This can happen on the Demo App: FerrostarCoreFFI/ferrostar.swift:518: Fatal error: 'try!' expression unexpectedly raised an error: FerrostarCoreFFI.(unknown context at $1029b9d94).UniffiInternalError.bufferOverflow

Hey, good question ;) this actually happens only when there is a mismatch between the Rust code and the Swift bindings. It looks like we are in that state right now as we are between releases. We have release automation planned but until then it's a manual process.

After deleting the Xcode and Rust cache many times, I finally found the cause of the problem: After I pulled the latest code, useLocalFramework in Package.swift was reset to false and I didn't notice. That explains why build-ios.sh doesn't work in the case and it made me think there was a problem with the code. Sorry for the confusion!
