Native linking failed - for iOS API 7.1
posted

Hi,

Until January 2014 I developed with Xamarin.iOS against API version 6.1 and it was working without any issues.

Now I have to worker further on this project, so I updated Xcode and Xamarin frameworks because Apple forced me to use API 7.x. Unfortunately my existing code for IGGrid is not working anymore. I get this linking errors:

    When iOS 7 was released we released a Service Release to fix issues that arose the new OS.  The error messages you are seeing would lead me to believe that you have not applied an SR to your package to bring the framework files and DLLs up to date.  The following forum post has the steps needed to apply the SR

    I would also recommend removing the references from your project, cleaning your project, and then ensuring any instances of xCode or Xamarins IDE are closed during the installation process to ensure the IDEs are not holding onto the files during the install.
