Preview: iOS 9/Xcode 7 Support – 2nd Preview

** UPDATE – A newer Xamarin Studio build has been uploaded as part of this preview to address an issue with Interface.Storyboard rendering issues with the iOS Designer. **

We are releasing our second preview with support for Apple’s iOS9 SDK that works with Xcode 7 Beta 3.  We are aware that Xcode 7 Beta 4 also became available today from Apple. We are digging into it now and hope to have our Beta 4 support either later this week or early next week. In the interim, we still wanted to release our Beta 3 support, as it provides working support for Xamarin.VS, which was not included in our first preview.

There is no target Stable date for iOS 9 support at this time, as we have to wait until Apple finalizes and publishes their support before we can release ours. That being said, we will be doing many additional iOS 9 preview releases between now and the final Apple release, so be sure to check back and see if newer versions become available in the coming months.

As with all our preview releases, this is not a product we officially support. If you encounter any issues, we recommend filing a bug in Bugzilla.


Known Issues 

  • [Xamarin Studio / Xamarin.iOS] – WatchOS 2.0 is not supported in these builds (WatchKit is supported, as it has been since Xamarin.iOS 8.9)
  • [Xamarin Studio / Xamarin.iOS] – New Xcode 7 features are not supported in these builds.
  • [Xamarin Studio / Xamarin.iOS] – OSX 10.11 is not supported in these builds.

Preview: Android M Support – 2nd Preview

We are releasing our second preview with support for Google’s Android M SDK. This build supports the Android M Preview 2 released by Google on July 9th.

There is no target stable date for M support at this time, as we have to wait until Google finalizes and publishes their support before we can release ours. That being said, we may do additional M preview releases between now and the final Google release, so be sure to check back and see if newer versions become available in the coming months.

As with all our preview releases, this is not a product we officially support. If you encounter any issues, we recommend filing a bug in Bugzilla. You can also jump into the discussions on the forum thread posted below.


Known Issues 

  • 31002 – [Xamarin.Studio / Xamarin.VS] – Users will have to manually make sure their minimum SDK version is set to v5.1 (22) or lower, instead of v5.2 (23), in order to deploy to M devices and emulators.

Products Released

  • Xamarin for Visual Studio 3.11.671 [Download]

 

Alpha Release: Cycle 5 – Service Release 3

We are releasing a preview of our next upcoming stable release, dubbed Cycle 5 – Service Release 3, to the Alpha channel. These builds contain a number of additional fixes on top of our current stable products, and we’re looking to get them into the Stable channel later this month if all goes well.

As this is an Alpha preview, there are still some known issues to be aware of. These are regressions against the previous stable release of Cycle 5 – Service Release 2. We’re looking to have these fixed in an upcoming preview, but felt they were not severe enough to hold back an Alpha containing lots of fixes people may be waiting on.

Preview: iOS 9/Xcode 7 Support

We are releasing our first preview with support for Apple’s iOS9 SDK that now works with Xcode 7 (the iOS 9 Stable hotfix was only for Xcode 6).

There is no target Stable date for iOS 9 support at this time, as we have to wait until Apple finalizes and publishes their support before we can release ours.

Stable Release: Cycle 5 – Service Release 2

The previously released Cycle 5 – Service Release 2 builds from the Beta channel have finished their testing runs and are now ready for release to the Stable channel. There have not been any additional fixes added since the updated Beta release last week.

Please check the product release notes for a full list of fixes to each product included in this release. Included in this release is the fix to Stable from last week for iOS 9/Xcode 6, so if you had previously updated to that, there is no danger in regressing if you move to these stable builds.

*UPDATE: The Xamarin iOS version for Stable has been upgraded to 8.10.3.2, which supports iOS 8.4 and Xcode 6.4.

Beta Release: Cycle 5 – Service Release 2

** UPDATE – A newer Beta build if Xamarin.iOS has been uploaded to the Beta channel, which addresses the previously described known issue with incorrect MT3001 errors. **


The previously released Cycle 5 – Service Release 2 builds from the Alpha channel have had additional fixes added to them and are now ready for release to the Beta channel. New fixes since the Alpha release are listed below for each product, and we’re still hoping to do a Stable release of these products around the end of the month if all goes well.

While we like our Beta releases to be as flawless as possible, there was one issue we found very recently that needs attention before these builds go to Stable, but we felt it was best not to block the entire Beta release for that one issue. We’ll be putting out an updated Beta with patches to address this known issue soon, but for the time being please be aware of it when using the iOS product.


Products Released

*Note: The build number for Xamarin Studio remains unchanged from the Alpha channel, so if you already are on the Alpha of Xamarin Studio and move to the Beta, the updater will not prompt you to download anything for XS.

iOS 9 / El Capitan Preview Technical Bulletin

Yesterday Apple released the first previews of both iOS 9 and OS X El Capitan. We are working full-speed to add support for both iOS 9 and El Capitan right now, and we’ll keep you posted as things progress.

For iOS 9, we are investigating an issue that is causing a number of Xamarin apps to crash on startup. As we’re digging into this, the issue seems to be specific to apps that include 32-bit support.

Apple made some dramatic changes to OS X by making /usr/bin read-only, even with root access, so we’re working on making support for Xamarin Studio and the Xamarin Installer available as soon as possible to get up and running on OS X El Capitan.

As always, these are preview builds and we recommend staying with the stable releases of Xamarin and OS X and iOS until we make full support available for these previews available via this release blog and their preview sites.

Update: We have identified two issues that will affect both 32-bit and 64-bit apps on iOS 9. This has been released as a hotfix which you can find more detail on our hotfix blog post.

Android Hotfixes for Android M Preview

We have pushed a new Xamarin.Android SDK release and accompanying IDEs tools to the Stable channel to provide a few additional hotfixes that were needed based on the new SDKs provided at Google I/O.


Issues Addressed

  • 30555 – New “preview channel” build/sdk tool paths can now be processed
  • 30562 – Aapt path has changed in the latest build tools release
  • 30566 – Fixed an issue with java.lang.String throwing “java.lang.UnsupportedOperationException: Use StringFactory instead.” for most common constructors.
  • 30653 – Deployment failed because of an internal error: File name has not been set is now fixed.
