How to open .MOC files on iOS
To open .MOC files on iOS, there is no common iOS workflow for Qt .moc files; try opening it as plain text in a text-viewer/editor app, or transfer it to a desktop editor/IDE for proper viewing.
Step-by-step instructions

Common issues
It opens as garbled text or with the wrong app
.moc files are usually generated C++ source, so opening them in a document viewer (word processor/PDF viewer) won’t work properly.
- Open the file with a plain-text code editor (not a document viewer).
- If your system keeps choosing the wrong app, use “Open with” and set a new default for .moc if appropriate.
Build errors after editing or moving a .moc file
In Qt workflows, .moc files are often generated artifacts; editing them or moving them can break the build because the build system expects to regenerate them or include them from specific paths.
- Avoid manual edits; instead, change the original Qt class header/source that triggers moc generation and rebuild.
- Clean and rebuild the project so the moc output is regenerated in the correct location.
Linux desktop doesn’t recognize the file type
MIME/extension mappings vary by desktop; your system may not have a specific association for .moc even though it is plain text.
- Open it directly from within a text editor (File → Open).
- If needed, update your file association so .moc opens in your preferred editor.
Security note
.moc files are typically plain-text C++ source code, but treat them as untrusted input if they come from unknown sources—malicious content can target editor/IDE features or confuse build scripts if you compile it.
