Installation Failed “Invalid argument” when trying to run Today application extension

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

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

Answer 2

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 3

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

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

Answer 4

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 5

This can also happen in Xcode 7 because "Upgrade to recommended settings" will change CFBundleIdentifier to point to $(PRODUCT_BUNDLE_IDENTIFIER) instead of the old $(BUNDLE_IDENTIFIER).

Apple says in the Xcode 7 release notes that PRODUCT_BUNDLE_IDENTIFIER is now "the recommended place to set the Bundle Identifier for a target." So if you're using BUNDLE_IDENTIFIER anyplace else in your project, be sure to change it to PRODUCT_BUNDLE_IDENTIFIER to keep things in sync.

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 7

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.

Answer 8

Image description here.!! I got this Error Just Enter Bundle Identifier. (You can get bundle identifier by right click on info.plist and go to Open as than Source Code here just find this CFBundleURLSchemes below this name a string tag contains your bundle identifier) Copy Bundle identifier and past it on TARGET select General now on Identity you will see Bundle Identifier paste there and enter. then just run the code. Happy Coding!!!

Answer 9

What I found is that info.plist file should never been localized! I tried to localize my project and tried to tap Localization on all plist and string files. As a result, I could not install my app to Simulator, invalid argument error.

I spent 1.5 days trying to find out reason. I tried all the solutions as listed above, but with no luck. Finally, discard all my localization changes and redo it again. This time, I tried to localize one file first, and then compiled codes and trie to run my app on Simulator.

The issue is info.plist file. You could localize it. The result is that en version is moved en.lproj folder. That is to say, no more info.plist file in the project folder. As a result, Xcode could not find it and exception raised.

Another way to verify it is to check your project settings. Select your target and general tab. The Identity should be like:

If your project settings are something like this, you have to locate info.plist, that means info.plist is missing.

You just cannot locate localized info.plist in en.lproj folder from project settings.

Don't localize info.plist file directly. You can localize it by localizing infoplist.strings file.

This may be one of reasons to get invalid argument exception, as in my case.

I also wrote a blog on this.

Answer 10

I got the same issue and it was because of low memory on phone. I deleted some apps and restarted the phone which brought by available storage.

Answer 11

I got this error after installing new pods (AWS) to my project. Somehow the entry in the Build Settings for Info.plist file was cleared. Entering the correct filepath (find in finder) my project finally compiled again.
