Update to 7.1. Apple, what’s wrong with you?

For the third day I am trying to:
- update my iPhone and iPad to iOS 9
- update Xcode to 7.1

Slow like in early 90-ties. Then, after many hour and few percent downloaded, update breaks. Then again.

NO WAY to do that. Apple, what is wrong with you again?

I am not saying my Macbook or Mac Pro are bad products. I am not saying that Xcode is bad product.
What I am saying that without the possibility to perform normal upgrade, those all are UNEXISTING products to me.

firstmiro about Xcode, v7.0
