Error installing iPhone application on device

Question

I installed all my certificates and keys today and am trying to run my project on my iPhone. I meet this strange error:

During the installation phase, your mobile device detected an unexpected error (0xE800003A): Application Check

Competing with the Apple Developer Forums, I tried to install new certificates and training profiles, as well as edit Info.plist , but no matter what I do, I can not run the application on my device.

The only thing I can think of is that the name of my project in Xcode is slightly different from my development profile (it uses a question mark), but I named it according to Apple conventions: com.mycompany.myapp , so I don’t sure this problem.

Any ideas?

Edit: I rebooted the phone, rebooted Xcode, cleared my goals, set a new application ID and the corresponding provisioning profile, and still nothing. Any other ideas?

Answer 1

It turned out that I had 2 certificates in trinkets, which simultaneously copied each other! Hope this helps people in the future.

Answer 2

You must create a wildcard application identifier; com.mycompany. *. This can help.

Answer 3

I have met this many times. What I am doing is to clear all targets, disable xcode and hard reset my phone.

Answer 4

This is a different error than the more common problem of obtaining a certificate incorrectly ...

Restore your phone (using Xcode Organizer to restart the latest OS) to be safe, do not restore the backup when synchronizing with iTunes for the first time (it will still keep your number when synchronizing, even if you press "t use backup). I had to do this several times, the last was when he was in the middle of deployment, when I unhooked the phone from the cable (I had to answer the call).

First, try rebooting (from the phone) by disabling Xcode. But if that does not solve, recovery is a way.

Answer 5

The console tab in Xcode Organizer sometimes provides useful hints as to what happens during the installation phase. In one case, my problem was my application that already existed over the phone. I uninstalled the application and installed it.

Despite this, it seems that many error messages have been added to this one cryptic message, and to really diagnose what is happening, I found the Console tab very useful ...

Answer 6

Another thing to try is reinstalling the iPhone SDK. I encountered this error when I first received my developer key, and that was the only way.

Answer 7

I just want to tell everyone when you go to editing Targets-> be sure to set the “configuration” in the upper left corner of “All configurations” or the correct configuration for which you are building (Debug or Release). You might think that you have everything right, but it will be the wrong configuration.

Answer 8

I saw this error on a properly prepared device that had successfully installed applications from Xcode before, and I was lucky to restart the device and try again. Maybe this will help.

Answer 9

Try launching Release mode instead of Debug. I have a working draft with this problem. I don’t know what the problem is, but it works in Release mode, but Debug mode gives an error code.

Answer 10

I have a support ticket open with Apple dev support for the same problem, and (FWIW). I will post their recommendations if and when they can make my toolchain work.

Answer 11

Try the following: (source: http://ephemera.lifewithalacrity.com/iphone_development/ )

Although this is supposedly only for Distribution builds, it helped me install my version of Debug on my iPhone again after it mysteriously broke yesterday.

"just check three times that all code signatures in your project properties are clear or the default"

Note that these are PROJECT properties, unlike the TARGET properties. I set my default code signing provisioning profile and deleted the code signing identifier string.
