Installation Failed “Invalid argument” when trying

Question

I added a vanilla Today Application Extension and run with the new scheme created by XCode.
After it finishes building ("Build Succeeded" pops up), it failed straight away with this error:

Installation Failed
Invalid argument

I've been trying to find answers for 6 hours now, no luck so far. Please help!

Answer 1

Maybe you are bundling a conflicting "contents" referenced (blue) folder.

Hint: change the name of said "contents" folder :)

Answer 2

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

Answer 3

Try this:

1. Quit Xcode
2. Clean out ~/Library/Developer/Xcode/DerivedData manually
3. rm -rf "$(getconf DARWIN_USER_CACHE_DIR)/org.llvm.clang/ModuleCache"
4. iOS Simulator > Reset Content and Settings

Answer 4

I was getting the same error - although in different conditions - and it took me a while to realise that I had inadvertently messed with the Info.plist (thank you user2866588!) via a Search & Replace operation.

Once fixed that file, the error went away. It's a long shot, but you never know...

Answer 5

This issue occurred in my case when the phone's memory was too low to install the app. I've cleaned up the phone and voila!

Another hint might be this post.

Answer 6

I got this error when my test phone had low memory (around 288MB free). After restart and clearing some cached data, I was able to install my app.
