Known Issues

  • The background downloader services (using the NSURLSession APIs) may cause occasional crashes in your applications due to an iOS bug. This bug has been reported to Apple, but is still unfixed as of iOS 8.1.2. There is no known workaround. For this reason, Pugpig does not use the background downloader services by default. You can explicitly enable them as explained here.
