I am interested in using iCloud for Windows for syncing bookmarks between Windows browsers (as a replacement for Xmarks, which is shutting down). I installed iCloud for Windows and used my AppleID to log in, but it said I needed to first use an iOS device. I do not have an iPhone or iPad, nor intend to have, so maybe the iOS simulator in Xcode could be enough for this purpose of mine. So my question is: does Xcode's iOS simulator allow me to sign in my AppleID account? Or does it work "offline", account-free?
Yes, it is possible to sign-in to iCloud via iOS Simulator. Simply launch the Settings app and click on Sign in to your iPhone to log into iCloud.
