Beta Release: iOS 9 Support – Service Release 1

We are releasing new Beta builds to further address some issues with our previously released iOS 9 support

As this is a Beta, there may still be issues present, and others we may find as time goes on. Please use the below forum threads to report and monitor issues that may occur, and find any potential workarounds that may exist.

UPDATED – Beta Release: Xamarin iOS Support for iOS 9

UPDATE – Newer preview builds of Xamarin Studio, Xamarin.VS, and Xamarin.iOS are now available in the Beta channel. Build information updated below. The Mono Framework MDK remains the same as the previous Beta release. 

Be sure to check out the associated documentation we have available for iOS 9, and our Xamarin Blog Post

We are targeting a Stable date for iOS 9 support of September 16th, to coincide with Apple’s final release. 

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.iOS] – F# Single View template crashes on launch.
  • [Xamarin Studio / Xamarin.iOS] – WatchOS 2.0 is not supported in these builds.
  • [Xamarin Studio / Xamarin.iOS] – OSX 10.11 is not supported in these builds.
  • [Xamarin.VS] – Building with an iOS class library that uses string resources fails.
  • [Xamarin.VS] – WatchKit Application in Glance mode does not die after clicking stop.

Products Released

  • Mono MDK Framework


Beta Release: Cycle 5 – Service Release 4

We are releasing the Cycle 5 Service Release 4 builds to the Beta channel. Normally these builds would go to the Alpha channel first, but as we are using that for an advance preview of our next major feature release, we’re moving the Cycle 5 Service Release 4 builds to Beta directly. There will likely be one or more updates to these Beta builds before they go to Stable, so this isn’t cutting the timeframe for this release short.

As this is an earlier than normal Beta, there will probably be some issues that still need to be fixed, and others we may find as time goes on. Please use the below forum threads to report and monitor issues that may occur, and find any potential workarounds that may exist. 

** Note for Xamarin VS 2015 Users – If you installed Xamarin using our integration with Visual Studio 2015, you may be prompted to upgrade multiple times due to this release. Users installing with that method were placed on the Alpha channel by default, and we’ve made a one-time adjustment to set you back to the Stable channel. This will result in one upgrade to the new Alpha, and one update to the latest Stable release. Please feel free to select the updater channel you’d like to use, outlined in this guide.  **

UPDATED – Beta Release: Cycle 5 – Service Release 3

** UPDATE – The Xamairn.iOS build now also includes a fix for Watch Apps being rejected during app submission. **

We are releasing an updated preview of our next upcoming stable release, dubbed Cycle 5 – Service Release 3, to the Beta channel. These builds contain additional patches that were not included in the previous alphas.

This Beta release is almost ready for Stable, however we are waiting on a fix for one remaining issue, noted below. If you are encountering this issue and need to submit a Watch App immediately, we provided a download only build of Xamarin.iOS last week, based off our current Stable build to address this issue. This will be fixed for Cycle 5 Service Release 3 when it goes to Stable.

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.

Beta Release: Cycle 5 – Service Release 1

We have been hard at work on our first Service Release to address known and newly found issues with our most recent Stable products (internally referred to as Cycle 5 – Service Release 1).

We plan on doing some more internal testing of these builds, but would love for as many people as possible to grab the Beta builds and help us give them a run through.

Make sure to check out the release notes below before updating to get an idea of what has changed. Previously released builds are also available for installation if the beta builds do not meet your current needs (see guide here for how to do that). These older builds are noted within the respective product forum threads linked below.

If you happen to still be encountering any issues we believed to be fixed, are seeing new and errant behavior, or are otherwise having problems with products from this release, please be sure to post to the related product threads on our Forums. Our Support team uses these release threads, and will be communicating through them to help triage issues and supply in progress builds not yet in preview channels that may contain additional fixes.
