Livesync crashes app every OTHER time on iOS with 3.0.0-rc.2

[alexziskind1]

Description

When using the new 3.0.0-rc.2 branch with iOS simulator, the livesynced app crashed every other time (literally every other time).
I make one change, the change breaks the app. I make another app, the app livesyncs successfully, after a third change the app crashed, etc.

Which platform(s) does your issue occur on?

iOS only

I created a new app:
tns create rctest
Ran the app
tns run ios
Made changes to the javascript code.
Received the following error on the console (the app itself crashed)

@alexziskind1 Can you please try:

tns create rctest --template tns-template-hello-world@rc
tns platform add ios@rc --path rctest (we released 3.0.0-rc.2 last week)
tns run ios --path tctest

{N} 3.0.0 include breaking changes and template is also changed (and released with @rc tag).

[alexziskind1]

Hi @dtopuzov
I tried your suggestion, but received the same error when I made a change in the running app.

[dtopuzov]

@alexziskind1 I still can not reproduce the issue.
Can you please post exact package.json of your app?

[alexziskind1]

Sure. This happens with any app I try on my machine. I've tried your template. Now I'm able to reproduce the problem with the nativescript groceries app too. Here's the package.json from the groceries app based on the groceries template.

Confirmed this is still a problem with the 3.0.0 release. But, you probably are already way ahead of me on this one. :)

[dtopuzov]

Hi @alexziskind1 we are working on the problem and we will provide fix soon (in first hot fix release after 3.0.0).

[dtopuzov]

Hi @alexziskind1 fix is already available in master, can you please try:

npm un -g nativescript
npm cache clean
npm i -g nativescript@next

I hope we will release it in official release by the end of this week or begging of next week.
