When you submit it, you will automatically receive a letter titled "We got it!" The confirmation email. If you haven't received it, it may mean that the submission was unsuccessful. But please don't give up immediately, because not receiving the email does not exactly mean that the submission failed. It may be a problem with the Gmail system (although this is extremely rare).
If you want to finally confirm your submission status, it is recommended that you first adjust your mentality, and then visit https://developer.apple.com/swift-student-challenge/apply/ and log in to your Apple ID account. After logging in, you will enter a new interface:
If the page title is "We've received your submission.", then congratulations, your submission has been successfully received, and you can rest assured.
If the content displayed on the page shows that you have not submitted it yet, then unfortunately, it is almost certain that your submission was unsuccessful.
If you confirm that you have failed to submit successfully, don't give up completely. You can try to contact Apple's official support (swiftstudentchallenge@apple.com)
for help. However, it should be noted that the possibility of approval is low, because Apple needs to maintain fairness to all participants, and the official agreement has clearly stated that they are not responsible for damage or failure caused by technical problems in the submission process.
Finally, adjust your mentality. You may feel regretful or regretful, but please believe that this experience will be a part of your growth. Even if you fail to submit it successfully, don't be discouraged. There will be more opportunities in the future. I have encountered a similar situation and been troubled, but I still choose to continue to work hard to meet the next challenge. I understand your feelings and sincerely wish you good luck!
