Xamarin.Apple.SDK update log file
I'm running Win7-64 on a very stable dual Xeon box with 128GB RAM and RAID hard drives.
I had 5 updates in Extensions and Updates for 'Xamarin Preview' I was able to install 3 of them such as the Xamarin.Android.SDK.
I got a VSIX Installer "Modification failed. Some modifications could not be applied successfully. for the VERY IMPORTANT Xamarin.Apple.SDK.
I'm including the log file.
When I went back into Extensions and Updates, Xamarin.Apple.SDK no longer shows as needing an update?
I was also unable to install the Mono Debugging for Visual Studio update. When it ran in VSIX, I got a dialog 'VSIX Installer' "The selected extensions are already installed to the specified SKU"
So 'Mono Dbugging for Visual Studio' is stuck in my Extensions and Updates for Xamarin Preview. I've tried several times.
Xamarin.Android.SDK shows up as installed and in the 'About Visual Studio' dialog, but Xamarin.Apple.SDK does NOT show up in either the Installed Tools and Extensions or the the 'About Visual Studio' dialog.
Thanks so much for taking the time to submit this report! I am able to reproduce this issue. Marking this report as CONFIRMED.

Prashant - glad to help! How can I get these installed? Will there be an update in the next few days that will fix it or should I un-install Xamarin and re-install?
I'm not sure if you're still facing this issue, but please uninstall and reinstall Xamarin in this case.
