Integrated Mono Features/Fixes

Xamarin.iOS uses a customized runtime and base class libraries (BCL) from Mono.

Additional information can be found in Mono release notes.

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.
