Tried this again when switching back to v12 – and ran into the same compilation issue. Issue is not that skiaSharp v12.2.1 is missing – it is present. Issue is that it is looking for the wrong version of skiaSharp – its looking for version 1.68.0.0 as noted in the first message. This problem only occurs when building for release and not debug. Basically the “link Framework Sdks Only” option vs “Don’t link” under the build options. As noted above directly linking that version of SkiaSharp gets past this issue and things appear to work correctly but having multiple references to different versions of the same package is likely problematic. Can be duplicated by using code included here [https://community.thinkgeo.com/t/requestdrawing-not-redrawing-layer/9886](https://community.thinkgeo.com/t/requestdrawing-not-redrawing-layer/9886) Also can be done with the new howdoIsample for the forms implementation --- _[View the full topic](https://community.thinkgeo.com/t/linking-error-when-buildig-for-ios-release/9869)._
