Hi,

I ran into this problem with the InAppBrowser Plugin (@ionic-native/in-app-browser) after I tried to refactor a feature of my app. I extracted a part of the functionality of a page to a service provider.

In Android everything still works fine, but iOS execution is stopped right after the splash screen is shown with following error:

> “ReferenceError: Can’t find variable: InAppBrowser”

(line number pointing to the constructor arguments of my new service provider)

constructor of my service provider

```auto
constructor(
        private localizationService: ILocalizationService,
        private basketService: IBasketService,
        private iab: InAppBrowser,
        private platform: Platform,
        private injector: Injector
    ) {}

```

app.module.ts  
providers:[  
…

```auto
 {
      provide: 'ICheckoutService',
      useClass: CheckoutService,
      deps: ['ILocalizationService', 'IBasketService', InAppBrowser, Platform, Injector]
    }
]

```

Before I had the 3 constructor arguments injected in a Page/Component, where it worked perfectly fine…  
I know I could go back to the last version of the code, but that component was seriously cluttered, a refactoring had to be done.

I have absolutely no clue what’s wrong and where it may fail and I would be very appreciative of any pointers or hints.

I already tried removing/reinstalling the plugin, same with the ios platform… even deleted the node\_modules and reinstalled all npm packages which did nothing 😕

Thanks in advance!
