How to use Chartboost Analytics with swift?

I've imported Chartboost via headers and cannot get CBAnalytics from Chartboost.framework to call next function in Swift.

+ (void) trackInAppPurchaseEvent:(NSData *)transactionReceipt 
                         product:(SKProduct *)product;

I followed these instructions https://answers.chartboost.com/hc/en-us/articles/205606995 https://answers.chartboost.com/hc/en-us/articles/204639335-Post-Install-Analytics-Event-Level-Tracking-via-SDK#ios

Solution

  • I had a pre-existing Obj-C project, so I jury-rigged it to show this call in Swift.

    Here's the SDK header import I needed to add to my project's Bridging-Header.h file:

    #import <Chartboost/CBAnalytics.h>

    Here's my actual Swift call:

    //Swift
@objc func makeChartboostPIACall(myReceipt:NSData, myProduct:SKProduct) {
    CBAnalytics.trackInAppPurchaseEvent(myReceipt, product: myProduct)
}

    It SHOULD be that easy, but here's a little more detail on where those values I was passing in are coming from:

    In my case, I was passing in the values from my Obj-C code:

    //Obj-C
[mySwiftInstance makeChartboostPIACall:transaction.transactionReceipt myProduct:myProduct];

    I made that call after I had just confirmed that a payment transaction had successfully completed (SKPaymentTransactionStatePurchased). Thus, "transaction" is a SKPaymentTransaction object, and "myProduct" is the matching SKProduct of what had just been purchased.

    It's worth noting that transaction.transactionReceipt is deprecated as of iOS 7, and this is the recommended method to use going forward:

    //Obj-C
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
