[Tracking] iOS App Extensions

先阅读此 tracking issue 的“Overview”和“Known issues”部分。它没有指定实现文件、测试或单个范围明确的变更；请利用其中列出的扩展行为，以及签名、framework 和多扩展方面尚未解决的限制，来定义一个具体的后续 issue。完成的标准是有一项单独确定范围的改进，并进行明确的验证。

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
