These guys are total spoofers. Firstly the bug was noticed by the open source devs at AFNetworking a month before. They've announced a vulnerability before devs can get a patch out. Spoofers and con men.
I never sign up to iCloud on setup. I can access that stuff later. Apple seem to be doing two amateur programming errors here: a network call that never times out ( you have to go out of your way) and one which seems to lock the main thread.
VS is better and Xcode is pretty good when it works. My "snarky" comment refers to the frustrations about its cycle of stability and instability. It was super robust until 4.0 and then has gone in cycles of full and point releases regressing and stabilising. Rinse and repeat.6.2 was good.
