I have a working demo at:

• https://github.com/dankogai/swift-jsdemo

And here is the part that implements block registration:

typealias ID = AnyObject!
extension JSContext {
    func fetch(key:NSString)->JSValue {
        return getJSVinJSC(self, key)
    }
    func store(key:NSString, _ val:ID) {
        setJSVinJSC(self, key, val)
    }
    func store(key:NSString, _ blk:()->ID) {
        setB0JSVinJSC(self, key, blk)
    }
    func store(key:NSString, _ blk:(ID)->ID) {
        setB1JSVinJSC(self, key, blk)
    }
    func store(key:NSString, _ blk:(ID,ID)->ID) {
        setB2JSVinJSC(self, key, blk)
    }
}

You need a very small objc code and bridging header to make it work. See the repository for details.
