问题
I upgraded to xcode 5.0 today. I then pressed play to run my project in the iOS simulator. This initially worked. Then I decided that I wanted to run the profiler. When I did that, I got the message:
Xcode cannot run using the selected device.
Choose a destination with a supported architecture in order to run on this device.
I looked at a couple past posts on this problem and decided to do a Clean and Build. Now I can no longer run in the profiler or the simulator. I consistently get the message:
Xcode cannot run using the selected device.
Choose a destination with a supported architecture in order to run on this device.
How can I resolve this?
Here are various settings:
My Deployment Target is 6.1
I have also tried changing the deployment target to 7.0, but that did not work either
回答1:
It appears that the problem is not related to the architecture in the build settings as the error might suggest. Rather, I found that the problem seems to be related to the Build Options Compiler for C/C++/Objective C. I was using a gcc compiler (com.apple.compilers.llvmgcc42) and Xcode 5 has marked this as unsupported.
If I change the compiler to apple's default Apple LLVM 5.0, the project builds and it can now run in the simulator. The downside is that I have a lot of compiler warnings from code related to cocos2D v1.0 source code. But, at least I have a way forward.

Please follow below step
1>Go to Project Build setting
2>Change compiler for c/c++/objective c as Default compiler(Apple LLVM 5.0) (see in below image)
回答3:
I had to change compiler for Default compiler (Apple LLVM 5.0) at two places:
- Build Settings > Build Options > Compiler for C/C++/Objective-C (change to LLVM)
- Build Rules > Files *.mc using GCC (change to LLVM)
Hard to find because code compiles even if Build Rules point to an undefined compiler.

After inspecting all the build settings for 15 minutes, this worked for me (Xcode 5.0.2):
Quit and restart Xcode
回答5:
Check that the Executable File (also known as CFBundleExecutable) in the Info.plist file is set to ${EXECUTABLE_NAME} as opposed to any hardcoded value. This will ensure that even if you change your project name or target name or scheme name, that it still works.
回答6:
This issue often occurs after duplicating targets on older projects.
Set the following in your Info.plist for the target:
Bundle Name = ${PRODUCT_NAME}
Bundle Display Name = ${PRODUCT_NAME}
Executable file = ${EXECUTABLE_NAME}
Build and run with these settings, after a successful build they can be changed to anything you want.
回答7:
This works for me: "Quit and restart Xcode". I recently updated something and the testing device on Xcode said: 'iDevice' not iPhone or iPod. So I restarted then my iPhone came back to the target list.
回答8:
I had this error when I changed the value of the "Bundle name"-key in the Target Properties. Changing it back to "%{PRODUCT_NAME}" solved the problem for me.
