There is no SDK with the name or path “iphoneos4.0”

Question

I download a sample of UICatalog and run it.When I compile it ,it shows the failed message:There is no SDK with the name or path \"iphoneos4.0\".I find the \"Base SDK\" of UICat

Answer 1

You have to make sure that you change to the "iPhone Simulator" under the project settings in the appropriate configuration (i.e. if you are building a debug build you have to change to the simulator under the debug configuration).

For some reason I was getting this error when I did change the simulator but realized that I was doing a debug build but changed to the simulator under the release configuration and not the debug configuration.

Answer 2

I just went Project -> Edit Project Settings -> Build -> then change the Base SDK to iPhone 4 simulator or I'm assuming whichever SDK you want to use. I never had to specify the build for a given target, although my program was created on a mac that was already configured to use the iPhone 4.0 simulator.. so perhaps the targets were set for the simulator SDK and the project itself wasn't? Either way... just glad it works.

Answer 3

My problem was that in the sample code another xcodeproj was embedded. So I looked after that file with Finder, opened it with Xcode and than the same as Dan said: Project -> Edit Project Settings -> Under "Architectures" set Base SDK to "iPhone Simulator x.x" (the latest one you have installed)

Answer 4

Select the root level of the project, in "Groups & Files". It's blue. Then hit command-I to get its Info.

Pick "Build" from the segmented controller at the top of the info window. In the first section of that panel you'll see Base SDK as one of the first few lines of options. Select the latest version of the SDK you find in there, and close the window to save your options.

Build-and-run the project, and you should be good to go.

EDIT, because I see from the comments that people are finding this answer who have a slightly different question than the OP's, so here's one other thing to try. It could also be you have "iOS Device" selected as your build target. If so, and if what you really want is for it to launch into the simulator, select "Simulator" instead.

^{Many answers here, none seem to be complete enough about this, and it's all a mess. But they are all helpful. Here, I just want to compile all helpful pieces in one answer. Thanks to Larry (who have almost everything compiled into steps already), Steve, Dan Ray, dkk, geowar and lqf.}

This picture from apple is a little decieving and outdated (talking about iOS SDK 4.0 and we're currently at 4.1) but it does show where you should change the project settings. Just select iPhone Simulator 4.0 if it was previously on iPhone Device 4.0.

Other than that, they say "Targets can override build settings defined at the Project level". So, yeah, also go ahead, open Targets and set all of their Base SDK back to default by pressing delete on it. If they were bolded, they'll become regular indicating a default value, which should be iPhone Simulator 4.0 if you did the first step right.

Just realize there are many places where Base SDK can be wrong:

• Under Project Info
• Under Target Info
• Under different configurations for both Project and Target

And that under Target it should be set to default, which is value from Project.

There's still something about the overview combo sometimes having and sometimes not having more than 1 option such as "Device" and "Simulator" that I just couldn't understand yet, but this is another potential configuration place for Base SDK being wrong.

Answer 6

I had the same issue with another Apple sample app. The only way I could resolve it (in fact, the only way I could get the option of running in the simulator at all) was to change from debug to release and back. The dropdown still shows Base SDK Missing but if you click it, the simulator options are there and it builds.

I think that's a bug.
