Hi Team,

I have updated to Xamarin.iOS 8.6.0 and and installed Xcode 6.1.1. After that I am unable to build the application on the device. I am getting MTOUCHTASK: Error MT5206: Failed to create the a fat library. Please review the build log. (MT5206) error every time.
If you have any resolution steps please let me know.

But it's working fine in simulator.

    I have checked Xamarin Studio->Help->Open Log Directory. But I canot see any build logs there. Can you please tell me where exactly I can see those logs?

    Hi @SatyaPrakashParida,

    If you view the Errors pad, the last option is to view the Build Output. See the attached image.

    @FreFre Thanks, your solution worked for me. After heavy updating of my environment, got the same error. Launched XCode, accepted the agreement, installer did some final lifting - Problem solved.

    Thanks FreFre. Using Visual Studio, just had to start XCode on the Mac and accept the new license. Wonder why they can't display a more meaningful message?

    Starting XCode and accepting the license agreement worked like charm. Many thanks!!

    I am having same issue. Failed to create the a fat library. Please review the build log.
    Build log is saying
    unable to find utility "lipo", not a developer tool or in PATH

    I had reopened the visual studio. Also run Hello XCode project in xcode on mac. still getting the same error. My project was running successfully yesterday but today morning getting this unexpected error. Please help.

    I fixed this issue today by opening Xcode, going to Preferences, going to Locations and then changing the command line tools back to 8.2.1 from 7.3.1. I'm guessing that the latest Xamarin update must have inadvertently changed them for some reason.

    It worked, thanks :)

    I got the resolution. Xamarin was unable to select the default X Code version. Done it by changing "sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer" command.

    Thanks its work for me.
