Apple this morning released sixth betas of iOS and macOS for developers.
iOS 11.2 beta 6, build 15C114 is out, along with macOS High Sierra 10.13.2 beta 6, build 17C85a. These betas come after the fifth betas were released earlier this week, on Tuesday. The quick turnaround suggests an imminent public release soon.
No word on what’s new yet, but stay tuned.
