Crash when using iOS back button in {N} 3.1

Did you verify this is a real problem by searching [Stack Overflow]

Yes

Tell us about the problem

After updating {N} to 3.1 (from 3.0.1) the native back button in iOS crashes, this wasn’t an issue in 3.0.1 and I’m pretty sure it isn’t code related since there is very little code involved. I’m using the standard {N} router with no additional code other than a programmatic router link: this.router.navigate(['/detail', selectedItems[0].id]);

Error in terminal:

Not that I am aware of

Ah, found the issue!

I upgraded my project using the tns upgradecommand.

I still had nativescript-angular": "~3.0.0" instead of "nativescript-angular": "~3.1.0" and "nativescript-telerik-ui": "^2.0.1" instead of "nativescript-telerik-ui": "^3.0.3" in my package.json. Upgrading Angular and nativescript-telerik-ui fixed the issue.

@mikelinden1 Did you also try to upgrade “nativescript-telerik-ui”? I think you have the same version I had to reproduce this Issue.

[simonox]

I will try to reproduce this issue.
