App stucks at splash screen when running with '--prod' build

I’ve been working on an app which consists of “in-app purchases”, “firebase dynamic links”, etc.
The app works fine in both android and ios, when I used to run the app using commands:

ionic cordova run android --livereload
ionic cordova build ios

But as soon as I run the app using ‘–prod’ in front of them the app used to get stuck on my splash screen/app.component.ts screen.

Some of my app’s structure looks like this:

My chrome inspector showing me this log (in dev mode only, by the way my app is working with this log - this is only for your information)

I’ve been trying to solve this issue for past 2 days, but I’m unable to figure out this issue.
Can you please help me out with this?

See this question on stackoverflow -

It is useful to check the console for JavaScript errors in situations like this. Use remote debugging in Safari, and make sure to refresh the application whilst the debugger is attached so that you don’t miss startup errors:

Random observation, don’t use Boolean as a Type. Use boolean

I got this in my safari debugger. Maybe this would help you out…!

Just for the sake of knowledge, can you tell me the difference between Boolean and boolean ?

Short version is that Boolean is an object instance. A good quote that kindof puts it in a nutshell

“And since the Boolean object is an object, it will also coerce to true, even if its internal value is false.”

My take on it is, it can lead to serious misinterpretations and errors.

I’m not versed enough in the internal process of Ionic / webpack etc. to know if that is remedied at some point, but it’s safe to say it’s an issue that can and should be avoided absent that knowledge.

But the fact that it’s an object instance, and will always resonate as true makes sense by its existing in the first place.

Did you find any solution? I am facing the same issue with ios versions < 11.0
