I've built a couple dozen projects in Xcode and only one of them experiences this strange issue.
Every time I load Xcode to resume work on the project, Xcode auto-loads the project (good) but in an unusable state (bad). It appears this way:
The project name is grayed out, with no disclosure triangle. I cannot access any of its contents, and trying to build it fails immediately with no error message other than "Build Word Practice: Failed" as you see in the screenshot.
But if I close the project and reload it, it functions fine. The only oddity about when it loads this way is that it appears with all its disclosure triangles closed, and I have to manually "disclose" the contents of all the folders in the list each time:
I have had this issue with all recent versions of Xcode, up to and including the current version, 11.5.
The project does not use any features that are not present in other similar projects I've written that behave fine. So it would seem to be a matter of corruption… but besides deleting derived data and doing a clean build (which I've done), I can't think of any other steps to take.
I would include code here, but short of including the whole project (and I doubt that would help), I wouldn't know what to include.
Any ideas?
I have an Xcode project using Xcode 8. I am using Swift if that helps/matters.
A few days ago after really not changing that much except a few funcs in one VC I tried to rerun my app and it had an error (I can't remember what it said unfortunately...but when I google'd it said basically that there was a file missing)
I located what the files were and just copied all changes into a blank project and deleted the file and pulled from Github a clean version and re adde the few funcs I added.
Everything was great and nice, until yesterday I noticed 2 yellow warnings.
I clicked the "Issue Navigator" and it is saying
TestApp project missing file
TestApp.debug.xcconfig is missing
Pods project missing file
pods - TestAPP.debug.xcconfig is missing
I realize that files just don't randomly disappear, but honestly I did not touch anything other than the Storyboard and the one ViewController File I am working on.
Why does Xcode keep deleting my files?
Is this project savable or do I need to start it over (is it corrupt?)
My project also is using Firebase.
xcconfig files are used to separate out build configuration information. Those errors are showing that you're missing entries corresponding to a debug build.
Nothing should be touching them. Only three possibilities come to mind:
You didn't create debug configs in the first place, but have tried to use them somehow.
Your path configurations are placing these in a directory that's getting wiped out when you clean/rebuild your app.
The project directory is under git control and you're doing something with git that removes the files.
Here's a screenshot showing I have two configs under my Pods project, one for "release" and one for "debug".
You might try setting up your project and making sure you see the debug configs listed. If so, see where they're kept and so on to diagnose what's going on. Otherwise, you just haven't created them.
My guess is that the files are not actually missing in any serious way. It's a bug related to use of git (as you say, the files came thru GitHub, so we know the project is tracked thru a git repository). The files were removed, but this is in fact not a problem. If that's right, then, as I explain at https://stackoverflow.com/a/39715083/341994, you can solve this simply by doing a git add or git commit of these files. That will cause Xcode to become happy and the warnings will go away.
I am using RealmSwift in my project. I followed all the instructions while setting up Realm for my project, like dragging the frameworks into the embedded binaries section, setting up the framework search path and including the required Run script in Build Settings. The project works fine after that. Then while committing the changes, I committed the header files and bcsymbol files etc of the included Realm frameworks.
After that, I took a checkout of my project. After the checkout, on opening the project, I am getting this error: 'No such module RealmSwift'.
I tried deleting the frameworks and adding them again, and cleaning the project. The project just won't compile. It keeps giving the same error. What am I doing wrong?
Hmm, there's no real good answer for solving this sort of problem, as it can happen for a variety of reasons.
More often than not, like in this SO question, it can be caused by the Framework Header Search not being set up correctly, and so the project isn't able to see the framework correctly.
If worse comes to worse, make sure to absolutely delete every reference of RealmSwift in your project (Including in the build settings) and try installing it from scratch again. Good luck!
I have a curios issue.
I have a project that I've worked on and always built from the XCode IDE, and it worked fine. Now I'm setting up Bamboo to build the project and as such am building it from the command line.
The issue is, if I check my code out of GIT and then use xcodebuild to build it it says that the scheme cannot be found, but if I open the project, it builds and if I then try to build it again from the command line with the same command, it works.
What magic is XCode doing when I open the project or am I doing something dumb, maybe excluding a file in my .gitignore that I shouldn't?
You are definitely on the right track with respect to the .xcscheme file -- I had this problem appear while setting up my own projects!
For posterity, or at least anyone getting here from a search, here are two versions of things -- the "I'm busy, so just the facts please" version and a more involved discussion and rationale. Both of these versions assume you are trying to build from a Workspace file; if you aren't then my apologies as this mostly applicable to workspace-based projects.
Condensed 'Fix-it' Version
The root cause is that the default behavior of Schemes is to keep schemes 'private' until they are specifically marked as shared. In the case of a command-line initiated build, the Xcode UI never runs and the xcoderun tool doesn't have its own cache of Schemes to work with. The goal is to generate, share, and commit the scheme you want Bamboo to run:
On a clean working copy of the code, open your Project's workspace.
Choose Scheme > Manage Schemes... from the Product Menu.
The list of Schemes defined for the project appears.
Locate the Scheme Bamboo is trying to run
Ensure the 'Shared' box is checked for that scheme and that the 'Container' setting is set to the Workspace and not the project file itself.
Click 'OK' to dismiss the Manage Schemes sheet.
A new .xcscheme file has been created in your project at WorkspaceName.xcworkspace/xcshareddata/xcschemes.
Commit this file to your repository and run a Bamboo build.
Deeper Discussion and Rationale
Xcode 4 introduced Workspaces and Schemes as a way to help try and tame some of the chaos that is inherent to dealing with the mechanics of wiring related Xcode projects, build targets, and build configurations together. The workspace itself has its own set of configuration data that describes each of the smaller 'boxes' of data it contains and acts as a skeleton for attaching .xcodeproj files and a set of shared configuration data that gets mirrored to each developer machine or CI system. This is both the power and pitfall of Workspaces -- there are 1) lots of ways in which one can get things configured 100% correctly, but put into the wrong container or 2) put into the correct container, but configured improperly thus rendering data inaccessible by other parts of the system!
The default behavior of Xcode 4 schemes is to automatically generate new schemes as projects are added to the Workspace file. Those of you that have added several .xcodeproj files may have noticed that your scheme list quickly becomes unruly especially as project files are added, then removed, and then readded to the same workspace. All schemes, autogenerated or manually created, default to being 'private' schemes visible only to the current user even when .xcuserdata files are committed with the project's data and configuration. This is the root cause of that cryptic build error Bamboo reports from xcodebuild -- Because Bamboo operates the build through the command line and not the Xcode UI, it doesn't have an opportunity for Schemes to get automatically generated and relies only on those that are defined in the workspace itself. Assuming you've configured Bamboo to build from a workspace using a command like this:
xcodebuild -workspace MyWorkspace.xcworkspace -scheme MyApplication -configuration Debug
xcodebuild goes looking for file <'scheme' Parameter Value>.xcscheme existing at <'workspace' Parameter Value>/xcshareddata/xcschemes.
Obviously there are bunches of ways in which one could configure both Bamboo and a workspace, so keep in mind that your unique configuration may not map 100% to what is presented here. The key takeaways:
Certain automated tasks the Xcode UI magically takes care of are not available via the Xcodebuild CLI.
You can attach scheme and build configuration data to many places in the 'container hierarchy' -- Make sure your data winds up in the right container (Workspace, Project, and/or Build Target)
Consider where in the container hierarchy the xcodebuild tool may be looking for configuration data; a great indicator of where it will start looking is based on the use of '-workspace' or '-project' arguments.
The 'Shared' box is already checked...now what?
I encountered this same issue on my own Bamboo instance; it turned out that the scheme that was committed in my repository was outdated and the latest version of the command line tools wasn't handling it gracefully. Since this existed previously, I took a look through the settings to make sure there wasn't anything glaringly custom about the scheme, deleted and recreated the scheme ensuring that I marked it as 'Shared', and recommitting the new .xcscheme file to the repository.
If everything looks good and rebuilding it doesn't solve the issue, double check that container setting -- it is really easy to get that scheme attached to the wrong container in the hierarchy!
Debug the issue like this:
xcodebuild -list
or if you are using a workspace (e.g. with pods)
xcodebuild -workspace MyProject.xcworkspace -list
If you scheme is not listed fix like so:
Most of the answers would suggest you to make your scheme shared using Xcode, then commit changes to repo. That works, of course, but only if you have access to source code and have rights to commit changes, and couple of other assumptions.
But there's a number of "what ifs" to consider
What if you just can't modify the Xcode project for some reason?
What if you create a new scheme automatically on CI server? This actually happens quite often. If you use test automation framework, like Calabash, you'll normally end up duplicating an existing target, which automatically duplicates a scheme as well, and the new scheme is not shared, even if the original scheme was.
Ruby & xcodeproj gem
I would recommend using xcodeproj Ruby gem.
This is a really cool open source tool that can help you to automate tons of Xcode-related tasks.
Btw, this is the gem used by CocoaPods to mess around with your Xcode projects and workspaces.
So install it
sudo gem install xcodeproj
Then write a simple Ruby script to re-share all the schemes, the gem has recreate_user_schemes method for that purpose
#!/usr/bin/env ruby
require 'xcodeproj'
xcproj = Xcodeproj::Project.open("MyProject.xcodeproj")
xcproj.recreate_user_schemes
xcproj.save
It doesn't just copy scheme files form user's folder to xcshareddata/xcschemes, it also creates those files first by parsing the pbxproj file.
Ok I know its 2 minutes later but I found another stack overflow that says the scheme has to be set to shared... Where does Xcode 4 store Scheme Data?
One common reason for the scheme to be missing is forgetting to push the commits to the origin. If you get a missing scheme message, you should first verify the scheme is shared, then verify you have committed the changes AND pushed them to the origin server.
I had this error while implementing CI.The Question above is identical to my problems except I am using Gitlab's own CI tool.You can check if there is any such file in Bamboo.
I solved it by making some changes to gitlab-ci.yml file.
After you hav made your scheme availabe by sharing. In Xcode Go to Products>Scheme>Manage Scheme and check share to share.
Changes
Set absolute path everywhere.
eg.xcodebuild clean archive -archivePath /path/to/your/project/build/testDemo -scheme testDemo | xcpretty
here you need to change /path/to/your/project/ with your path and testDemo with your project name.
I faced this issue and even if some of the answers here actually provide the solution, I didn't find it very clear. So I will just add one more. In a nutshell how to share a schema from excode.
Navigate to Product > Scheme > Manage Schemes
You will then be shown a list of schemes, with each denoted as being shared or not. Just check the ones that you want to share (it may be different ones for dev and prod builds)

Got the same problem but during building with xcode as subproject of main one. Built subproject in xcode standalone - after that this error disappeared.
I want to add solution for my case related to this thread. This one is for you who clone existing project, with all the schemes you need are already being shared:
, with fastlane lanes correctly display all your lanes including all your schemes:
, but fastlane gym only show main schemes (not dev and test schemes):
The solution is to uncheck the shared option for schemes that not listed by fastlane gym and then check it again. It will generates .xcscheme for the schemes:
Now, if you check with fastlane gym, all the schemes will be listed:
Then you should commit those .xcshemes file to the repository, so other developer who clone the project will get the files.
For anyone with Xcode 11.4 trying to find "Shared" button on scheme, it's now moved into the individual scheme.
Select the scheme you want
Press "Edit"
Check the "Shared" box
I am currently working on a project which runs just fine in both the simulator and on device except for one particular method which does not update on the device or in the simulator. It seams that I can put whatever I like in it and it just runs an old version. If I change other methods in the same file they build and run with the changes. Any ideas why this is happening or what I could do to solve it?
One suggestion I heard was to start a new project and copy my code in. I would like to avoid that if possible but it looks like I might have to.
Sometimes you need to do a clean build because Xcode does not always notice dependency changes (e.g. changes to source files).
Some people do not configure their dependencies (e.g. static/dynamic libraries) correctly. If you are using the auto-detect-dependency feature, it still has some bugs, so you may need to configure this explicitly.
FWIW, starting a new project has never been necessary for me...
