Get mobile sandboxed data path

[meponderR]

Looking through the code I did not see a way of getting the app's home directory path or documents, application support, cache, or temporary data folder on iOS. I also didn't see a way of getting external or internal app storage paths on Android.

From what's exposed in Wails today, there does not appear to be a dedicated mobile helper for iOS/Android app-private paths like Documents, Cache, or app files. So this looks less like a docs gap and more like currently unsupported mobile storage-path surface.

The application.Path(...) helper in Wails v3 is backed by XDG-style desktop paths such as PathDataHome, PathConfigHome, PathCacheHome, PathDocuments, and so on. The mobile-specific Android/iOS APIs expose things like secure storage, app info, storage space, camera/share/haptics, but I do not see a matching ApplicationSupportDir, iOS Documents dir, Android files dir, Android cache dir, etc.

For now I would separate the use cases:

• for normal private app data, use Go's standard library in your backend and test it on device: os.UserConfigDir(), os.UserCacheDir(), and os.TempDir();
• for secrets, use the mobile secure storage API instead of writing your own file under an app directory;
• for user-visible/import/export files, go through the platform picker/share/document flow rather than assuming a stable external-storage path, especially on Android.

If you need exact native paths such as Android Context.getFilesDir() / getCacheDir() or iOS FileManager.urls(for:in:), that looks like a small Wails mobile API gap rather than something hidden behind the existing path selector.

If this matches what you are seeing, a feature request for mobile-private/cache/documents path helpers would be the right next step.
