Please create a new report on
Developer Community or GitHub with
your current version information, steps to reproduce, and relevant error
messages or log files if you are hitting an issue that looks similar to
this resolved bug and you do not yet see a matching new report.
I won't be able to give a short example where this occurs, but what I've been experiencing is the following:
2017-03-15 10:25:12.555 ClimbTag.iOS[4059:1658310] *** Assertion failure in -[UITableView _endCellAnimationsWithContext:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit/UIKit-3600.6.22/UITableView.m:1594
Seems somehow related to a listview with sections after removal of a section.
Would be nice if you guys could take a look at what is going on there and why such assertion might be triggered....
Can you provide your full environment information for where this is occuring. And are there any crash logs or stack traces beyond the error message you posted?
The easiest way to get exact version information is to use the "Xamarin Studio" menu, "About Xamarin Studio" item, "Show Details" button and copy/paste the version informations (you can use the "Copy Information" button).
Sorry, no additional crash logs are available.

Without more information about your issue and how to reproduce it, it's gonna be hard (impossible) for us to investigate more.
We'd need like a small test case with your code, to understand the context in which this issue occurs or, as Tim said: "crash logs or stack traces beyond the error message you posted".
It's also possible this is a native issue, hence also happening in Objective-C/Swift and having the code could help us assert that (we/you could be a similar test case with Xcode).
In this case it would be a bug against Apple and we could certainly file a radar.
I'm marking this bug as NEEDINFO for now but if you can't provide more information we'll have to close it as NON_REPRODUCIBLE.
Sorry. I can't provide additional information at this time. Call it non-reproducible.
