With WINDEV MOBILE 25, in order to generate an archive without link error, the following requirements have to be satisfied:

• use WINDEV Mobile 25 version 83n or higher,
• use Xcode 11.4.1 or later,
• copy the project for Xcode to a local internal drive (no network share, usb, NAS, etc)

Even when these conditions are met, Xcode may still display linker errors. In this case you have to do the following:

• in Xcode execute the "Clean Build Folder" option,
• quit Xcode using the "Exit" option in the "Xcode" menu (don't just close Xcode by the cross),
• restart Xcode,
• reopen the project,
• run again the archive generation,

Repeat this process if Xcode still shows errors.
