How to Fix the "MyApp.app couldn't be opened because you don't have permission to view it" Error in Xcode 6 Beta 4 🚫📂

So, you're trying to run your app in Xcode 6 Beta 4, but you keep getting hit with the pesky error message:

The file "MyApp.app" couldn't be opened because you don't have permission to view it.

Don't fret! You've come to the right place. In this blog post, we'll explore common issues and provide you with easy solutions to resolve this problem. Let's dive in! 💻➡️🔧

The Problem

This error message can be frustrating, especially when it appears regardless of the simulator or device you're targeting. You've already tried a few things, such as deleting the Derived Data, repairing permissions on your drive, manually elevating the permissions of the built MyApp.app, and even restarting your computer. Yet, none of these solutions seem to work. 😓💢

The Solution

One potential cause of this issue is the introduction of App Sandbox in Xcode 6 Beta 4. The App Sandbox restricts certain operations that an app can perform and limits access to certain files and directories. If you're experiencing the "permission denied" error, it's likely that Xcode is blocking your app from accessing the necessary resources. Here's what you can do to fix it: 💡🛠

Solution 1: Grant Full Disk Access

To resolve this issue, you need to grant Xcode full disk access. Here's how:

1. Go to System Preferences on your Mac.

2. Select Security & Privacy.

3. In the Privacy tab, click on Full Disk Access in the left sidebar.

4. Click on the lock icon in the bottom left corner to make changes.

5. Enter your password to unlock the settings.

6. Click on the + button and navigate to the Applications folder.

7. Select Xcode and click Open.

8. Ensure that Xcode is now listed in the Full Disk Access section.

Once you've granted Xcode full disk access, try running your app again. 📂🔓

Solution 2: Change App Sandbox settings

If Solution 1 didn't work for you, you can try changing the App Sandbox settings for your app. Here's how:

1. Open your project in Xcode.

2. Select the target for your app.

3. Go to the Capabilities tab.

4. Scroll down to the App Sandbox section.

5. Disable the App Sandbox option.

6. Clean and build your project again.

By disabling App Sandbox, you're essentially telling Xcode to remove the restrictions that might be causing the "permission denied" error. Give it another go and see if this fixes the issue. 🔄✅
