Invalid Signature error ! - ios

Question

I am trying to update my application , but after uploading the binary , Itunes connect sends me this email :
Dear Developer, Thank you for your
recent binary submission for "MY APP"
to the App Store. Unfortunately we
discovered an issue with your binary
that you will need to correct in order
for your application to proceed to the
review stage. The specific issue is
outlined below: Invalid Signature -
Make sure you have signed your
application with a distribution
certificate, not an ad hoc certificate
or a development certificate. Verify
that the code signing settings in
Xcode are correct at the target level
(which override any values at the
project level). Additionally, make
sure the bundle you are uploading was
built using a Release target in Xcode,
not a Simulator target. If you are
certain your code signing settings are
correct, choose "Clean All" in Xcode,
delete the "build" directory in the
Finder, and rebuild your release
target. Once you have corrected the
issue, please return to the
application's version details page in
the iTunes Connect Manage Your
Applications module and click on the
Ready to Submit Binary button. This
will take you through the binary
submission flow and return your
application version status to Waiting
for Upload. You can then use
Application Loader to upload your new
binary. If any other issues are found
with your submission you will be
contacted. Thanks, The iTunes
Connect Team
I am sure that my binary signed application with a distribution certificate NOT AD HOC !!!
what is your suggestion to solve this problem ! I NEVER HAD THIS PROBLEM !!!!!
I download the app distribution CER again but nothing change ! I have 6 apps on app store and never faced with this

Answer 1

Note that this QA is incredibly old. Apple have largely ameliorated this problem. Enjoy.
99 times out of 100, here is the problem:
Select "TARGETS", not "PROJECT"
Click on the name of your project at the Top Left of the main XCode6 window. (ie, just above where it probably says "Classes".)
Look at the large area which opens. Carefully look at the WHITE COLUMN ONTHE LEFT.
Choose "TARGETS" ... rather than "PROJECT"
Then, correctly set your certificate to the 3rd party Mac Developer cert.

Answer 2

I had the same message appear from Apple, and selecting "targets" not "projects" when setting code signing identity did NOT resolve my issue.
Turns out, as the last step of submitting the app to the store (via XCode4's Organizer panel - Archives tab), I was presented with a dialog sheet that showed the distribution certificate it was going to be submitted with, which was DEFAULTING TO A DIFFERENT DISTRIBUTION CERTIFICATE I had in my keychain - and NOT the valid certificate that I'd signed the app with!
Once I manually selected the correct distribution certificate in this last step of app submission, it went through fine. (I also opened up my Keychain Access app and deleted the offending distribution profile, that I didn't have any use for anymore).

Answer 3

A main point I'd like to offer is that Archive Validation (or submission thru App Loader) is supposed to identify the signature problem before sending the application to iTunes Connect. This is a first indication that the problem is related to a developer tools error.
Having witnessed this problem with multiple developers strengthens that hunch. In my experience the "Invalid Signature" diagnosis is not caught during client side validation as a result of a bug in older versions of Xcode. Devs simply update their OS X to 10.7.x, plus Xcode 4.2.1 and with no change to the project or code the app is ingested into iTunes Connect without issue.
Keep it in mind for others experiencing this problem...it's especially common on Snow Leopard with Xcode 4.0.2, 3.2.6 or less.
Apple's new publication touches on this point, see iTunes Connect Store - Binary Rejection emails - Invalid Signature.

Answer 4

I had exactly the same problem, checked everything but couldn't find any issues.
Problem ended up being because my project was stored on a FAT32 USB stick! Copied it to my Mac and everything worked perfectly after that.
Hope this helps!

Answer 5

I got the same problem and spent many evenings solving it!
For my app the problem was a question mark in the executable name. In the apple developer docs is noted you can't use special character in executable name but not which ones are allowed.
I changed the executable name in build settings and the upload works!

Answer 6

I have been battling this issue for almost a week! For me, it turned out that the Error email from Apple was completely wrong and misleading. (I knew that all of my certificates and code signing settings were in fact correct.) It turned out, that my app was getting rejected because there was an exclamation point (!) in the name. Apparently, only alphanumeric characters (A-Z, 0-9) and dashes are allowed for the product name. (Characters like ?#$% are not allowed.)
The Fix:
1.) Click on the blue project icon on the left panel in Xcode.
2.) Click on the build settings tab.
3.) Select the current target from the menu. (It's right next to the blue project icon.
4.) Scroll down until you see the "Packaging" Category.
5.) Find where it says "Product Name" and change it to a name that does not contain any special characters.
I hope this helps! Sorry I had to red-out my company info!
