I am having same issue. I am on xcode 16. I cannot see or add Call Directory in capabilities in either xcode or on developer site in identifiers. I set up Call Directory extension through template target. I cannot add blocking or caller id in app as I get message callkit not enabled. When itry to manually add com.apple.developer.callkit.call-directory call-blocking caller-identification i get provisioning error. Provisioning profile "iOS Team Provisioning Profile: "" doesn't include the com.apple.developer.callkit.call-directory entitlement.

On our paid Apple Developer Program account (role: Account Holder/Admin), the Call Directory capability toggle does not appear on any iOS App Extension Identifier we create. Because of that, provisioning profiles for those extension IDs never include the Call Directory entitlement and the extension cannot be enabled on device. That is the only reason we tried to add manually which does not work. Environment Membership: Apple Developer Program (paid, active) Xcode: [16.x] iOS devices tested: iOS 18.4.1, 18.5 and 18.6.1 App type: iOS app + Call Directory extension App Groups: enabled and working What I am not seeing In Certificates, Identifiers & Profiles → Identifiers → (iOS App ID, type App Extension), I expect to see a Call Directory capability toggle I can enable but it is not there What actually happens The Call Directory toggle is missing from the extension Identifier details page. Profiles created for the extension ID don’t contain the Call Directory entitlement. The extension never appears under Settings → Phone → Call Blocking & Identification. Calling the API at runtime fails with com.apple.CallKit.error.calldirectorymanager error 1. Evidence (redacted) Signed entitlements of the built .appex do not contain a Call Directory key: codesign -d --entitlements :- /path/to/YourExt.appex Output only shows team/app-groups (no Call Directory entry). The embedded mobileprovision lacks it as well: security cms -D -i /path/to/YourExt.appex/embedded.mobileprovision >/tmp/ext.plist /usr/libexec/PlistBuddy -c 'Print :Entitlements:com.apple.developer.callkit.call-directory' /tmp/ext.plist → key not found
