AFAIK, you cannot forcibly tell GC to collect your garbage. GC.Collect may or may not collection what we expect it to. But, I do see that there is a clear behavioural difference in GTK and iOS when calling GC.Collect after popping a page.

[knocte]

As explained in the original report (mono/gtk-sharp#269) this might be related to not releasing delegates from event handlers (so not related to GC actually).

Taking into consideration the remaining lifetime of Xamarin.Forms, the platform this is about, the age of this issue and the traction this issue has seen I think it's unlikely that this will get fixed. If it is something that you still would like to have, please consider opening a PR. Thanks!
