Launching Application from Xcode 6: "The file cannot be opened because you do not have permission"

I have a Swift project in Xcode 6.3.2 that consists of an application project using a framework subproject. Everything builds and connects perfectly. Only when Xcode tries to run the application file does this error appear: "File 'AppName". Could not be opened because you do not have permission to view " The project was built and worked successfully before.

I understand there are more questions like this one. I have read and tried all the solutions given in this question and several others.

I tried:

• Clean
• Clear build folder
• Delete derived data
• Checking the rights to directories and the application file itself
• Setting Build Options> Compiler for C / C ++ / Objective-C for the default compiler
• Configuring Build Options> Architectures for Standard Architectures
• Editing info.plist, installing Executable $ {EXECUTABLE_NAME} and package name in $ {PRODUCT_NAME}
• Replacing info.plist with a new one

Are there any other possible causes and solutions for this error that anyone has encountered?
