"The file "MyApp.app" couldn't be opened because you don't have permission to view it" when running app in Xcode 6 Beta 4

Could not add write permission to the file Xcode?

Go to the Folder in Finder where the xcode project is and right click -> Get info. The permissions and the bottom should be set to read/write and in my case they were. The trick is to click the settings icon at the bottom and select "Apply to enclosed items".

I use Xcode6 GM. I encountered the same problem. What I did was to go to Build Settings -> Build Options. Then I changed the value of the "Compiler for C/C++/Objective-C" to Default Compiler.enter image description here


Having the problem on DEVICE too (not just simulator)?

The other solutions only fixed it for me on simulator, not device.

For me this problem occurred (in Xcode 6) when I would try to change the main info.plist properties whilst trying to change my app name.

In info.plist I had changed Executable File name to something other than the default ${EXECUTABLE_NAME}...

I had mistaken this field for the field that changes the name of the app under the icon on the springboard.


In Xcode do the following

Window --> Organiser --> Projects --> The app with the issue --> delete button in Derived Data.

I then cleaned the project and voila

works


For me, a simple Product -> Clean worked great
