Error While Build Project Xcode Says:"You Don't Have Permission"

Error while build project Xcode says : you don't have permission

Go up to the folder containing the project in your Finder.

Right Click > Get Info

Go to the bottom of the Info pane, and click the little lock, type in your password when prompted.

Then, change permissions for yourself to read+write.

Click the little gear below, and apply to all enclosed items.

Close the lock once you are finished!

If this doesn't work, Change the value of "Compiler for C/C++/Objective-C" to "Default Compiler (Apple Clang)" under the Build Settings of your target.

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

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.

Xcode: Do not have permission to view app

Solved.

Some of my project files (my font files) were automatically uploaded to my iCloud - this was causing the permission issues, as I think I wasn't allowed to save an app to my phone that has access to my iCloud. After downloading the files and saving them locally, the app ran on my iPhone.

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

error: 'Flutter/Flutter.h' file not found when flutter run on iOS

I found a solution!

Backup ios/Runner folder.
Delete the ios folder.
Run flutter create (your project name). in the previous folder where you have your project(cd users/user/"projects_folder")
(this will recreate your ios folder).
Paste your Runner backup in the ios folder (into the project).
Open Runner.xcworkspace (into ios folder) and there, check the Version, the Bundle ID, all the info.
(If do you Have Firebase, you have to copy and paste again the Google Service-Info.Plist into the Runner folder (Always through Xcode) (If do you do this manually, it doesn't work).

Finally, flutter run and should work!

If flutter run fails:

cd ios
pod install
cd ..
flutter run
