Installation Failed: Invalid Argument -iOS Extension

Question

https://i.stack.imgur.com/nm3Jg.jpg

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;

This fixed my issue. I added a complete folder called Resources to the project and that was the issue. I then created a folder manually and added the files to it, also named Resources, and that worked. – Martin Schultz Oct 14 '15 at 12:15

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.

What do you mean by "build name"? Are you talking about the "product name"? – petehare Jan 20 '15 at 20:19
This worked for me! I renamed my Project Name to match the Product Name (actual App name). – Gabe Karkanis Mar 19 '15 at 03:45

Great! And so odd. What I had to do is change the entry of "Bundle Name" in Info.plist from `$(PRODUCT_NAME)` to `$(TARGET_NAME)` to ensure the names are identical, even though "Product Name" in Build Settings was already set to `$(TARGET_NAME)`. Perhaps it didn't properly expand the variables. – CodeSmile Jul 14 '15 at 13:47

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.

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.

This issue can be resolved simply by emptying the trash.

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

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.

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

I have tried this by deleting content of this folder, but it has not helped. After I have deleted whole folder, restarted Mac and emptied trash (as advised by Abdul Shamim), problem is gone. I have not used any extension, so using extensions might not be only source of this problem. – Reconquistador Jun 05 '15 at 05:41

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.

Check your device's storage.

I had this issue and deleting some apps was the only solution for me...

I could fix this problem by switching to a different simulator (iPhone6 instead of iPhone6s) in my case).
