crash: wkwebview and this plugin not happy

See original GitHub issue

I am using version 0.7.2 with ionic’s wkwebview plugin.

On start the apps crash with the following information:

2017-08-09 12:32:05.461888+0200 Cochrane+[734:238485] Apache Cordova native platform version 4.4.0 is starting.

I’ve logged this as well over here and a comment was to:

I have modified a fork of it for myself but basically you just need to comment the lines as below in the background-mode plugin and it will work fine:

 /**
*forKey:@"_requiresUserActionForMediaPlayback"]; * causes crash on ios10 with wk
*
* [obj setValue:[NSNumber numberWithBool:NO]
*        forKey:@"_requiresUserActionForMediaPlayback"];
*/

Any ideas on how to properly fix this going forward?
