I'm curious about how this PR works. What are the magic strings for, and why does setting them in WKWebViewConfiguration make a difference?

[heikomat]

@l3ender As can be determined by the followup lines, these are base64 encoded strings.
The first one decodes to
alwaysRunsAtForegroundPriority
and the second one to
_alwaysRunsAtForegroundPriority

[l3ender]

@heikomat Thanks for the response. Don't know how I missed that (not fluent in Obj C, but still pretty obvious).

Why do the strings need to be encoded?

@l3ender As can be determined by the followup lines, these are base64 encoded strings.
The first one decodes to
alwaysRunsAtForegroundPriority
and the second one to
_alwaysRunsAtForegroundPriority

So if Apple ever decides to rename those functions this preference will break silently?

Isn't this a really bad idea? Looks like there's some details in #286

This is a terrible idea. The strings are base64 encoded so Apple's AppStore review scan will generally pass right over them. If Apple finds this, they'll reject and possibly mass-reject/pull any ionic apps using wkwebview.

This should be changed immediately as it is in direct opposition to the AppStore review guidelines.
