When I optimize the performance of web request related to the wms serivce,
there are lots of "queueing or stalled" in chrome "Timing".
Due to map app, there are a lot of synchronous requests for the tile
resource.
If tile resources are all from the same host, it reaches browser connection
limitations occasionally.
The "queueing or stalled" occurs and then the timeout or broken, I guess,
may happened in the wkwebview.
The problem herein may caused by "browser connection limitations".
There are some related urls hereunder for your reference.

So try to add different hosts for the same resource such as
tile1.yourserver.com
tile2.yourserver.com
tile3.yourserver.com
tile4.yourserver.com
tile5.yourserver.com
...
instead of one "tile.yourserver.com"
