How to implement Firebase Google Analytics in custom keyboard?

Question

I want to implement Firebase google analytics in my custom keyboard for button click event.

Anyone please tell me how I can do this in swift.

I'm voting to close this question as off-topic because this is normal as using Google Analytics. Nothing special in keyboard. — Zaid Pathan

@Zaid Pathan, Normal implementation having big trouble e.g crash [reason: 'Default app has already been configured.']. So that I have asked this question. Could you please help me if you know the solution as I have described my problem in below radugrinico's answer. — Sunil Targe

Can you try calling FIRApp.configure() twice where ever you're calling? It may fix the issue. Here is something similar : stackoverflow.com/questions/37910766/… — Zaid Pathan

Add firebase sdk and GoogleService-Info.plist file to keyboard extension target. Import firebase and configure it. FIRApp.configure() must be called only once per session:

import Firebase

class FirebaseConfigurator: NSObject {
static var onceToken: dispatch_once_t = 0

static func configure() {
    dispatch_once(&onceToken) {
        FIRApp.configure()
    }
}

and

FirebaseConfigurator.configure()
FIRAnalytics.logEventWithName("button click event", parameters: nil).

I have done the same, but problem is when I switch my custom keyboard to native iOS keyboard and again native to custom then FIRApp.configure() method calling again and throwing **error- [reason: 'Default app has already been configured.'] ** and app crash.

@SunilTarge, you need to make sure that FIRApp.configure() is called only once per session.

yes I understood but I don't know how to calculate new session of Extension keyboard. because it doesn't have AppDelegate class.

@SunilTarge, I edited the above code. I moved FIRApp.configure() into a singleton so it will be called only once even if you call FirebaseConfigurator.configure() multiple times.
