In Xcode 6.0.1,I have to delete all my data in DerivedData,then I run my app,it builds successfully but I can't run it on the iOS Simulator iPhone 5. Xcode warning :
Invalid or missing Program/ProgramArguments
Can anyone help me ?
Launching the Simulator, though, always requires opening Xcode and going to Developer Tools. Because the Simulator. app is embedded within the Xcode app bundle, apps like LaunchBar won't find it to index it. LaunchBar, which is my launcher of choice, also ignores aliases, so dragging Simulator.
If there is any issue in the project build, then first step is to clean the build, which will clean the build and make a new build from scratch next time when you run the code. To clean the build you can use the shortcut Command+Shift+K or Menu Bar → Product → Clean .
Open Xcode and click Menu > Xcode > Preferences > Select Components, and then choose the simulator version you want to download.
I was facing this issue when i migrated my project from xcode 6.4 to xcode 7 beta 6. To solve this issue, you have to : From top menu options GOTO, xcode -> Preferences (cmd + ,) -> Locations select the command line tool to your current version.
Now run your app, it should work fine.
