Swift versions prior to 5.1 do not support module stability and require the frameworks to be build with the same swift version as the current development environment. There is a command line option in carthage called --toolchain which can be used to change the toolchain used to build the frameworks. This pull request adds the support into accio to pass that parameter to carthage while building.
