[question] How to use platform specific code in libs?

Comece por libs/nativescript-utils/src/index.ts e pelos arquivos específicos da plataforma e, em seguida, compare os arquivos tsconfig.json e tsconfig.lib.json da biblioteca com o tsconfig.app.json dos apps. Reproduza o erro de arquivos ausentes na compilação do TypeScript e rastreie qual configuração controla a inclusão dos arquivos da biblioteca. Está concluído quando as implementações .ios.ts e .android.ts compilarem ao serem importadas da biblioteca.

It's me again :)

This time it's a question on how to do platform specific code in the libs. Here's my current issue:

I have these files under libs/nativescript-utils:

• src/lib/nativescript-utils.d.ts
  • export function nativescriptUtils(): string;
• src/lib/nativescript-utils.android.ts
• src/lib/nativescript-utils.ios.ts
• src/index.ts
  • export * from './lib/nativescript-utils';

Then I import the nativescriptUtils() in the app. When running the app I get this error:

ERROR in ../../libs/nativescript-utils/src/lib/nativescript-utils.ios.ts
Module build failed (from ../../node_modules/@ngtools/webpack/src/index.js):
Error: /Users/frank/git/private/nx-mobile-test/libs/nativescript-utils/src/lib/nativescript-utils.ios.ts is missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.

I did the same exercise under apps, d.ts + ios.ts + android.ts + index.ts -> same issue -> solved it by adding "**/*.ios.ts" to includes in tsconfig.app.json. But no matter what I do in the libs and tsconfig.json or tsconfig.lib.json, it's not being picked up.

Do you have any tips on how to fix this?
