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
orMT4109
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.
Open Source
Xamarin.iOS is based on the following open-source repositories:
- xamarin-macios branch
