Stable Release: 15.3.5 with Xcode 9 Support

We are releasing an update for our current major release called 15.3 into the Stable channel. This update adds SDK bindings and IDE compatibility for Apple’s Xcode 9 release.

This release is now available as part of Visual Studio 2017 version 15.3.5 and in the Stable updater channels for Visual Studio 2017 for Mac (version 7.1.5.2) and Xamarin for Visual Studio 2015.

Products Released

  • Visual Studio 2017 for Mac (version 7.1.5.2)
  • Xamarin.VisualStudio 4.7.9.45
  • Release Notes
  • Note: This release can be considered part of the Xamarin.VisualStudio 4.6 release series. It only adds IDE compatibility for Xcode 9. It does not yet include the other features from version 4.7.

Intentional Changes

  • [Xamarin.iOS] – “This version of Xamarin.iOS requires the iOS 11.0 SDK (shipped with Xcode 9). Either upgrade Xcode to get the required header files or set the managed linker behaviour to Link Framework SDKs Only (to try to avoid the new APIs).” This message will appear when building using Xcode 8.3 or older with Xamarin.iOS 11. The issue arises because Xamarin.iOS 11 is built to include the Xcode 9 symbols. The Xamarin managed linker can remove these unused symbols to allow building successfully against older versions of Xcode.
    • Fix: Update to Xcode 9, or enable the Xamarin linker by choosing a setting other than Don’t link under Project properties > iOS Build > Linker behavior.

Other Common Issues from the Xamarin 15.3 Release

In case it might also be useful for reference, here are a few other in-progress progress commonly seen issues being tracked by the Xamarin team from the Xamarin 15.3 release. This list is not exhaustive: It does not include every issue user-submitted issue reported since the time of the Xamarin 15.3 release.

  • 58226 (non-public) [Xamarin iOS Designer] – “MonoTouch.Design.Client.DesignerRemoteException: System.NotSupportedException: Could not parse xml” when attempting to open a storyboard or .xib file, for example after editing the file with Xcode.
    • Temporary workaround: Open the problematic file as text (for example via the context menu for the file in the Solution window), and then remove the device element from the top of the file. It typically looks something like:
      <device id="retina4_0" orientation="portrait">
          <adaptation id="fullscreen"/>
      </device>
  • 58829 [Xamarin.Android, Xamarin.iOS] – Application Output window flooded with “[Mono] worker parking, [Mono] worker unparking” messages when debugging with Android Emulator.
    • Temporary workaround: Set the MONO_LOG_LEVEL environment variable to message or higher.
      • For example, on Xamarin.Android in a command prompt using adb:
        adb shell setprop debug.mono.env "MONO_LOG_LEVEL=message"
      • For Xamarin.iOS, go to Project Properties > iOS Build > Additional Options > Additional mtouch arguments, and add:
        --setenv:MONO_LOG_LEVEL=message
