Ios build instability problem

Continuing the discussion from app does not load information from the webserver IOS:

Hello
With this header parameter (“Access-Control-Allow-Origin: *”); it worked in some queries, so i put all the other calls on the webserver, there would be some more solution because i have a problem handling the data coming from the server we always work with json

Here’s where having the error messages will be a big help. Any messages on the remote Safari Console?
