Can you attach the full build log to the bug report along with all version informations*

Also attaching the registrar.m file** would be useful as UISearchBarDelegate is not a new (or even recent) type and the actual error could be located in the lines before this one.


* The easiest way to get exact version information is to use the "Xamarin Studio" menu, "About Xamarin Studio" item, "Show Details" button and copy/paste the version informations (you can use the "Copy Information" button).

This is a new bug.

I've been building this project with this configuration since 2012. I include iPhoneOS6.1.sdk in the Xcode SDKs, and build for 6.1.  

Unfortunately, the last build that I did was in March.  I only work on it when I need to do an update, such as to get it to work for iOS 9.

Comment 5 Rolf Bjarne Kvinge [MSFT] 2015-09-21 04:12:16 UTC
You're building using the 6.1 SDK:

> 		Xamarin.iOS 9.0.1 Business Edition using framework: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk

and UIBarPositioningDelegate was introduced in iOS 7.

You need to build with at least the iOS 7.0 SDK (but we recommend you always build with the latest SDK for the Xcode version you're using; this can be done by selecting 'Default' as the SDK version in your project's iOS Build options).

That said we need a better error message; and that's already been reported as bug #24677 (thus marking this as a duplicate).

Like I said before, this is a new bug.  I've been able to build with this configuration for a couple of years.  Now with the latest version (don't know exactly when it broke, sometime after March 2015), it doesn't work.

Since I'm denied access to bug 24677, I can't say yes or no that this is a duplicate of it, but from the sounds of it, I don't think so.

It's not a bug, it's a requirement: if you update to the latest Xamarin.iOS, you'll also have to build with the corresponding iOS SDK (in this case iOS 9) [1].

Bug #24677 is just an enhancement request to get a better error message for this scenario/requirement.

[1] Unless you enable the managed linker (in the project's iOS Build options, set "Linker behavior" to "Link SDK assemblies" or "Link all").
