Deep link is received twice in iOS in Ionic 2

Hi, We are using Branch with the latest version of Ionic 2 (2.2.0). We have found that deep link is received twice in iOS on cold start.

How to reproduce the issue:

1. Install latest Ionic CLI 2.2.1.
2. Install Cordova 6.5.0.
3. Create a brand new project with: ionic start --v2 myApp tabs.
4. Install branch plugin.
5. Follow plugin configuration and setup.
6. Build and run in an iPhone 6 with iOS 10.2.
7. Kill the app.
8. Generate a branch link and click on it.
9. The app starts and the link is received twice.

The expected behavior is to receive only one time the deep link.

We can provide a sample project already created and a link, too.

Regards and thanks in advance, Bea

Hello @nickpetrov,

Ionic 1 & 2 are odd as their own device event handling gets duplicated on iOS resume. This behavior is the opposite behavior from Cordova, PhoneGap, and Ionic 3.

This hotfix I pushed originally was meant to stop the double opens which were happening (causing analytical discrepancies in the Brach Dashboard).

I’ve looked into this issue again and was unable to reproduce the error. Please make sure you have updated your Branch SDK. Furthermore, you want to make sure you are using branch.initSession() to read you deep link data and not the depreciated DeepLinkHandler() method.

Thanks,

@ravi-pandit14, Make sure you have branch.initSession() in both deviceready and resume. https://github.com/BranchMetrics/cordova-ionic-phonegap-branch-deep-linking#initialize-branch

Additionally, make sure you follow the flow of a user. Deep link click -> app store -> install -> open -> read branch.initSession().

Lastly, branch.initSession() will not be called if there is a mismatch between deep link click and app open. The best way to test your configuration is by following this guide https://github.com/BranchMetrics/cordova-ionic-phonegap-branch-deep-linking#test-deep-link-ios
