I have a storyboard that worked fine in Visual Studio until the xamarin update that came with xcode 8.2. Since then, it appears the file was severely changed by the designer because if I open the previous version from TFS it opens fine and then it's modified by the designer and then it cannot be opened anymore. So the designer is mucking with it severely to a point where it's broken. this is severely blocking. File is attached.

I was able to successfully reproduce the error dialog that you have attached to this bug when using the attached storyboard file (thank you for including that).
1) Download Main Storyboard file
2) Create an iOS project from template
3) Replace default storyboard file with downloaded file
4) Wait for build host to connect
5) Open the file
Expected: Storyboard is visible and can be modified
Actual: Error dialog appears
error dialog from my repro:
Fixed and backported to C9 and C8.
If a workaround is urgently needed you can avoid the problem by opening the storyboard in Xcode and then disabling the 'refresh' control for every UITableViewController.
Hi, I have verified the fix in C8 and C9 using the same storyboard provided by the user. Environment information is included in the screencasts:
Ben, thanks for the speedy attention and fix that will benefit all others. Even more thanks for providing a reliable work-around. I was able to open the storyboard in xml and remove the refreshcontrol. Turns out it was not needed anyways in my application. now I can edit my storyboard again.
