Forking transformation-ui-ios to add more image processing features

[El-Moatasem-Turing]

I am trying to fork transformation-ui-ios when adding it to the xcode it retrieves the original version not the forked ones that i can edit the SPM repo url always refer to the original repo not the forked repo

I am just asking as I am developing app involving image editing
I will definitely buy license for using the app but Is there any way i can edit the swift package manager to extend its functionalities
as the library is stable and well implemented

Thanks
