Xamarin.iOS 11.4 Release Notes

Requirements

  • Xcode 9.1 and the bundled iOS, tvOS and watchOS SDKs. Using an older Xcode version is possible, but some features are not available, in particular:

    • The static registrar requires Xcode 9.1 headers files to build applications, leading to MT0091 or MT4109 errors;
    • Bitcode builds (for tvOS and watchOS) can fail submission to the App Store unless an Xcode 9 toolchain is used;

  • Apple Xcode 9.1 requires a Mac running macOS 10.12 (Sierra) or newer;

What's New

This release is built upon our open sourced SDK, using the d15-5 branch and is based on Mono 5.4 (2017-06).
