Hi @reposooo. Thank you very much for raising this issue.

It turned out that it is the same as the one we've already fixed with https://github.com/NativeScript/ios-runtime/pull/1019. Unfortunately due to some infrastructure problems which we detected today there was no @rc package published to NPM. Hopefully in less than a couple of hours there'll be a new RC package published with which you can test to confirm whether it fixes it.

To install the latest @rc version you'll have to remove your platforms/ios directory and execute tns platform add ios@rc

@mbektchiev seems like it needs a bit time to be able have that fix though @rc how can i pull that fix now and test it?

[mbektchiev]

It has already been published as @rc and @next:

npm view tns-ios dist-tags --json
{
  "latest": "5.0.0",
  "next": "5.1.0-2018-11-26-121836-02",
  "rc": "5.0.1-rc-2018-11-26-133512-03",
  "test": "4.3.0-2018-08-22-01"
}

In order to test it you need to recreate the platforms/ios directory as I mentioned earlier.

@mbektchiev works perfect! Thanks a lot!

Is the memory supposed to decrease between navigations? In my app--NS 5.1.1, iOS, Angular, with webpack--memory seems to increase steadily. If I hit a page that uses a lot of memory, the app stays at that level after I have navigated away (that higher level then becomes the baseline, and further memory use just sits on top of that). I have tried adding clearHistory="true" to the navigation, but that does not change this--memory keeps increasing throughout app use.

I believe this issue was meant to address this. Is there something else required for webpack?
