Today I checked out a new copy of stable project from gitHub to my home computer using Xcode 6.1. After doing so, I see that many of the frameworks and libraries, including XCTest, are missing (shown in red). I have added Framework and Header Search Paths, but they are still not found.
To make things stranger, I can build the project to a simulator or device, but when I try to run an individual test, I get clang or missing file error for the libraries/frameworks shown in red.
As it turns out, the reason for my errors was that I had not run "Build for Testing" before trying to run the individual Unit Tests. As such, the proper library dependencies had not been generated.

After updating to Xcode 12.2, my project started failing to compile because of Apple Silicon-related linking errors. I seem to have most of them fixed, but one sub-project that builds a statically-linked framework is giving me problems. And yet a sibling sub-project with apparently identical build settings doesn't.
During linking, I get this warning about the one framework:
ld: warning: ignoring file ...Build/Products/Debug-maccatalyst/TCSiOSC.framework/TCSiOSC, building for Mac Catalyst-x86_64 but attempting to link with file built for Mac Catalyst-arm64
I'm building on an Intel Mac, to boot (so "build active architecture only" is not a factor). I can't find any build setting that would address this problem, and a Web search turns up no hits on this exact error. Any ideas appreciated!
I consulted Apple for this one, and their engineer recommended some things:
Turn any Swift sub-projects into Swift packages, not embedded Xcode projects. So, I deleted one library's Xcode project from the parent project, and dragged its top-level directory into the parent project to include it as a Swift package. Now... this particular sub-project (SQLite.swift) already had a Swift package defined. I haven't generated a Swift package myself before, so I can't help with that. Also, don’t forget to add it to the Frameworks, Libraries, and Embedded Content list on the app’s target.
Go into your project's build settings and delete the "Supported platforms" setting. If you click on the "levels" button above the build-settings list, you can see where each setting is coming from. "Supported platforms" should be non-bold. Highlight the line and press Delete if it's bold. Then go into your target and do the same thing: delete "Supported platforms."
Set the Base SDK at your project (top) level to iOS; this is a must. Delete it from the target level, so it inherits from the project; I don't know if this holds true for multiple kinds of targets or all projects, but it's working for me.
Remove the VALID_ARCHS build setting from all targets, if it's present. That setting is deprecated.
The "build active architecture" setting doesn't make any difference after these changes in my case. The project now builds and runs under Catalyst just fine.
I have the same issue and found this question. In my case, building on Debug succeeds but on Release fails. The reason is exactly the "build active architecture only" option. It is an option can be found in your PROJECT - "Build Setting" Tab then "Architectures" section. There is a setting for "Build active architecture only". By default, the Debug mode it is Yes while Release mode it is no. That caused my build to fail in release.
I've got a phonegap project that is getting built via Jenkins via the Xcode plugin. After the project is built, I'm using the TestFlight plugin to upload it there. Everything works great.
Now, I need to add two more versions of this for our different environments so I'll have a Dev and Test version (and also Prod, but not to TestFlight).
In order to do this, I need to change the name of the application so both Dev and Test show up in TestFlight, MyProgram-Dev, and MyProgram-Test. Then the production version would just be MyProgram.
In the xcode section on Jenkins, there's a "custom xcodebuild arguments" field that can be filled out, which I'm assuming is where I need to make my changes. I want to do this at build time because I don't want the program name to change when merging Dev into Test, etc.
I've done alot of googling and can't find any example command line parameters for the xcode build process. Is it the CFBundle that I need to be changing? What is the name of the parameter to change?
Edit: So I was able to change the production name via 'PRODUCT_NAME=MyProject-Test', but that produced the following error:
The following build commands failed:
Ld /Users/buildaccount/Library/Developer/Xcode/DerivedData/MyProject-cpvmaiwadviebmbhkdggxpzejddf/Build/Intermediates/MyProject.build/Release-iphoneos/MyProject.build/Objects-normal/armv7/MyProject-Test normal armv7
Wow, that took alot of googling and testing.
Here's what was the eventual fix for my scenario. It was a combination of this post/answer, as well as this one.
I've got a workspace containing an iOS app project, which is dependent on another framework project, also in the workspace. I ran into issues with Archive while building for distribution, where the resulting output was unusable for creating an .ipa. Googling turned up this solution, where you delete the Copy Headers phase from the framework project, and which worked for getting the Archive exported and submitted, but now when I go back to running the app project in debug, I'm failing builds due to missing header files from the framework project again. So, what is the proper way to configure everything so I can both archive and run in debug without having to go through all this nonsense? I mean really, I'd think this would be pretty typical.
I ended up replacing the previously deleted Copy Headers phase within the framework project, with a Copy Files phase, and that did the trick.
I've setup cocoapods for my project and I've been doing development for quite some time without any issues. Recently I added a new Configuration for it called "Beta", duplicating the "Release" configuration. At the same time, I added a Scheme that would build targets using this configuration.
This new scheme would build everything without issues, but linking would fail with the (quite known it seems) message:
ld: library not found for -lPods
I know that issues that makes this error message come up have been discussed widely around the web, with different causes and conditions:
library not found for -lPods
https://github.com/CocoaPods/CocoaPods/issues/155
None of these fixes seem to apply here. What I can see by looking into the workspace folder, is that Cocoapods build products are put in Build/Products/Release-iphonesimulator instead of in Build/Products/Beta-iphonesimulator, even though the app itself is built rightly so into the latter. Moving all the *.a files into Build/Products/Beta-iphonesimulator makes running in the simulator work properly, but the next build is still put in the wrong location.
Edit
After some further investigations, the environment variable $BUILT_PRODUCTS_DIR is set correctly in the build phase for the app itself, but not when building cocoapods products.
What causes this and how can I fix this?
Ruled out issues
pod install has been run, multiple times
I'm working in the workspace, not in the project
The cocoapods configuration file in the new configuration is properly set
Build locations in the preferences seem fine
For the record, the issue has been solved. So, as I said, I use cocoapods, but my current setup is that a single podfile, and workspace is used for 3 projects that share some common libraries. As explained in this issue, cocoapods will only consider one project out of all those that are specified in the podfile, and it turns the one project (out of three) that it was using, didn't have the beta configuration, so it didn't feel the need to prepare for it. So when it was time to build the project with the beta configuration, cocoapods would be built for the release configuration, and put in some folder specific to release, so the beta project wouldn't be able to find it.
Fixing was a matter of creating the beta configuration for all projects present in the workspace, forcing cocoapods to prepare accordingly. Then, Xcode would be able to wire up everything appropriately.
I'm working on an iOS app project, and add the json-framework project to the workspace. The project navigator on the left shows both projects, and the build scheme selector shows the schemes from both projects too. Now I want to add the libjson.a target from the json-framework project as a dependency on the iOS app target in the other project. The expected result is that whenever the app target is built, it builds (if necessary) the library target and links the app target against it. Here are the ways I've tried to do this:
Build both as part of the same scheme. The way I try this is to edit the scheme for my app, adding 'libjson.a' to the 'Build' portion of the scheme, and by the way "Find Implicit Dependencies" is checked. Then I go to the target editor for my app target, and in "Build Phases"->"Link Binary With Libraries", I choose 'libjson.a' from the list of workspace libraries.
When I subsequently try to build the scheme, I see it build the library target, but building the app target fails with linker error "Library not found for -ljson" - suggesting that it hasn't actually discovered that the library has been built. Indeed in the project navigator, the entry under the app project for the library is still red indicating that the file doesn't exist.
Add the json target as an explicit dependency. To try this, I don't modify the build scheme, but go to the target editor for my app target and click the add button under 'Target Dependencies'. No targets from other projects in the workspace show up, so this is a non-starter.
Drag the JSON project into the other project, then add the target as a dependency. This is what I would have done in Xcode 3. In the project navigator, I grab the library project and drag it over the app project. This brings up the usual 'add files' pane, which I just dismiss by clicking 'Finish'.
There are now two entries for the library project in the project navigator: one at the top level, and one under the app project. I can now add the library target as a dependency of the app target using the target editor, and can link against it without error in the link libraries phase. But it looks broken: there are multiple entries for the same project in the navigator. Is there a different way to do this?
What should be considered the "Xcode 4-ish" way of connecting these targets in different projects in the same workspace? It would seem lacking if multiple projects in the same workspace can't actually interact with each other.
Thanks,
Graham.
I’ve just set a test project up, pretty much as you describe in version 3, by creating a new workspace and dragging the two Xcode project into it, nested as shown.
You can delete the sibling project if you have it already.
Hitting build on this and it just works, as far as I can see.
I imagine there is internal path-confusion if you have two projects, and I’d be inclined to fiddle with location settings in "View"->"Utilities"->"File Inspector" and see what effect that has.
Another thing to try is to set your paths up in Xcode "Preferences…"->"Source Trees" and refer to them that way, as described here: Easy, Modular Code Sharing Across iPhone Apps: Static Libraries and Cross-Project References

I managed to get dependencies between projects in a workspace to work as I described here: http://blog.carbonfive.com/2011/04/04/using-open-source-static-libraries-in-xcode-4/.
Unfortunately I can't find a way to get Xcode to discover implicit dependencies or index everything in the build as advertised. I found workaround to both but I'm hoping that less manual configuration will be needed as Xcode 4 matures.
I was going to ask the same question, thinking that my own solution couldn't be right. But I don't see it mentioned here, and it does seem to work. Clearly XCode 4 is a work in progress. :)
I have a workspace with two projects: a static library and an app which uses the library. The projects are siblings. Each project has its own scheme, and each scheme is set to only build one target. In other words, I added two projects to the workspace and that's it.
To add the static library as a dependency of the app, I just drag the libsomething.a product from the library project (Project Navigator) into the "Link Binary with Libraries" list for the app target. That's it. Now when I build the app the library project is built first and then linked. Interestingly, when I modify the app's scheme to use a different configuration (eg, Release instead of Debug), the library is built using the same configuration.
So it works, and there is clearly some automatic dependency checking going on here. But it feels wrong. Then again, so does the modal scheme editor/manager and lack of a workspace object in the project navigator... I never thought I'd say it, but the Visual Studio UI (bleh) is a lot clearer.
My bullet-proof solution to do this :
Create "Per Debug-Release / Per Architecture" settings in Build Settings in the Main project (not the lib), to include either
../MyLibProject/build/Debug-iphoneos
or
../MyLibProject/build/Release-iphonesimulator
or
etc..
depending on the configuration (you can create those kind of configuration by clicking on the + next to Debug or Release and choose either "Any iOS Simulator SDK" or "any iOS SDK".
You need to do that for both "Header Search Path" (in case your library copy some headers files, which is more than likely) AND for "Library Search Paths". Which means that for each setting, you'll probably end-up with 4 different paths (debug sim , debug ios, release sim, release ios).
That would make sure the configuration of both projects match.
Now, to auto-compile the lib, that is to create the dependency, you can use the "Build Phase -> Link to Binary With Libraries -> + -> select the .a file" advice given above.
That's the only way I managed to have something that builds and link correctly for every environment on xcode 4.5
Note : I even added the -lmyLib flag in "other linker flags", but i'm not sure that's really necessary
I've had some success with creating framework-like static libraries, though it's not a perfect solution.
I see the next variants:
Explicit dependency in a project[About]
Implicit dependency in a workspace[About]
See the Xcode user guide: Xcode Concepts -> Xcode workspace under 'Projects in a Workspace Share a Build Directory'.
All projects in a single workspace share a build directory. Dependencies are discovered automatically and build if needed:
"Xcode examines the files in the build directory to discover implicit dependencies. For example, if one project included in a workspace builds a library that is linked against by another project in the same workspace, Xcode automatically builds the library before building the other project, even if the build configuration does not make this dependency explicit. You can override such implicit dependencies with explicit build settings if necessary. For explicit dependencies, you must create project references."
