Hey, sorry for the random comment but did you get GA to work with Swift?
I've added all the header files for GA to my bridging file and I can instantiate GAI objects from my AppDelegate without a problem (also added the required frameworks to the project).
Now when I try to go let tracker = GAI.sharedInstance().defaultTracker in any of my view controllers I get Use of unresolved identifier 'GAI'.
You wouldn't have an idea of what could be going on here by any chance?
Thanks so much!

swift 2:

extension UIViewController {
    func setScreeName(name: String) {
        self.title = name
        self.sendScreenView()
    }

    func sendScreenView() {
        let tracker = GAI.sharedInstance().defaultTracker
        tracker.set(kGAIScreenName, value: self.title)
        let builder = GAIDictionaryBuilder.createScreenView()
        tracker.send(builder.build() as [NSObject : AnyObject])
    }

    func trackEvent(category: String, action: String, label: String, value: NSNumber?) {
        let tracker = GAI.sharedInstance().defaultTracker
        let trackDictionary = GAIDictionaryBuilder.createEventWithCategory(category, action: action, label: label, value: value)
        tracker.send(trackDictionary.build() as [NSObject : AnyObject])
    }
}

There's a typo in the first function:

I believe func setScreeName should be func setScreenName

screeName becomes screenName

swift 3 & GA 3.17.0:

extension UIViewController {
    func setScreenName(name: String) {
        self.title = name
        self.sendScreenView()
    }

    func sendScreenView() {
        weak var tracker = GAI.sharedInstance().defaultTracker
        tracker!.set(kGAIScreenName, value: self.title)
        tracker!.send(GAIDictionaryBuilder.createScreenView()?.build() as [NSObject : AnyObject]!)
    }

    func trackEvent(category: String, action: String, label: String, value: NSNumber?) {
        let tracker = GAI.sharedInstance().defaultTracker
        let trackDictionary = GAIDictionaryBuilder.createEvent(withCategory: category, action: action, label: label, value: value)
        tracker?.send(trackDictionary?.build() as [NSObject : AnyObject]!)
    }
}
