The information comes from an internal iOS 13 system images, which was released to developers on Thursday. This is the seventh iOS 13 beta version rolled out to developers and the clue buried inside the code has more significance than a tip from an internal source or a rumour.

According to the report, iOS 13 roll-out date was also hidden in the iOS 13 beta source codes, which suggest it will be rolled out on September 23, 2019.
