[Tracking] iOS App Extensions

Overview

iOS App Extensions feature enables adding extension via NativeScript plugins or with adding extensions folder inside App_Resources/iOS/.

The extension should be created and developed inside Xcode. Once the user is happy with the result, the folder containing the extension should be copied inside App_Resources/iOS/extensions. The an extension.json should be added. This file describes the SDK frameworks used in the extension and the assetcatalogCompilerAppiconName. For example:

{
    "frameworks": ["NotificationCenter.framework"],
    "assetcatalogCompilerAppiconName": "AppIconExtension"
}  

In the example above you should have an .xcassets catalog with AppIconExtension.appiconset inside the extension folder.

Each folder inside App_Resources/iOS/extensions is considered a separate extension and the folder name is considered the extension name.

Known issues

• The extensions inside NativeScript application support only Automatic code signing. Any provision configuration inside App_Resources/iOS/build.xcconfig will be ignored. And the application build will most probably fail.
• Currently including multiple extensions using the same SDK framework is not supported.
• Local frameworks (not SDK ones) will not be included in the build of the extension

Discussion

Please, don't report problems here. Instead, open a new issue and link it to this one.
Let's use this discussion for suggestions and improvement ideas. We would love to hear from you!

Start by reading the Overview and Known issues sections of this tracking issue. It does not name implementation files, tests, or a single scoped change; use the listed extension behavior and unresolved signing, framework, and multi-extension limitations to define a concrete follow-up issue. Done would require a separately scoped improvement with explicit validation.
