Hello, @izmcm ! It looks like you may have included some of your own local config (e.g. .idea, gradle.properties, perhaps more) in this PR. Can you take a look and clean it up, please?

extension.properties:6

• extension.properties looks like extension metadata that ships with the plugin. Adding a machine-specific absolute GHIDRA_INSTALL_DIR path here can leak local paths and is likely ignored by Gradle (which reads env vars / Gradle properties), while potentially confusing users. Please remove this from the shipped properties and rely on GHIDRA_INSTALL_DIR env var / gradle.properties as documented in build.gradle.kts.

@nmggithub I believe I did all the changes you and Copilot requested. I also added a new analyzer that decoded small Swift strings. Let me know if there is anything I can make :)

I'll take a look when I can. I really do appreciate the effort you put into this!
