Xamarin Studio 6.3

This is a beta of the upcoming Xamarin Studio 6.3 release. These previews are unsupported builds to allow developers to test the new features, and to gather feedback and bug reports. Your help is very appreciated!

Apple Developer Account management

This release introduces the ability to manage Apple developer accounts and iOS/macOS code signing entitlements with Xamarin Studio. The new interface provides a way to view all development teams associated with an Apple ID, and displays a list of Signing Identities, and Provisioning Profiles for each team.

Browse to Preferences > Publishing > Apple Developer Account to add an Apple ID. Authentication of your Apple ID is performed on the command line with fastlane. fastlane must be installed on your machine for you to be successfully authenticated. More information on fastlane and how to install it is detailed in the fastlane documentation.

  • The login process doesn't support accounts with two step authentication turned on.

iOS

Debug App Extensions on Device

New in this release of Xamarin Studio is the ability to debug iOS App Extensions on device. However, in order to do this, you will first need to edit your Project Options for your existing App Extension project(s) and then change the Debugger Port setting located in the iOS Debugger settings page. It is recommended that you change the port to some value other than 10000 (or whatever port your main application is configured to use).

New App Extension projects will automatically be assigned a random debugger port to avoid this problem in the future.

Execution targets improvements

The iOS add-in is using new features of the Main Toolbar introduced in Xamarin Studio 6.3 to improve the user experience such as custom icons, tooltips and the ability to grey out execution targets.

We also improved our logic to always show you the devices that are connected to your Mac and tell you exactly why they are "unavailable" for deployment.
This is great because there are a variety of ways a device can be unavailable: wrong device family, wrong capabilities or an OS version which doesn't match the deployment target.
Now your device will show up in the "Unavailable Device" section and there will be a short explanation of the issue next to its name. If you hover your mouse over the device name a tooltip will often give you more details.

Execution Target Device Icon

Execution Target Unavailable Device

Mac Execution Target

Here's the list of all the changes:

  • New device icons in the Main Toolbar for iOS, watchOS, tvOS and macOS device targets.
  • When we cannot show simulators or devices, instead of showing "Default" we now have Generic Simulator/Device under a "Build Only" menu separator.
  • We now always show the "Device" menu separator in the toolbar, like we do for Simulator.
  • We now show a message to connect devices in the toolbar when none are.
  • Mac project now show an actual execution target named “MyMac” with an iMac icon instead of “Default” with an iPhone icon.

Audio Unit Wizard

The new Audio Unit Extension wizard adds 3 options to customize the Audio Unit project template's plist.

  • Audio Unit Type
    • Instruments
    • Generator
    • Effect
    • Music effect
  • Subtype Code: has to be 4 characters exactly
  • Manufacturer Code: has to be 4 characters exactly

Audio Unit Wizard

Remove TLS Provider option

TLS Provider is not needed in the iOS build options anymore because:

  1. AppleTLS is the default since C7 and support up to TLS 1.2.
  2. MonoTLS is limited to SSLv3 and TLSv1: both are being deprecated.

Note: Xamarin.iOS 10.4 release notes already mention MonoTLS is deprecated and that it will be removed in the future.

Other improvements and bug fixes

  • We now show a progress bar when deploying to device. This is especially useful for watchOS. (Requires Xamarin.iOS 10.5.0.323+).
  • We now use known OS versions from Xamarin.iOS to populate the deployent target dropdowns.
    The two advantages are that we can give you the exact minimum version for each App Extensions type, as well as avoid showing OS versions, based on Xcode, that Xamarin.iOS does not yet support.
  • Any image asset that exists within the Images.xcassets (or Assets.xcassets) directory that is not imported by the *.csproj file will be ignored by the build.

Debugger

  • Support for HelpLink in exceptions. If an exception has a HelpLink then clicking on More Information at the top of the exception dialog will open the link in the default browser.

    Exception HelpLink Support

Microsoft Identity

  • Xamarin Studio no longer needs to launch an external process in order to capture login details when signing in to your Microsoft account.

General

  • The New Project dialog now shows a list of recently used templates.

    Recent Templates

  • Xamarin.UITest project templates have been updated to the latest stable versions.

    • Xamarin.UITest 2.0.6
    • Xamarin.TestCloud.Agent 0.20.3
  • Many other bug fixes and performance improvements.

Other improvements and bug fixes

  • Update all templates descriptions.
