Often Xcode build become messy, so I frequently use Clean and re-Build my project. The project depends on several open source projects, which is managed by cocoapod.
The problem is that when I use Clean ⇧⌘K, the entire workspace is cleaned, so all of the cocoapod-dependencies are rebuilt, which takes most of the build time. But in most of the case, I just want only my own project is cleaned. How do I do this?
Go to Edit Scheme
Then click Build and untick the Find Implicit Dependencies

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 currently configure CMake/CTest for CI. Everything works fine except for the following:
We have several projects which depend on each other. In our toplevel build script, though, they are just being built in the right order. During CI, for each of the projects I just do a "make Continuous" in the build directory of the respective project. However when, say a header file is updated in one project only this project gets build after "make Continuous". Another dependent project which uses the same include files is not rebuild during "make Continuous" because in this project no updates occur.
So my question: Is there any way to force the build step to be done during "make Continuous", independent of the result of the svn update?
Any other ideas how to solve this?
add_dependencies will work for your case.
add_dependencies(target-name depend-target1 depend-target2 ...)

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."
I want to be able to build a web project and not its dependencies since I know that I have not modified any of the dependencies since the last build. I am looking to cut down the build time if possible. Is there a way to do this?
You could have a solution by
check the setting in Tools >> Options >> Projects and Solutions >>
Build and Run setting : Only build startup projects and dependencies on Run.
OR
If you want to go for sophistication then :
build >> Configuration Manager
from the "Active solution configuration:" dropdown select ""
give a name to your configuration and keep checked the "Create new project configurations" checkbox.
and then choose that config that you want and set the build or not check boxes.
To accomplish this in something I am working on, I created my own solution, added the projects I needed (including the projects I never wanted compiled), and then in the Configuration Manager turned off the check boxes for building the projects I didn't want to build, just as arora described above.
I've also made a copy of an existing solution (that had 16 components in it), saved it under new name (foo.sln -> foo.mine.sln), and then disabled the build of all the other sub-projects except the one(s) I am working on, that way I know for sure that I got the correct build settings.
It's not the simplest solution, but it works well for me, and takes less than 2 minutes to set up and is easy to understand. I normally add the new solution to the version control ignore list so that it never gets checked in.
Rather than project references you can just add the references to the dlls directly (the Add Reference dialog has tabs for these types, choose browse rather than project and remove the other projects from your solution). I typically create a full lib and web project solution for major development. Then just a solution for the website project for fixes where I don't need updated libs/dlls.
Although it is nice to have them autocompile if they have changed during heavy development. If they haven't changed it just refreshes them and recopies them to the bin folder.
Well one way would be to remove project references. Instead stick to dll references. You could use a post build script for dependent projects that copy the updated dll to the web project whenever they change.
I have an Xcode project (A) referencing another project (B). By default (as far as I understand it) Xcode will implicitly build the configuration for the B dependency that matches the configuration of the A's target (e.g., "Debug"). But what if I want, say, A to build as "Debug" and the B to build as "Release"? How would I go about specifying that in Xcode?
I don't know of any easy approach, but you can brute-force it by calling xcodebuild directly for the dependency with a "Run Script" build phase.
I know it was just an example, but if your real goal is that the sub-project be a Release (no symbols) build, then you may have a better experience by just building the sub-project into a library or framework and checking the resulting binary into your version control system. Whenever I have a piece of the system that seldom changes and that I don't want debug symbols for, I go ahead and build it as a static library and check it in. I often go ahead and move the code elsewhere as well (with a README file with the .a that says where the code is and how it was built). This saves time on both build and checkout and is invaluable for large projects in my experience.
This might help: if the configuration of the project A is not found, Xcode will build Release config as a fallback (or maybe the first config of the list).
Then you can "force" the link using this tip: Xcode custom build configuration causes "library/file not found" for static libraries
Yes, this is not naturally supported by Xcode; when you build a target, it builds one configuration of itself and of all dependent targets.
The workaround, as Rob mentioned, is to have a dependent target that's an Aggregate Target type that comprises a single Run Script build phase, which simply invokes xcodebuild -configuration Release (or whatever).
You can specify the default 'fallback' configuration in the project info.
Change from:
Use 'Release' for command-line builds.
to:
Use 'Debug' for command-line builds.
And default will be 'Debug'.
