Debuging on iphone - can linking to Safari cause problems

I am trying to debug my app on an iPhone 5c. When I link the device to Safari on the macbook it appears to generate errors whereas without the link to the macbook the app seems to behave as expected.

So I am not sure if I am seeing real errors using the macbook or problems caused by the cable link.

Has anyone else experienced this?

Inspecting via Safari should not really influence the program.

What kind of errors are you seeing?

The main problem seems to be with polyfills.js “Error:Network Error”. Reading on the net seems to be an issue which seems to popup at random. Only thing is I am not sure that polyfills is the cause of the error or some bug in my code causing it to fail.

I have already taken out all the toast calls - they worked fine in Android but on the iPhone I kept getting:

removeView was not found

so by removed all the toasts no “removeView not being found” are generated.

What exact code is causing what exact error message?

And standard question in such cases:
What is your ionic info output?

That’s the main problem the polyfill error appears on it own - running the same code over and over again fails to report it.

At this stage I really wanted to see if anyone had the same problem if not it’s a case of separating the code in question and checking line by line.
