importance of Bundle Seed ID during Create App ID? (Apple Provisioning Portal)

I am unsure about the importance of the Bundle Seed ID when creating a new App ID in the Apple Provisioning portal.

What should I consider when selecting a Seed ID?

When do I need to use an existin开发者_运维技巧g Seed ID?

On the iOS provisioning portal I found when creating a new app id you can select an existing Bundle Seed ID for your new app. I’m wondering if we should use the same AppID prefix between the free and paid versions and if so, why? I’d like to know the advantages and disadvantages.

Thanks in advance...

Example App ID: ABCDE12345.com.foocompany.*

ABCDE12345 is the Bundle Seed ID (generated by Apple).

com.foocompany.* is the Bundle Identifier of the App ID and the Bundle Identifier in your Xcode project must start with ‘com.foocompany.’ and the asterisk can be replaced with a string of your choosing,

So, for your answer: The Bundle Seed ID is generated by Apple, so you don't have to worry about that. It gets created automatically.

Take a look on information about Wildcard app ID's. It makes it possible to get more apps on the same license!
