kapsloki Godot does have support to compile to iOS on Linux with DarlingHQ? DarlingHQ is a WineHQ clone but for MacOSX and it can run XCode without GUI https://wiki.darlinghq.org/build_instructions https://github.com/darlinghq/darling
Calinou Cross-compiling iOS export templates from Linux doesn't require a full Darling installation, only darling-dmg. See Cross-compiling for iOS from Linux. However, the documentation may be out of date as this method is rarely used in production.
