Hi Nwasinachi,
As per my understanding, you want to combine several “MLAPP” files into a single “MLAPP” file, so that all your UI figures can be run with one code/ one “MLAPP” file.
Unfortunately, there is no way currently to merge “MLAPP” files, in Git or outside, aside from a very manual process of comparing the files using the Comparison Tool and then adjusting the UI elements in the Design View to match the generated (greyed out) code.
The current recommendation for making this merge process less painful is to:
1) Migrate all non-UI code from within App Designer to outside functions and classes
2) Limit changes of the UI code to one developer at a time, to minimize the number of merge conflicts in MLAPP files
Point (1) also has the benefit of making the "business logic" or "backend" code testable and runnable outside of the application.
