Build failure with Xamarin.Forms 4

[sander1133]

In Xamarin.Forms 4 i get the build error: Can't resolve the reference 'UIKit.UIBarButtonItem Xamarin.Forms.Platform.iOS.ToolbarItemExtensions::ToUIBarButtonItem(Xamarin.Forms.ToolbarItem,System.Boolean)'.

Seems like something has changed in de the Xamarin Api.

ToUIBarButtonItem has gained an extra parameter. Both are optional so I'm not sure why it fails but that passing false as the second parameter should work.

https://github.com/xamarin/Xamarin.Forms/blob/0a67f8b0a105fbf56b6ac704cfc283840a189817/Xamarin.Forms.Platform.iOS/Extensions/ToolbarItemExtensions.cs#L12

EDIT Optional parameters are inserted at compile time, so adding an extra optional parameter is as breaking as adding a non-optional parameter).

Yep, same problem with recent 3.5 release. Guess we just need a recompile and publish @jsmarcus
