Consuming third-party libraries written in Swift

[jasssonpet]

For example: https://github.com/danielgindi/ios-charts

• Respect objc_runtime_name attribute
• Require for native APIs #95 - Swift supports namespaces, so there could be collisions
• Swift modules use mangled name which is different than the klassName so get the name from the metadata #274 - Support Swift name mangling

The following would enable support for all Swift exposed code
#274
NativeScript/ios-metadata-generator#15

Those would enable support for all Swift exposed code. According to Apple's documentation

A Swift class or protocol must be marked with the @objc attribute to be accessible and usable in Objective-C. This attribute tells the compiler that this piece of Swift code can be accessed from Objective-C. If your Swift class is a descendant of an Objective-C class, the compiler automatically adds the @objc attribute for you.

All others would not be available in our runtime.

Hi is it possible now to use Swift based pods? If so what is the step required ? Or just
Like regular pods?

Thanks

@x4080: Yes, you can consume a Swift-based pod just like a regular pod, provided the Swift code is exposed to Objective-C, like in the ios-charts pod.

Thanks

@fealebenpae Maybe we should mention this in the docs?

[jasssonpet]

The Swift limitation isn't limited to CocoaPods only, so maybe we should add it to a broader article about using third-party native code.

I am having a heck of a time trying to get this to load https://cocoapods.org/?q=TTG ...same deal, because it was generated in swift?

Where does one see if the code is exposed to OBJC?

[fealebenpae]

@sitefinitysteve: it is exposed to Objective-C - the TTGSnackbar class derives from UIView which is an Objective-C class and all Swift classes that derive from an Objective-C class are implicitly exposed. I've just confirmed that the metadata generator sees the class in the pod. You can do the same by following the instructions in this blog post: http://jasssonpet.github.io/generating-typescript-declarations-in-nativescript-for-javascript-coffeescript-code-completion.
