Swift Xcode中的文件有问号（？）

Question

I am working with Xcode for 3 months now. This has happened to me twice.

Xcode deleted my ViewController.swift file twice. I couldn't find it in the bin. I dont know whats wrong with that.

App was working nice then I commit my code. After that, Xcode gives me compile error:

File "myController.swift" not found

Xcode showing "?" at front of my swift file:

Answer 1

The question mark means that the file is not under version control, it doesn't mean that it has been deleted. You can use the command git add -A to add all files in the directory to your version control. This SO question lists all the Xcode version control symbols, here they are.

U: Working file was updated

G: Changes on the repo were automatically merged into the working copy

M: Working copy is modified

C: This file conflicts with the version in the repo

?: This file is not under version control

:: This file is under version control but is missing or incomplete

A: This file will be added to version control (after commit)

A+: This file will be moved (after commit)

D: This file will be deleted (after commit)

S: This signifies that the file or directory has been switched from the path of the rest of the working copy (using svn switch) to a branch

I: Ignored

X: External definition

~: Type changed

R: Item has been replaced in your working copy. This means the file was scheduled for deletion, and then a new file with the same name was scheduled for addition in its place.

L: Item is locked

E: Item existed, as it would have been created, by an svn update.

Answer 2

This could be due to the git/source tree when your code is under version control. when you import files to your project and this will not be added in git.

To fix this:

right-click on the '?' file and select source control then at the bottom click Add Selected Files . This should fix.
