解决方案

发生在更新您的Xcode，但您使用的任何第三方工具可能不会更新与此架构 armv64 。

点击您的项目中的 Targets ，然后点击 BuildSettings 。

查找有效架构

只需双击，从中删除 armv64 。

确保只有armv7和 armv7s 。

如果这不工作，那么尝试删除 armv7s 。

请检查所有框架是否正确链接并参考。尝试删除并再次添加第三方工具的框架。

请检查所有框架是否正确引用。

在我的例子中， >

清理并构建项目。

希望它能帮助你。

I have updated my XCode to 6.0.1 Before this update, I was able to build my project in both simulator and in my device. But now, it is giving me Apple Mach-O Linker Error

I surfed a lot. I have deleted the DerivedData folder. Still having the Problem.

I am building a Phonegap App. Please help me.

解决方案

This kind of problems generally occur while updating your Xcode but any third party tool you are using may not be updated with this architecture armv64.

So Click on your Project Navigator from XCode.

Click On Targets from your Project and click on BuildSettings from it.

Find Valid Architectures in it.

Just double click on that and remove armv64 from that.

Make sure there is armv7 and armv7s only.

If this does not work then try to remove armv7s also.

Please check all your frameworks are linked properly and referenced. Try to remove and add again the frameworks for that third party tool.

Please check all the frameworks are properly referenced.

In my case this worked for me.

Clean and build your project. It should work fine now.

Hope it helps you.
