AppsFlyer enables you to measure app uninstalls. To handle notifications it requires to modify your AppDelegate.m. Use didRegisterForRemoteNotificationsWithDeviceToken to register to the uninstall feature.

Example:

@import AppsFlyerLib;

...

- (void)application:(UIApplication ​*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *​)deviceToken {
// notify AppsFlyerLib
 [[AppsFlyerLib shared] registerUninstall:deviceToken];
}

In-app purchase validation

Receipt validation is a secure mechanism whereby the payment platform (e.g. Apple or Google) validates that an in-app purchase indeed occurred as reported.

appsFlyer.setUseReceiptValidationSandbox(true);

successC	function	success callback (generated link)
errorC	function	error callback

Example:

let info = {
        publicKey: 'key',
        currency: 'biz',
        signature: 'sig',
        purchaseData: 'data',
        price: '123',
