Hi Folks i intgrated the AppDelegate Extension to Our Kony Studio app to get some AppDelegate functionality . I followed the following link tutorial.

https://docs.kony.com/konylibrary/visualizer/viz_widget_prog_guide/Content/PlatformSpecificCapabilities.htm

It is working fine when i change C++ Standard Library" key to "libstdc++ (GNU C++ standard library)" value.

But when i had it run on MacOs 10.14 and Kony Studio it shows the "error "Lexical or Preprocessor Issue, 'iostream' file not found dummy.cpp." How can I avoid this issue when I switch to linstdc++ ?""

This issue might come when you are using the Xcode 10 non compatible plugin. Can you please confirm your Visualizer version along with the plugin screenshot.

6.5 is a EOL version of Kony. This version doesn't have compatibility for iOS13 and Xcode11. Please check the below link for more details

@Twvcey Rvndvll​ yes i have been using macOS 10.14 series and Xcode 10.1. So what you suggest for that? Please kindly tell.

@Rvj Whitvkew​

You have to upgrade your Project to 7.3 or 8.x version to get the compatible version of iOS13 and Xcode 11.

@Twvcey Rvndvll​ i understand .. Thanks for reply but as i said i am using Xcode 10.1 right now. It doesnt has iOS 13 sdk by default ... So little confused about you mentioningabout iOS 13 and Xcode 11. And one more thing to add to this... iOSStream error is not shown when i use the appdelegate extension on another System with 10.14.6 OS version and same xcode 10.1 and it works fine there. So what do you suggest in this? Is there a need to migrate the project to Visulaizer Version and then start using the Appdelegate Extension? Is that the best suggestion from your side. please kindly suggest.?

@Rvj Whitvkew​

Apologies for the confusion. As per the support plan the 6.5 version doesn't have any kind of support. For any kind of support or bug fix, you need to upgrade your application to the latest version.

Even if it work in one MAC and you generate the IPA with Xcode10 and when you submit to Apple it will get rejected. The best approach is to upgrade your application to the latest version of Kony Visualizer.
