问题

Hi guys,

I am about to build watch app target from existing project. I encountered a strange error upon finishing build that unables me to run the watch app properly. Here is the attached screenshot.

Environment

OSX 10.10
XCode 6.2 Beta
Simulator iPhone 6 iOS 8.2

When I try creating new watch app project and try the Lister demo app they work just fine. So I am suspecting there is something wrong with my existing project but not sure what since the error message is not really explanatory. I appreciate any leads or helps given, thank you for your time.

EDIT: After few investigation turns out extensions do not work as well.

I had the same issue. This sequence helped for me:

Xcode doesn't like it when you have a referenced directory called 'Resources' within your resource bundle (see timrex)

1) Remove 'Resources' directory from your project's tree;

2) Reset content and settings in iPhone simulator;

3) Press Shift+Cmd+Alt+K and click 'Clean' or Shift+Cmd+K in xCode window;

Check if the Bundle Identifier isn't empty in the Info.plist

After 2 days of research I have found the answer which I believe is an xcode bug.

Basically this is caused by having different build name on your XCode build settings. Making them uniform should solve the problem. As shown here https://devforums.apple.com/message/1047770#1047770

I hope this helps anyone stumbled upon this question.

I got my error fixed by setting the project's "Product Bundle Identifier". It was empty since my project was being generated by Gyp and I hadn't set that particular setting on the project.

回答5:

I ran into the same issue and got it resolved by cleaning the phone's memory since it was too low to install the app.

回答6:

This issue can be resolved simply by emptying the trash.

回答7:

I fixed this by first building for an actual device - once I'd done that at least once, the simulator ran fine.

回答8:

I got it working after I tried everything mentioned here, then deleting the app from the device and restarting XCode. Those two steps were mentioned here: https://stackoverflow.com/a/28232381/1586277

I have no idea what combination of steps fixed it though.

回答9:

I got this issue while running on simulator. I rebooted the system and the issue gone.

I just had the same issue. My fix was to delete the temporary project files in the derived data folder:

rm -R /Users/username/Library/Developer/Xcode/DerivedData/projectname

Check your connected device has enough storage space. I had this issue when I tried to run in my iPhone. I cleared the storage by deleting couple of apps and tried to install again and then it works.
