Description Jon Goldberger [MSFT] 2013-09-19 19:21:13 UTC
Each time I start an app in the iOS debugger, after the FinishedLaunching delegate occur, I see errors that are not coming from my app.

it happen only on the debugger. I am running the last alpha version of Xamarin.

is there a way to remove those errors and is something wrong with my config ?

Comment 1 Rolf Bjarne Kvinge [MSFT] 2013-09-20 03:57:37 UTC
This is a bug in Apple's frameworks. Note that it only happens in the simulator (and the messages are harmless as well).

The only known workaround for the moment is to enable the linker in the project's iOS Build Options (set "Linker behavior" to "Link SDK assemblies only"), but the build speed will suffer significantly.
