Why xcode can't see these files, however they physically exist

Question

Xcode run into compilation error while running the code.

Unfortunatetly I was not able to find a solution online.

These steps that I have commenced:

=> git merge branch-name => can't find the files => git checkout branch-name file-name => files were physically found => xcode can't see it

???

Answer 1

You have to add them to your project at File -> Add Files To "Your Project"

btw: Your project folder in Xcode does not necessarily reflect your actual folder structure you see in finder.

Edit:

if you want it to be like that (Xcode folders are the same as the existing folders in your harddrive) I found a nice tool which does that for you: https://github.com/venmo/synx

also, when creating new folders/groups in Xcode, you have to use the New Group with Folder option to also create a folder for that group on your harddrive.

Answer 2

Tested in xcode 11

You have to add them to your project by pressing right-click on the app folder Add files to "app"... select all the missing and NEEDED files, click on create groups option and press finish.
