Bundle.main.url(forResource: "AppleIncRootCertificate", withExtension: "cer") == nil

Question

In order to set up Receipt-Validation in a Swift iOS app (using In-App-Purchase ), I am following this tutorial: https://www.raywenderlich.com/9257-in-app-purchases-receipt-validation-tutorial and reading here: Validating Apple Signed the Receipt .

Here is a problem I have at this point.

In the code I have this:

Bundle.main.url(forResource: "AppleIncRootCertificate", withExtension: "cer")

And when I check its value, it is nil. Since it is supposed to be used to extract further information, it shoud obviously not be nil. The question is: what could be wrong in the code or in some setting to make this nil?

This is my first time to implement Receipt-Validation, so it may well be that I am missing something basic.

Answer 1

I think you probably solved your issue, but this may be useful for someone else on how clearly solve the issue. So, if

Bundle.main.url(forResource: "AppleIncRootCertificate", withExtension: "cer")

gives you nil , you don't have this certificate. As suggested in comments above, go here and download needed certificate unde the Apple Root Certificates -> Apple Inc. Root Certificate.

Now you need to add downloaded certificate to your target. Move to Build Phases of your target, expand Copy Bundle Resources and press "+" button. Then select "Open Other..." and select certificate. Check the box "import if needed" or something like that and launch an app. Now you shouldn't get nil.
