The site was shut down on 19 July and Apple was forced overhaul its database and server software to prevent future breaches.
The website is used by when third-party developers creating apps on iOS 7, OS X Mavericks. It also guides developers in putting their apps to beta testers, and comes with developer-only forums. Apple's developer site also houses sensitive financial information, which is encrypted.
Balic has, however, insisted that his intention was to reveal the vulnerabilities in Apple's website.
Balic has posted a video on Youtube as well which shows the hack and Balic accessing developer information from the website.

Balic insists in the video that the he has reported all the bugs to Apple and that he did not mean to damage the prestige of the company.
"I have reported all the bugs I found to the company and waited for approval," he said.
Balic says he only accessed the data to see how far he could go with the 'penetration test' ( a method of evaluating computer and network security by simulating an attack on a computer system or network from external and internal threats ) and that he will deleting all the data.
Balic told the Guardian, that "My intention was not attacking. Just after my reporting dev center got closed. I have not heard anything from them, and they announced that they got attacked."
Apple has not confirmed whether Balic was the hacker.
