What is the current behavior?

Currently, support for native Objective-C source code is not implemented.

What is the new behavior?

Following changes allow plugin authors to include raw Objective-C source code (.m and .h files) to their plugins. CLI looks for folder named platforms/ios/src folder and creates a pbxGroup in the .pbxProject named after the plugin. Files and folders are added to project recursively (NativeScript/node-xcode#6) and same structure is kept. Root folder (platforms/ios/src) is added to HEADER_SEARCH_PATHS as the plugin author still has to provide a modulemap for the source code.

Implements NativeScript/ios-jsc#885.

name property doesn't seem to be used and might be removed.

Try making the paths inside the groups relative, because this might cause problems in the future.

Great work

@tdermendjiev where is the modulemap supposed to be? i cant get it to work right now inside a plugin. I want to add a NSDate category

This is what i have.
The content of the modulemap is:

framework module BackgroundGPS {
  umbrella header "BackgroundGPS.h"

  export *
  module * { export * }
}

[mbektchiev]

That should be the right place. Can you try the troubleshooting ideas listed here and see if anything will come up?

[farfromrefug]

@mbektchiev nice article! Did not find the reason of my issue there. But found it it a component i had already doing that. Just didn't remember it :s The reason was the extra "framework" word in the modulemap.
Thanks again @mbektchiev

[mbektchiev]

Seems legit -- a framework module should expect the structure of a .framework bundle: https://clang.llvm.org/docs/Modules.html#module-declaration.

Weren't there any hints about this in the stderr logs of metadata generator?

[farfromrefug]

@mbektchiev not that i saw. The file was 3Mo though so not easy to read. But searching for my module name BackgroundGPS did not give anything.
But dont worry the issue was more on my side. What could be added to the doc though would be a an example on how to add sources. Something with a basic hello word showing the directory structure and the content of the modulemap. I think this would be helpful to many plugin devs

[mbektchiev]

In fact, we have such an example. But maybe it should be more visible. https://github.com/NativeScript/plugin-ios-modulemap-sample

It's linked here: https://docs.nativescript.org/plugins/Use-Native-iOS-Libraries#static-frameworks but obviously not the place that one would look for it ...

[farfromrefug]

Yes would be best for it to be more visible.
And also it does not show how to do it witch custom .m/.h/.c files. It uses Pods. Would be good to add an example with custom sources.
For sure know i will keep an eye on your "docs" repo. Find it easier to navigate than the website.
