Environment

• CLI: 5.3.0

• Cross-platform modules: 5.3.1

• Android Runtime:5.3.0

• iOS Runtime:5.3.0

• Plugin(s):

  "nativescript-3dtouch": "^1.2.2",
  "nativescript-angular": "^7.2.3",
  "nativescript-camera": "^4.4.0",
  "nativescript-fingerprint-auth": "^6.2.0",
  "nativescript-localstorage": "^2.0.0",
  "nativescript-plugin-firebase": "^8.1.1",
  "nativescript-theme-core": "^1.0.4",
  "nativescript-vibrate": "^2.1.3",

Describe the bug
after running tns run ios --emulator any changes thereafter appears to crash and reloading needs to be executed manually by closing emulated/virtual application and reloading it.

Occurs after updating Nativescript and plugins 5.3.0. See crash report below

To Reproduce
tns run ios --emulator

Expected behavior
Reload after changes shouldn't crash.
