Can I exchange files / data through application groups, but in different applications of developer accounts?

Question

As far as I know, I know that we can share files between two applications through App Groups developed by the same developer account / certificate.

But here is my question: can I do the same Sharing file between different apps through App Groups with different applications developed by different developer accounts that are processed by mine?

Answer 1

The answer is no.

If you create a training profile with the my.app.group application my.app.group and extract rights from it, you will see that the group is referred to as XXXXXXX.my.app.group , where XXXXXXX is your developer identifier, so the group will be on another account YYYYYYY.my.app.group , and it will be perceived as another group by any device.

Additional Information: Application Identifier, Application Groups

Answer 2

Apple recently launched Files, an iOS 11 app that can help do the job.

These are just a few steps for exchanging / exchanging data between two different applications from different developer accounts, but it may be work.
