Just came across this on apple Keychain Services Concepts
Note: On iPhone, Keychain rights depend on the provisioning profile used to sign your application. Be sure to consistently use the same provisioning profile across different versions of your application.
I also know that provisioning profiles can change for many reasons, including adding a new functionality like push notification, adding watch support, or even adding a new team member.
Now am I correct to assume that whenever above changes occur, new versions of my app will no longer be able to access keychain items that were created with previous versions?
Thanks!
I don't think your assumption is right. The Keychain Acces only depends on the bundle identifier of your application and the profile which was first used to create the app. If it would depend of your code-provisioning profiles changes, indeed what you said would be correct, but if so, the bussinesses and the enterprises would be totally unable to develop updates for their applications, which would have also included the old info stored in the Keychain. That's because in a bussiness, people come and leave often!

You can add a team member, configure a push notification services and so on, as long as the provisioning profile stays the same.
Note: If you change the provisioning profile just to add a team member, yes, your assumption is right, but it just isn't the best way of doing this. Rather, I recommend reading this tutorial (on how to add a team member to a provisioning profile).
