iOS 9 source code leaked, why isn't Apple worried at all?
Recently, the source code of Apple ios 9 was leaked, and many people are worried whether hackers will use these source codes to find out the vulnerabilities in them and create iOS system viruses. iOS 9 is actually two years old, Apple has now upgraded to iOS 11 and has less than 7% of iOS devices running now with iOS 9 and previous versions. Older devices upgraded to iOS 11 are going to be laggy and have a lot less battery life compared to iOS 9 & 10 though. But all the bugs that should be patched have been closed, and iOS 11 already stands at 65% of users and iOS 10 at 28%, so this leak is not enough for Apple to fear.
