I've embedded a dublin theme'd application into a customized outsystems-now shell via xcode and am having some performance issues when trying to run the application both natively on the device or via the xcode emulator.  The app takes over 30 seconds to get to the login screen. 

There are not very many other resources I can find related to performance issues with outsystems now but I did find this post (http://www.outsystems.com/forums/discussion/16902/slow-apps-on-safari-and-ios-9/) articulating that it might be due to custom fonts.

Has anyone else experienced performance issues with the OS now shell and been able to successfully resolve them? Any help would be appreciated.

Hello
 
Sorry for the late reply.
Much like Marco said in his post, Apple changed the way web applications are loaded in devices running iOS9+, in particular resources (JavaScripts, CSS, Fonts). The issue affects both Safari and applications using web views (which is the case of OutSystems Now). While retrieving all page resources, the browser sometimes stalls for around 30 seconds.

We were able to reproduce the problem (using several Javascript files and one CSS with @Import tags) and submitted that information to Apple but they haven't issued an official fix yet (nor have given any prevision date for it). 

Having said that, we're actively working on a solution for this problem.
 
Meanwhile, as a workaround, try to minimize the usage of some resources (e.g.: Fonts).
Sorry for the inconvenience.
