0.9.0

This release introduces support for catching JSError instances in Swift from throwing JavaScript functions. This is possible thanks to the new JSThrowingFunction and JSThrowingObject classes. The former can only be called with try, while the latter will expose all of its member functions as throwing. Use the new throws property on JSFunction to convert it to JSThrowingFunction, and the new throwing property on JSObject to convert it to JSThrowingObject.

0.8.0

This release introduces a few enhancements and deprecations. Namely, JSValueConstructible and JSValueConvertible were renamed to ConstructibleFromJSValue and ConvertibleToJSValue respectively. The old names are deprecated, and you should move away from using the old names in your code. Additionally, JavaScriptKit now requires the most recent 5.3 and development toolchains, but thanks to this it no longer uses unsafe flags, which prevented building other libraries depending on JavaScriptKit on other platforms.

The main user-visible enhancement is that now force casts are no longer required in client code. That is, we now allow this

let document = JSObject.global.document
let foundDivs = document.getElementsByTagName("div")

in addition to the previously available explicit style with force unwrapping:

let document = JSObject.global.document.object!
let foundDivs = document.getElementsByTagName!("div").object!

Note that the code in the first example is still dynamically typed. The Swift compiler won't warn you if you misspell names of properties or cast them to a wrong type. This feature is purely additive, and is added for convenience. You can still use force unwraps in your code interfacing with JavaScriptKit. If you're interested in a statically-typed DOM API, we recommend having a look at the DOMKit library, which is currently in development.

Lastly, JSError now conforms to the JSBridgedClass protocol, which makes it easier to integrate with idiomatic Swift code.
