“ARC is available in Xcode 4.2, currently in beta, and only when compiling with Clang (a.k.a. “Apple LLVM compiler”). The setting is called, obviously enough, “Objective-C Automatic Reference Counting”. Turn it on, and off you go. If you’re working on existing code, changing this setting will produce an enormous quantity of errors. ARC not only … Read more
Try this: Open Organizer then Project Tab. Clear the “Derived Data”. Xcode should re-index your project then and code sense should work. At least worked for me.
These solutions are way too difficult. The problem is that you have removed the project from filesystem but SVN still thinks they are there. Detaching project from SVN will work, the same for removing .svn folders BUT that is going to destroy your repository! It is much easier to open console, browse to your folder … Read more
Select the project file in the document explorer. On the Right margin of the Xcode window make sure to display the right drawer view if it isn’t already there (it usually has Object library and Quick Help). In the top margin, click on the icon that looks like a document (rather than the one with … Read more
As per Apple’s documentation: In the project navigator, select your project. Select your target. Select the “Build Phases” tab. Open “Link Binaries With Libraries” expander. Click the + button. Select your framework. (optional) Drag and drop the added framework to the “Frameworks” group.
The accepted answer is wrong. Creating a new target is how you create a separate iPad app from an iPhone app (i.e. a project that can be compiled into either an iPad or iPhone app), it is not how you convert an iPhone app to a single universal app that will run on iPhone or … Read more
Interface Builder filters colors through your monitor’s current color space by default. You can change this in Xcode4 IB by bringing up a Colors dialog, clicking the Sliders tab, then clicking the little dropdown button under the magnifying glass that looks like a color spectrum. This will bring up a list of available color spaces … Read more
Check the product name in build settings and make sure everywhere it is Myapp. If that is done, Close your project -> go to finder. Right click on your .xcodeproject file and click on show package contents. Then right click on your project.pbxproj and open it in some text editor. Then search for Myapp-temp-caseinsensitive-rename and … Read more
Editing the scheme (swapping around build targets, un-/check “Parallelize Build” and/or “Find Implicit Dependencies”) didn’t work for me. I still had to clean build the project, after any code change in the static lib. Searching the dev forums, I finally found this answer, which worked wonders. Make sure the Identity and Type inspector is showing … Read more
Make sure you have selected a device from the drop down menu and not the simulator. Then in XCode 4 go to product -> archive. After the build is complete open the organizer and selected Archives. Here you will find your build, from here you can then select share, next XCode will ask with which … Read more
