The iOS SDK version '...' is not installed, and no newer version was found

Question

I get the error after updating Xamarin in Visual Studio which I had to do after a git pull. I have also applied the Xamarin updates in Xamarin Studio on my Mac build host. (Xamarin Studio > Check for updates).

The iOS SDK version '9.2' is not installed, and no newer version was found.

Answer 1

You can also modify the SDK version of your iOS project from visual studio in order to support older SDKs where you cant update the XCode or SDKs.

1. Open iOS project properties from Visual Studio.
2. Open iOS.Build tab
3. Set SDK version to 'Default'
4. Set Link Behaviour to 'Link Framework SDKs Only'
5. Save and Run the project

Answer 2

XCode needed updating to get the latest SDK.

The App Store told me there were updates, and mentioned SDK 9.2 in the summary so I updated.

It appears the cause was a commit on the csproj that bumped the SDK.

Answer 3

You can manually edit .csproj file and replace <MtouchSdkVersion>9.2</MtouchSdkVersion> with the version you actually have on your mac. This can be a solution when you use an old OS which does not offer updates for XCode.
