Deprecated Xcode Build issue while sent version from Xcode version 8.3

Question

I have recently uploaded a build in AppStore(TestFlight) and got the following mail from AppStore,

Dear developer,

We have discovered one or more issues with your recent delivery for "MY APP". Your delivery was successful, but you may wish to correct the following issues in your next delivery:

Deprecated Xcode Build - Due to resolved app archives issues, we will be deprecating Xcode 8.3 on May 10, 2017, at which time app archives built with 8.3 will no longer be accepted by the App Store. Download Xcode 8.3.2 or newer, rebuild your app and resubmit.

After you’ve corrected the issues, you can use Xcode or Application Loader to upload a new binary to iTunes Connect.

Regards,

The App Store team

Will there be any problem on releasing the current build for review ?
Or
Do I want to download the latest Xcode version as mentioned in the mail and upload an another build ?

Answer 1

Will there be any problem on releasing the current build for review?

If you submit your app for review and will be reviewed successfully before the May 10, 2017, than you do not need to do anything with you current build.

Do I want to download the latest Xcode version as mentioned in the mail and upload an another build ?

You should be updating to the latest Xcode anyway, at least for the sake of having all the latest tools and API's available. If you would like to submit a new build after the May 10, 2017, you have to update Xcode, rebuild the app and submit a different binary for Apple to review.

Overall, i would recommend to update now, and submit a different build, because you will have to do it anyway in the near future, and your app will not be rejected because of the Deprecated Xcode Build issue for sure.

EDIT:
Xcode 8.3.2 is available in the App Store.
