Describe the bug
When following this guide to create a custom ViewController and then trying to use Swift in Objective-C, this error happens.

To reproduce
Steps to reproduce the behavior:

1. Create a new ionic project with this command ionic start SimpleSample tabs --type vue
2. Then open project folder in VS Code, add iOS Project then Build & Sync
3. Open in Xcode and follow guide to create a custom MyViewController.swift and set in Main.storyboard as Bridge View Controller, change its parent class to CAPBridgeViewController
4. Then create new Objective-C source files SampleOC.h & SampleOC.m under App, add #import "App-Swift.h" in SampleOC.m then compile and error occurs
5. If I delete this line #import "App-Swift.h" or change parent class back to UIViewController, error disappears

Expected behavior
Add #import "App-Swift.h" in SampleOC.m then compile and no error occurs and call swift code from oc has no error.
