Xcode cannot run using the selected device after upgrade to Xcode 5.0

Question

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 th

Answer 1

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.

Answer 2

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.

Answer 3

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)

Answer 4

After inspecting all the build settings for 15 minutes, this worked for me (Xcode 5.0.2):

Quit and restart Xcode

Answer 5

I had to change compiler for Default compiler (Apple LLVM 5.0) at two places:

1. Build Settings > Build Options > Compiler for C/C++/Objective-C (change to LLVM)
2. Build Rules > Files *.mc using GCC (change to LLVM)

Hard to find because code compiles even if Build Rules point to an undefined compiler.

Answer 6

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.
