Ad Hoc deployment fails when shipping Default.png images

Question

I'm an experiencing an issue where I can't install an Ad Hoc version of my application via TestFlight. The application downloads, but at the installation step it shows something like "YourApp can't be installed", with the following messages appearing on the console:

Sep 17 16:08:24 unknown installd[4767] <Error>: 00381000 verify_signer_identity: Could not copy validate signature: -402620393

Sep 17 16:08:24 unknown installd[4767] <Error>: 00381000 send_error: Could not send error response to client

codesign --verify doesn't return any errors, and I have double-checked that I'm using the correct Ad Hoc provisioning profile (codesign --display -vvvv confirms this).

However, as soon as I remove all the Default.png images from the application, the install works and the application can be run afterwards. The IPA has a size of about 10 MB without and 15 MB with all Default.png images.

Any ideas?

Answer 1

Have you tried installing the IPA direct to your device via Xcode?

Connect device.

Open Xcode Organizer / Devices Tab / Select your device / Applications.

Click the + (add) button at the bottom left, select your app.

If this install fails as well, I suspect there's something up with your Default.png image. If you are scripting image conversion, it's worth mentioning that I've had lots of issues in the past using the sips command-line utility creating png images that Apple doesn't like, so I've stopped using that. I now use ImageMagick instead and have not had any trouble since.
