Can you update the integration and podspec?

Hey @pasevin

I've opened an internal ticket to keep track of this. I need to investigate what the major changes were here, since we rely on version 7.6, and the latest Flurry SDK is past 8.

For now, you can simply depend directly on the latest by pinning the Flurry iOS SDK in your podfile, since Cocoapods will respect the most up to date version.

Thanks!

It would be great if the integration could be upgraded to support Flurry SDK version 8. They introduced some fixes for iOS 11 with version 8.3.1.

[iothmane]

Any new update on this ? Thanks

[ladanazita]

@iothmane Sorry for the delay here. This hasn't been prioritized but I will update this in my free time as soon as I can. We are also happy to accept PR's :)

It looks like Flurry is up to version 9.0, with some method changes. Specifically the funtionality we need to update:

Initialization:

[Flurry setSessionContinueSeconds:[sessionContinueSeconds intValue]];

// deprecated for: 
FlurrySessionBuilder* builder= [[[FlurrySessionBuilder new]
                                              withSessionContinueSeconds:s]
                                             withAppVersion:appVersion];

Location management:

[Flurry setLatitude:latitude longitude:longitude horizontalAccuracy:horizontalAccuracy verticalAccuracy:verticalAccuracy];

// deprecated for  
CLLocationManager *locationManager = [[CLLocationManager alloc] init]; [locationManager startUpdatingLocation];
