I want to add a file to an existing folder in Xcode. I have a folder in the file system that I have added to my resources. Now when I add a file to that folder, and try to drag and drop that file onto the folder reference in Xcode, I am out of luck.
Even if I delete the reference and drag the whole folder over again, it does not work, as it imports all files that were in the folder when I originally imported it, but not the new ones.
Any ideas on that one?
Drag it into that folder in Finder, then right click that blue folder in Xcode and then "touch" it. Or collapse and expand that folder icon (is like touching it).

I'm curious when using Xcode.
I always need to choose an option when copying the open source class files I need for my project.
The options are "Create groups" and "Create folder references".
I've read the difference between the two already.
But it is not understood at all.
When I chose one of the two options, I deleted the file from my project and the open source class file was deleted at the same time.
I do not want it.
I want to always exist as an independent file. What should I choose?
It took me a while to understand the difference between those two options so I thought I'd share:
I'm writing this when Xcode 12 is the current version
The biggest difference is how the imported folder / file will be accessible from the finder. Let's say you want to import a new folder to your Xcode project. When you choose Create groups Xcode will import your new folder and create a group (the yellow icon). When you go to your project's directory (using Finder) you should see a folder named like the one you've just imported, but any additional files you put to this folder trough Finder won't be visible in your Xcode project.
When you choose Create folder references the imported folder will have a classic blue folder icon in Xcode. This new folder will also be visible when you go to your projects directory, but now every new file you put there will also appear in your Xcode project.
If you want to know more just read this explanation http://www.thomashanning.com/xcode-groups-folder-references/
It's pretty straightforward and easy to understand.
There are two types of any Xcode project structure organization:
filesystem project structure (inspectable with Finder.app)
IDE project structure (inspectable with Project Navigator in Xcode's navigator area.)
Xcode relies on filesystem organization by keeping a reference to a "physical" file or folder. That is why you may have all the classes, images, plists, and other parts of your projects stored in the same folder, while the references to these parts are being kept organized into respective groups within Xcode project.
When you create a group, it affects the organization of your project in Xcode. When you create a group with a reference folder, it creates both, a group in Xcode project and a folder in your filesystem.
However, since Xcode 9 it seems like, Apple enforces filesystem project structure to correspond to Xcode project structure. It means, that you explicitly has to choose "New Group without Folder"
Added files and folders from Finder into the Xcode group. Xcode 10.2.1. Just take a look at the examples without Copy items if needed
Files
Common behaviour for create groups and create folder references
Rename a file from Finder does not rename the file in Xcode, as a result Xcode doesn't handle it and it will mark them by red color.
Rename a file from Xcode rename the file in Finder
Change a file from Finder change the file in Xcode and vice versa
Remove to trash a file from Xcode change the file in Finder and vice versa
Add a file from folder in Finder does not add the file to group in Xcode
Folders
Common behaviour for create groups and create folder references:
Rename a folder/group from Xcode rename the folder in Finder
create groups
If you choose create groups, then the corresponding folder appears with a yellow icon in the project navigator.
It is just a virtual folder. It useful during development when you copy a file and it is not compiled and you do not have a time to make changes in it and want only to check if a project works. So you can just remove a reference from a file. It will not be removed from a folder as a result you will be able to add this file again.
Rename a folder in Finder does not rename a name of group in Xcode. You steal can work with group but previous content inside although visible but unavailable
Add a file to a folder in Finder does not add the file to group in Xcode
Add a file to a group in Xcode does not add the file to folder in Finder
Remove a folder in Finder does not remove the group in Xcode. You steal can work with group but previous content inside although visible but unavailable
create folder references
If you are choosing create folder references, then the folder appears with a blue icon in the project navigator.
It is a real folder and any changes will be reflected
Rename a folder in Finder does not rename a name of folder in Xcode. The previous content is gone and you can not work with this folder
Add a file to a folder in Finder adds the file to folder in Xcode
Add a file to a folder in Xcode adds the file to folder in Finder
Remove a folder in Finder removes the folder in Xcode.
[Copy items if needed]
Create folder references:
Useless because even if you list this folder to be included with a target, Xcode won't include any of its contents in that target and there's no way to click on something in the folder and see which targets it's included in.
Create groups:
This is the only way to go, if you want to include any of the folders' contents in a build target.
I am using Xcode and currently my images are on desktop , what is the right way to move them in to the folder?
(when I just copy paste them my project not builds).
is there any easy way to do that without re linking the images 1 by 1 ?
1.In the Xcode project navigator, select the destination project or group for the item you want to add.
2.Choose File -> Add Files to “”.
3.Select the file or folder to add.
4.Select destination, folder, and target options, and click Add.
or
Just drag and drop your desktop folder into Xcode project.
In your case the images are on desktop. So you have to check Copy items into destination group’s folder option. Select this option to create a copy of the selected file or folder in the workspace. Do this if you want to delete, move, or rename files or folders in the workspace without altering the original versions on disk.

Situation:
In Xcode 5, you have a resource such as a nib that is not localized, and then you localize it by clicking a language Localization checkbox in the File inspector of the Utilities pane on the right hand side (see picture below).
Behavior: For me at least, Xcode creates an lproj folder at project-root/lang.lproj/ and puts the resource file in it. That is, the lproj folder is inside same parent folder as the .xcodeproj file itself.
Desired Behavior: Xcode should put the new resources into my already-existing lproj folders, which are in a subfolder or the project root. That is, project-root/resoures/lang.lproj/. It should not create a new lproj file in another location.
Is it possible to instruct Xcode to look for & create lproj folders in a different location from the folder where the .xcodeproj resides?
I want to have all my image files in a folder so that I can obtain all of them at the same time. I think the path should like this ...MyApp.app/image folder/1.png.
But when I drag them into xcode with folder references created, there is no folder. The path is always MyApp.app/1.png.
Also, I think I've dragged the files into the app several times. How to delete the files? It's not enough to just delete the references.
If they are not visible in project navigator, that means that you have no references to them and you can delete them directly in finder.
You are likely to have moved every image to a group rather than a folder. A group is just a convenience in Xcode project navigator. It has nothing to do with file hierarchy.
To keep them in a folder, right-click project navigator. Select new folder, drag your files to that folder. When they are visible in your project navigator, make sure that they are all linked to your project. I.e they are all check market with your project in the right pane.
It important to drag them to the folder and not just outside of it.
Here's the easiest way to do this in Xcode:
1)
Put all your images into a folder and then drag that folder into the list of files in your Xcode project. That step looks like this:
2)
A sheet will drop down in Xcode and ask you how you want to add these files to your project. It looks like this:
There's a checkbox at the top there that says "Copy items into destination group's folder (if needed). You will check this if you want to copy your folder full of images into the same place where your source code is found in your Xcode project.
3)
When you're done adding, here is what your project should look like in Xcode. Notice that the folder color is blue. That means it's a folder reference. This folder will be copied into your built application.
Something has become buggered with my project.
I can't delete files or rename files from Project Navigator view.
It may have something to do with source control? If I highlight 5 files in Project Navigator and hit delete and then move to trash the first file gets a source control "D" marking beside it but all of the files still remain.
Restarting mac/xcode has not resolved it. Any ideas?
Same thing happens to me for a while now.
Using git.
So far I'm able to work around this by deleting the files one at a time, which moves the file to trash but doesn't remove the reference. And then deleting the references again.
Similar problem with adding files to the project and renaming them.
For adding: first move/copy the required file in the project folder to the desired location, and then add from Xcode deselecting the "Copy items..." checkbox.
For renaming: find file in finder, rename IN FINDER, then change the name accordingly in Xcode (or choose the file again from the right panel).
Hopefully we won't have problems like these after moving to Xcode 5.
