You could use com.radaee.pdf.PDFViewer as a bundle identifier only with RadaeePDfViewer demo, I suggest you to take a look at RadaeePDF-Cordova repository
where it's explained how to install the plugin via terminal in an empty iOS project. I also suggest you to check our knowledge base to activate demo license
With Cordova 8 you could have some permission errors, to prevent them take a look at
this knowledge base
The plugin works without any problems on the simulator, but I have problems running it on a real device, because the namespace com.radaee.pdf.PDFViewer is not included in my developers certificate. Of course, I cannot add it, because it is already used by your company.
Try to download, install and run the
iOS Demo App
by debugging usb with com.radaee.pdf.PDFViewer as bundle ID, it will work and it also work with Cordova plugin. You don't need to be bundle ID's owner to run the app in debug USB using XCode, you only need it if you have to upload the app to TestFight or iTunes Connect.
Attached is a screenshot of the error I get when compiling your sample project on iOS. I get the same message with a sample Cordova application I created to test your plugin. I think it has to do with your bundle ID, but I am not quite sure.
You probably installed RadaeePDF Demo from App Store, XCode displays this error in this situation, you should uninstall the app that comes from App Store and reinstall it using Run Command from XCode
