Compatibility with Swift

[FGoessler]

The new programming language Swift is awesome but unfortunately it doesn't seem to support things like defines.
So we would need an other approach to define the dependencies of our classes without maintaining a lots of factories/providers.

Any ideas yet?

Yeah, it isn't surprising that it doesn't support preprocessor statements. However, I've adapted Objection to other languages before. Fundamentally, Objection doesn't require preprocessors macros to work. motion-objection is an example of this.

What it comes down to is whether Swift has a nice declarative programming API to work with.

Hi guys. Do you have any updates from swift compatibility front? Will objection work with swift base project?

I've had some luck by defining a generic 'inject()' function which wraps some of the manual injection logic

public func inject<T:AnyObject>() -> T {
    return JSObjection.defaultInjector().getObject(T.self as AnyObject) as! T
}

This lets you inject dependencies into classes as follows:

class MyViewController: UIViewController {
    var network: MyNetwork = inject()
    var analytics: MyAnalytics = inject()
}

Although this is still a little experimental this has been working great for me so far.
