Hi,
I updated my iphone6 to be ios8.4 and it was not eligible for the xcode 6.3.2.
Somehow, my app store does not show me that I can update to xcode 6.4 (in fact it is telling me that I installed 6.4 already. I was shocked…)
So I am downloading xcode 7.0 beta right now (version as of today 7/27/2015).
I hope everything go smooth but please let me know if there is anything that I have to know in advance.
