Project unable to build when using native api in code-sharing project

Environment

• CLI: 6.3.3
• Cross-platform modules: 6.3.2
• Android Runtime:
• iOS Runtime: 6.3.0
• Plugin(s):

Describe the bug
Unable to build when using native api (iOS) in angular code sharing project. I have tried using multiple different ios specific functions and classes but I always get the same error. "Cannot find name ..."

When trying to access the same function in a regular project (non-code sharing) everything works as expected.

To Reproduce

1. Create a code-sharing project.
2. Install tns-platform-declarations (https://www.npmjs.com/package/tns-platform-declarations)
3. Write some code that interacts with the native api.
4. Build/Run

Expected behavior
The code-sharing project should build just like the regular one.

Sample project

Additional context
Console output:
ERROR in src/app/home/home.component.tns.ts:9:21 - error TS2304: Cannot find name 'UIVisualEffectView'.

9 public overlay: UIVisualEffectView;
~~~~~~~~~~~~~~~~~~
src/app/home/home.component.tns.ts:19:22 - error TS2304: Cannot find name 'UIApplication'.

19 const window = UIApplication.sharedApplication.keyWindow;

Start with the linked sample project and src/app/home/home.component.tns.ts, then reproduce the Angular code-sharing build after installing tns-platform-declarations. Trace why UIVisualEffectView and UIApplication are unavailable in the TypeScript build; done means the sample builds and the native API references resolve as they do in a regular project.
