Q:

the ios designer mac agent is not available

Hi am using visual studio 2015 community to create ios app.I am getting this error all time like the ios designer  mac  agent is not available.I am using win-7 64-bit os.

A:

You have to have a Mac paired with your Windows OS in order to utilize the iOS Designer.
Xamarin.iOS Requirements:

Windows 7 or higher.

Visual Studio 2012 Professional or higher.

Xamarin for Visual Studio.

A Mac running OS X Yosemite (10.10) or higher (although we recommend the latest stable version).

Xamarin iOS SDK.

Apple’s Xcode(7+) IDE and iOS SDK (we recommend the latest version from the App Store).

The Windows computer must be able to reach the Mac via the network.

Xamarin.iOS for Visual Studio accomplishes an amazing feat: it lets you create, build, and debug iOS applications on a Windows computer using the Visual Studio IDE. It cannot do this alone – iOS applications cannot be created without Apple’s compiler, and they cannot be deployed without Apple’s certificates and code-signing tools. This means that your Xamarin.iOS for Visual Studio installation requires a connection to a networked Mac OS X computer in order to perform these tasks. Once configured, Xamarin’s tools will make the process as seamless as possible.
