Custom Dimensions in Swift - swift

Question

I have an Objective-C app that integrates with Google Analytics. Now, I'm trying to integrate an app written in Swift.
There's my Objective-C Code:
- (void) signInGoogleAnalytics {
id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
// You only need to set User ID on a tracker once. By setting it on the tracker, the ID will be
// sent with all subsequent hits.
[tracker set:kGAIUserId
value:self.txtStoreCode.text];
NSString *dimensionUsuarioLogado = [NSString stringWithFormat:#"%#", _txtEmployee.text];
NSString *dimensionLoja = [NSString stringWithFormat:#"%#", _txtStoreCode.text];
[tracker send:[[[GAIDictionaryBuilder createScreenView] set:dimensionUsuarioLogado
forKey:[GAIFields customDimensionForIndex:1]] build]];
[tracker send:[[[GAIDictionaryBuilder createScreenView] set:dimensionLoja
forKey:[GAIFields customDimensionForIndex:2]] build]];
}
and I'm trying in swift
func signInGoogleAnalytics() {
let tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIUserId, value: txtStore.text)
var dimensionUsuarioLogado = "\(txtUser.text)"
var dimensionLoja = "\(txtStore.text)"
tracker.send(GAIDictionaryBuilder.createScreenView().set(dimensionUsuarioLogado, forKey: GAIFields.customDimension(forIndex: 1)).build())
tracker.send(GAIDictionaryBuilder.createScreenView().set(dimensionLoja, forKey: GAIFields.customDimension(forIndex: 1)).build())
}
but I'm getting GAIFields has no member customDimension. Then, how should be the code in Swift?

Answer 1

It worked for me:
func signInGoogleAnalytics() {
let tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIUserId, value: txtStore.text)
let dimensionUsuarioLogado = "\(txtUser.text)"
let dimensionLoja = "\(txtStore.text)"
tracker.send(GAIDictionaryBuilder.createScreenView().set(dimensionUsuarioLogado, forKey: GAIFields.customDimensionForIndex(1)).build() as NSDictionary as [NSObject : AnyObject])
tracker.send(GAIDictionaryBuilder.createScreenView().set(dimensionLoja, forKey: GAIFields.customDimensionForIndex(2)).build() as NSDictionary as [NSObject : AnyObject])
}

I was tracking custom exception with custom dimension:
//MARK:- CUSTOM EXCEPTION TRACKING
func doTrackCustomExceptionWithGA(message:String, customDimensionValue:String, isFatal:Bool = false) {
guard let tracker = GAI.sharedInstance()?.defaultTracker else { return }
guard let exceptionBuilder = GAIDictionaryBuilder.createException(withDescription: message, withFatal: NSNumber(value: isFatal)) else { return }
if !customDimensionValue.isEmpty {
exceptionBuilder.set(customDimensionValue, forKey: GAIFields.customDimension(for: 15))
}
guard let build = exceptionBuilder.build() as? [AnyHashable : Any] else { return }
tracker.send(build)
// ADDING DUMMY EVENT TO TRACK PREVIOUS EVENT QUICKLY, AS GA EVENTS ARE TRACKED ON NEXT EVENT CALLS
// BELOW CODE IS OPTIONAL
let event = GAIDictionaryBuilder.createScreenView()
tracker.send(event?.build() as! [NSObject: Any])
}
