Ahh, sorry, I missed the Xamarin part.
So, in general we saw significantly slower builds for some projects with Xamarin + Xcode 8.2
We worked with other users to see if there’s anything we could do, but it seems to be a Xamarin issue, where Xamarin + Xcode 8.1 compiled the same project significantly faster than Xamarin + Xcode 8.2, although in general Xcode 8.2 is faster for native iOS projects.
This might or might not be an issue in your case, as it doesn’t affect all projects.
Things to try
Managed Linker configuration
One thing might worth a try is to change the “Managed Linker” configuration in your Xamarin project settings (http://blog.bitrise.io/2016/09/10/weekly-vm-updates.html)
- In Xamarin Studio’s project navigator open your iOS project’s Project Options (by double clicking on the project/rigth click Options).
- Select iOS Build in the side menu
- Change the Linker behavior (in the Code Generation & Runtime section)
Switch the Xamarin Stack to another Xamarin channel stack
Try to build on the
Xamarin Alpha stacks, we have a stack for all three Xamarin channels, updated every week to the latest update of that channel.
