Vratislav Holub In June, on the occasion of the opening keynote for the developer conference WWDC 2020, we saw the presentation of the upcoming operating systems. Of course, the limelight and the astonishment of apple lovers in this regard was managed to get iOS 14, which brings to users the option of widgets right on the desktop, a list of App Library applications, where the programs are categorized accordingly, the Picture in Picture function, a significantly better notification in case of incoming calls, a new graphical interface for Siri and many others.

After months of testing, we finally got it today. The Californian giant has already released the Golden Master (GM) version of the aforementioned iOS 14 operating system for developers, together with iPadOS 14, watchOS 7 and tvOS 14. If you haven't heard of the GM versions yet, they are almost complete systems that could potentially be issued as public. In this phase of testing, only the final touches are being tweaked and then the first official version is released to the public. If no bugs were encountered in this GM version, it would then be released as an official version. It could therefore be said that already in the current situation Apple has practically ready-made systems available, and therefore we can expect an official release in the very near future, namely tomorrow.
Developers can already download the IPSW files of the mentioned operating system through the Apple Developer website. If you have a developer profile installed on your iPhone, you can download the update in the classic way via Settings -> General -> System Update.

After installing the GM version, iTunes stopped "seeing" my iPhone. No problem in all previous betas. I have Mojave and I don't want to install Cat because of the foun. and above. Hopefully there will be a patch. Does anyone have something similar?
… and was there a patch waiting to be installed?. Everything is OK
Good day, I don't see any support for writing in the Apple pencil, e.g. in the search engine or maps :(
