Hey there, many thanks for your time! Goal: Using lib_InternalSyntaxParser.dylib in an app-store compatible build for iOS. Some quick context: swift-syntax Library repo - https://github.com/apple/swift-syntax My reference project - https://github.com/tikimcfee/LookAtThat Updated / standard instructions on manually building dylib - https://github.com/pol-piella/polpiella.dev/blob/4a7b5f6e6b3511d5010da887435f870f84c53d2a/src/pages/embedding-a-dylib-in-a-swift-package.md Issues: x86_64, arm64, iossim all require different architecture builds of lib_InternalSyntaxParser. I cannot embed the dylib generated by the build tool into a app-store capable build (not supported by iOS). macOS dylib with an exported .app is fine so far. Attempting to wrap this with a framework causes signing errors after installation on device. Question: I am looking for guidance on the proper, expected practice for bundling the multiple versions of this dylib (listed above). I was fortunate enough to meet one @Rintaro (hello and thank you again!) at this year's WWDC developer event, and they suggested I pop up my issue here. I am happy to answer questions to help narrow down a solution! I would greatly appreciate an as-detailed-as-is-reasonable explanation of what the expected process of embedding this dylib looks like, and what the specific requirements are for code signature and verification for this use case. A third and final time: many thanks for your time, patience, and assistance.
