tns livesync ios --watch, app crashes when I change .css or .xml

[dajk]

Hi guys,

have a problem with livesync watcher. When I run the app as tns livesync ios --watch and change .css or .xml, app crashes. It happens only on iOS.

This is what I have in console:

Assertion failure in -[TKCollectionView _endItemAnimationsWithInvalidationContext:tentativelyForReordering:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3512.60.7/UICollectionView.m:4422

It works for me, can you give some more details:
{N} CLI version and tns-ios version
Xcode version
Device or Simulator?
iOS version

Also you can check if folder and project, it is known issue that we will try to fix for the next release.
See: #1770
