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

Question

Whenever I try to run my app in Xcode 6 Beta 4 I am getting the error   The file  MyApp app  couldn t be opened because you don t have permission to view it    This error appears no matter what simulator or device I target   I have tried    Deleting all Derived Data from Organizer in Xcode Repairing permissions on my drive Manually elevating the permissions of the built MyApp app Restarting my computer   Has anyone else run into this problem and found a solution

None of the provided answers worked for me. In my case, I finally fixed the error by updating the target architectures in Build Settings/Architectures/Valid Architectures to $(ARCHS_STANDARD), as arm64 was missing. This was not prohibiting the project to build, although a warning was issued recommending updating the valid architectures, but the "app could not be opened" error was shown at run time.

I surmise this error is rather generic and not always linked with a permission issue, but may be displayed when the generated app package is invalid.

For me the error was in the  plist file at the key CFBundleExecutable  I had renamed the executable removing a space that was between two words   Eg  from  Wild Racer  to  WildRacer    Took 1 day to spot it     Xcode is soooo unhelpful in the debugging

Well in my case  I just rename the Bundle Name and Executable file values in info plist same as project name  It worked for me

Don t know if the problem is related but maybe it can be a solution for anyone pulling the hairs like me    In my case  I have a project with a lot of targets  Each target is a customisation of that base project which is a Cocoa Touch Static Library and the targets  Applications  Even if the main file is added into the library compilation  but not in each target  that error message appears  So what I did  Manually added the main file to each target in the Compile Sources section and bingo  all fine

I tried all of the listed answers and none of them was useful  The problem was due to existence of an another plist file linked from a submodule via cocoapods  Luckily this was my own module  so I just deleted this plist from the submodule project and reinstalled pods   solution  Later on I understood that the key of the problem was in the name of that second plist  simply info plist  You may rename the file and relink it via a sources section of a submodule  That second plist file had a unique name  so Xcode was not supposed to become frustrated  Even my target settings pointed on a main plist  not on a info plist  Looks like Xcode takes special consideraions about that name  The bug reproduced in Xcode 6 4 and Xcode 7 0

What we didn t do right was to not apply with the accurate code when signing in the Build Settings  We fixed the issue up this way  Enter into Build Settings    Code Signing    Code Sign Identity  Then  apply with your iOS Developer ID for  Debug   but be sure to apply with your iOS Distribution Profile for  Release  We didn t apply correctly  so we couldn t have permission to ask for the App from the server  actually  Anyway this post forced us to revise all the parameters and requirements  so we pretty appreciate all your answers  Regards  T

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
