"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

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

---

I've fixed it by cleaning a build folder. Just went to 'Product' menu and Option+Click 'Clean'. After that a problem was resolved.

---

There was a problem with the Info.plist of the project. I created a new project with the same name in Xcode 6 beta 4 and then replaced the real project's Info.plist with the new one. The project then built and ran fine.

Look at the diff, it appears like the plist might have somehow gotten mixed up with a playground's plist. The bundle identifier was "com.apple.dt.playground.iOS-18300-13" and the executable and bundle names were "iOS" along with some other oddities.

I've had same this error in Xcode 8.2. The reason I found out for me, another Info.plist is added in my project while adding library (manually copy).

So that Xcode is getting confused for selecting correct Info.plist.

I just removed that Info.plist from the added library.

Then it is working fine without any permission alert.

---

Please check if you have changed Executable file => $(EXECUTABLE_NAME) to any other name. If you have changed this name then it shows this error. Please replace it with $(EXECUTABLE_NAME).

---

Product -> Clean (command shift K) fixed it for me

---

My goodness!! I spent hours to resolve this issue.

On XCode 7.3 I was having project with no issues.

Mistake I did

I just Added physical folders and moved my files into them, problem started.

I tried everything

Default compiler

Clean and build

Reset simulator and reboot simulator, Xcode, iPhone even mac

Updated Info.plist

Deleting Derived Data

Editing the permission on the folder of the project

Checking my architectures

nothing worked :(

How I resolved

I was about create new project and then I just deleted those physical folders I added, clean build and YESS!!

It works!!

Try "cmd+shift+k" to clean the project and rebuild. At least it worked for me

---

Sometimes opening old project in new version Xcode will get this message.

Go to Issue navigator and follow the warning hint 'Upate to reconmmented settings'.

Boom, magic!

---

I had similar issue (xCode 6.2) for sample code downloaded. I tried to set Executable Name to Default in Info.plist but this didn't worked.

Instead change Compiler for C/C++/Objective-C to Default compiler (Apple LLVM 6.0) instead of Unsupported Compiler(com.apple.compilers.llvmgcc42) for project.

My Application was working fine on XCode 9.4, but when I opened my project in XCode 10 I was experiencing this issue. For me the issue was the build setting. I found the answer in this page https://forums.developer.apple.com/thread/112141.

In short go to File > Workspace Settings… > Build System and change it to "Legacy Build System"

---

1) Go Firstly Build Options.

2) Then changed the value of the "Compiler for C/C++/Objective-C" to Default Compiler.

clean and working :-)

---

I found that changing my compiler to LLVM 6.0 in the Build Options was enough for me (xcode 6.1)

I got same error on my Xcode 6.1.1 for a project downloaded from gitHub which was committed 4 years ago. For me, setting Architectures to the default value Standard architectures(armv7,arm64) and Compiler for C/C++/Objective-C to Default Compiler in Building Settings worked.

---

I had the same issue in my project. Later on found that third-party (fmdb for SQLite) file used in project contained Info.plist.

Simply deleting the Info.plist file worked for me!

I recently meet the same problem for running an old project (initially created in Xcode 4.x) in Xcode 6.0.1.

I fixed the problem by changing the Architectures in Building Settings to the default value, which is "Standard architectures(armv7,arm64)".

Hope this could help anyone who got similar problems :)

---

I've had this error with a number of my older projects that I am getting out of the cupboard to update. It seems that using Xcode 6 with older code seems to bring this about for some reason.

I have fixed this in all projects that I have done this with by:

Delete Derived Data in Product: do a clean go to Build Settings in the project Target and go to Build Options and change the value of the "Compiler for C/C++/Objective-C" to 'Default Compiler'.

---

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.

---

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 I did is here:

I deleted VALIDARCHS from Project

I deleted VALIDARCHS from Target

Build Active Architecture Only = YES (for Debug) Architectures

Standard Architectures $(ARCHS_STANDARD)

Also, File -> Project/Workspace Settings == New Build System

Xcode Version 12.0 (12A7209)

---

I had this similar problem. Somehow my value for the key Executable File got mixed up. Just change it back to ${EXECUTABLE_NAME} (Under your project > Info). Worked for me!

If you google the text of this error message you will find maybe 20 threads across StackOverflow, Apple dev forums, Reddit, etc. about Xcode failing to be able to run a compiled executable with this error message.

In these threads you will find many people offering various suggestions about how to fix the problem: changing product name to match project name, changing build phase options, something with info.plist, changing compilers to or from Clang, etc. Presumably the suggestions are offered in good faith because they solved the problem for someone, but the answers are so varied that it is clear that the error message is generic and this is an important point if you are receiving it: this error seems to mean that something is wrong with the binary. Ignore its actual text: it may have nothing to do with permissions.

There is no general solution to this error. The error message is totally generic; assume it means "bad binary file". The solution if you are receiving it depends on what you are trying to do, what has changed, why you are seeing this error all of a sudden. Google the specifics of your situation rather than this error message.

In my case, and I have a feeling this is a common case, what I was trying to do was build an old iOS project, nine years old I think, on modern Xcode. The solution was to switch to the legacy build system which led to a compilation error because in the old project there were not modern architecture targets, which could be fixed by manually adding them.

---

In my case main.m containing the main(...) function was not contained in the list of "Compile Sources" in "Build Phases". To check if this is the case, enter into Build Phases and look, if your main.m appears in the "Compile Sources" list.

---

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.

---

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!

---

What solved it for me was setting Build Active Architecture Only from No to Yes.

---

with X-code 6.3.2

[Build Settings] Options. [All]-[Build Options]-[Compiler for C/C++/Objective-C]-[Default compiler (Apple LLVM 6.1)]

Then rebuild the project, and it runs ok.
