删除“-ObjC”：

Build Settings -> Linking -> Other linker flags.

构建设置 -> 链接 -> 其他链接器标志。

also try to remove any unwanted libraries from

还尝试从中删除任何不需要的库

Targets -> Build Phases -> Link Binary with Libraries

目标 -> 构建阶段 -> 将二进制文件与库链接

The problem here is cordova-ios@latest.

这里的问题是cordova-ios@latest。

And we could fixed this issues with:

我们可以通过以下方式解决这个问题：

• 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.

• 首先卸载cordova-ios，使用 npm uninstall cordova-ios
• 安装cordova-ios npm install [email protected]
• 之后我们应该添加平台 ionic cordova platform add [email protected]
• 最后一个 run ionic cordova build ios，用 xcode 打开并用你的设置构建。

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

从cordova IOS 4.5开始，它们包含cordova-plugin-console，这会导致插件被复制。
要修复只需运行：

cordova plugin rm cordova-plugin-console
