Swiftish syntax?

[lexrus]

let tweak = FBTweak(identifier: "com.tweaks.example.advanced")
tweak.name = "Advanced settings"
tweak.defaultValue = false

let collection = FBTweakCollection(name: "Enable");
collection.addTweak(tweak)

let category = FBTweakCategory(name: "Settings")
category.addTweakCollection(collection);

let store = FBTweakStore.sharedInstance()
store.addTweakCategory(category)

tweak.addObserver(self)

// ...
func tweakDidChange(tweak: FBTweak!)
{
    self.advancedSettingsEnabled = tweak.currentValue as Bool;
}

Compared to:

FBTweakStore.sharedInstance()
  + FBTweakCategory(name: "Settings")
  + FBTweakCollection(name: "Enabled")
  + FBTweak<Bool>("com.fb.example", "Advanced settings", false) {
      tweak in
      self.advancedSettingsEnabled = tweak.currentValue
    }

And the rhs should support Array as well:

let collection = FBTweakCollection(name: "Enabled")
    + [
        FBTweak<Bool>("com.fb.example", "Advanced settings", false) {
          tweak in
          self.advancedSettingsEnabled = tweak.currentValue
        },
        // Another Tweak
      ]

I like that syntax!

The main barrier to Tweaks in Swift is that they aren't loaded at load time — the code has to run to initialize the tweak. Without a workaround for that, it's hard to make it nearly as practical as in Objective-C, since you'll often end up with duplicate tweaks (if you create them within an object) or a lot of boilerplate code to store static instances of them.

I haven't come up with a good way to work around that, but I'm still looking. If one is found, I think that will be a good impetus to make the rest of Tweaks work well in Swift too.

Some time ago I came up with this implement for a Swift tweak syntax.

Still there is the fact that it needs to run to be loaded, but it doesn't result in duplicates.
