Tell us about the problem

In case the icons in <project dir>/app/App_Resources/iOS/Assets.xcassets/AppIcon.appiconset are not generated by Xcode, but for external tool, like https://apetools.webprofusion.com the tns resources generate icons command fails

Which platform(s) does your issue occur on?

No matter

Please provide the following version numbers that your issue occurs with:

• CLI: 4.1.0
• Cross-platform modules: Not applicable
• Runtime(s): Not applicable
• Plugin(s): Not applicable

Please tell us how to recreate the issue in as much detail as possible.

1. $ tns create myApp
2. $ cd myApp
3. Generate some icons in https://apetools.webprofusion.com - this will produce a .zip file. Get the iOS/AppIcon.appiconset folder from it and replace the myApp/app/App_Resources/iOS/Assets.xcassets/AppIcon.appiconset content.
4. Run $ tns resources generate icons <path to some icon>
   Instead of generating icons, the command will fail with error: Error: Invalid settings specified for the resizer.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

No.
