+[NSString platformName]: unrecognized selector sent to class 0x204da8948 for iOS SDK

I have implemented PiwikPro sdk for iOS and try to send screen_view event.

Following is the code is set in AppDelegate.swift file

PiwikTracker.sharedInstance(siteID: {site_id}, baseURL: {BASE_URL})
        PiwikTracker.sharedInstance()?.isAnonymizationEnabled = true
        PiwikTracker.sharedInstance()?.isPrefixingEnabled = true

When i try to log the screen event using its new object PiwikTracker()

PiwikTracker().sendView(view: screen_name)

Nothing happens on “Debug Tracker”

And when i try to log using its sharedInstance()

PiwikTracker.sharedInstance()?.sendView(view: "screen_name")

the application crashes with follwing error

*** Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘+[NSString platformName]: unrecognized selector sent to class 0x204da8948’

libc++abi: terminating with uncaught exception of type NSException

Is there anything I am missing?

And btw the sendView is being called from a UIViewController’s viewDidLoad() and viewDidAppear() methods


PS: I have setup sdk using Pods and the version is PiwikPROSDK (1.2.3)

Hi @adeel-7peaks,

Thanks for all the details. We’ll look into this and get back to you in case we need more info.

Are you using the -ObjC linker flag?
