Could you post the full version information from Xamarin studio? - Prashant Cholachagudda
@PrashantC I update the question see my edit. I think the problem must be with Xcode update. - Harshad Pansuriya

It's an issue with latest XCode release, we do not support XCode v8.3 in the current stable release. (see https://releases.xamarin.com/technical-bulletin-xcode-8-3/)

You may want to rollback to previous version of XCode to use the iOS designer

Prashant C is correct. Updating to the latest version fixes it.

In addition when using Visual Studio 2017 on Windows I had the same issue. Upgrading Xamarin (stable channel on mac & windows) and updating Visual Studio 2017 to the latest version (15.0.26228.12) fixed it for me.

Here is my opinion regarding this issue. My best advice is to NEVER use the IOS designer. It's rubbish. Always use Xcode Interface Builder. The main reason is, you're guaranteed the storyboard will be valid with IOS. I once created an empty storyboard in IOS Designer and compared the XML it generated to an empty storyboard created in Xcode. It was totally different. The designer version was missing a hell of a lot of information. Since then I have never trusted the IOS designer. Not only that, but constraints are pain in the ass to use on the IOS designer, whereby, they're a lot easier in Xcode. I've also have storyboards render totally wrong in the IOS designer if the layout is particularly complex.
