Creditors are not required to report credit card accounts on your credit reports. However, that would be rather unlikely in most cases; it could be that the creditor is simply slow in reporting your account and, as a result, you might want to give it an extra month or so.
Regardless, do not necessarily look for "Apple" on your credit report since the card is issued by Goldman Sachs Bank USA (or Green Dot Bank in the case of an Apple Cash card).
