Breaking Changes

Integrated Mono Features/Fixes

Xamarin.iOS uses a customized runtime and base class librairies (BCL) from Mono 5.11 (hash).

Additional information can be found in Mono release notes.

What's New in this Release

• Xamarin.Analysis Use LLVM rule

This release is built upon our open sourced SDK and offers the following new features:

• Existing bindings for vImage (Accelerate) are now enabled for watchOS

Xamarin.Analysis Use LLVM rule

We added a new rule to our project analysis tool which recommends enabling the LLVM compiler for Release|iPhone configuration. LLVM generates code that is faster to execute at the expense of build time.

As a reminder to run the rules, in Visual Studio for Mac's menu, select Project > Run Code Analysis.

Note: all existing rules are documented here.

Known Issues

Using an older Xcode version

Using an older Xcode version (than the one mentioned in the above requirements) is often possible, but some features may not be available. Also some limitations might requires workarounds, e.g.:

• The static registrar requires Xcode headers files to build applications, leading to MT0091 or MT4109 errors if API are missing. In most cases enabling the managed linker will help (by removing the API).
• Bitcode builds (for tvOS and watchOS) can fail submission to the App Store unless an Xcode 9.0+ toolchain is used.

API Diff

This is a live document so there's no static list to link to. However our Jenkins bots produce this information for every commit that is being built. Pick a build based on master and look for the API diff link on the left column.

Open Source

Xamarin.iOS is based on the following open-source repositories:

• xamarin-macios branch master
