“An App ID with bundle identifier X is not available. Please enter a different string” (Xcode 7.3)

Question

After updating to the latest build of Xcode 7.3 (7D175), every time I try to Export for adhoc distribution I get the above error. Everything was working fine up until the up

Answer 1

I just installed Xcode 7.2.1 and could successfully export AdHoc build with it. While Xcode 7.3 keeps on telling that there is something wrong with bundle identifier.

UPDATE:

Looks like changing the "Name" (not the ID) of App ID in developer portal under "Certificates, Identifiers & Profiles" to the next format "XC com mycompany appname" (in case your app ID was com.mycompany.appname) helps Xcode see your appID. Strange but it's working.
