Code signing is required for product type 'Application' in SDK 'iOS5.1'

Question

I am using xCode 4.3.1. After i created a project, i build it and tried to Archive. Then i got an error saying; (This is my first project in xCode 4.3.1)

CodeSign error: code signing is required for product type 'Application' in SDK 'iOS5.1'

What does this mean ? and how to solve it ?

Answer 1

It means you haven't assigned a provisioning profile to the configuration.

Usually it's because "Any iOS SDK" must have a profile and cannot be set to "Don't sign".

All this and more is answered in the TN2250 Tech Note about Code Signing and Troubleshooting.

Answer 2

One possible solution which works for me:

1. Search "code sign" in Build settings
2. Change everything in code signing identity to "iOS developer", which are "Don't code sign" originally.

Bravo!

Answer 3

This error was caused, for me, by different circumstances. A downloaded project tutorial had a default setting of [Project]>Targets>Build Settings>Architectures>Build Active Architecture Only>Release = "Yes." I wasn't intending to build a release, so the solution was to set Release (which presumably requires not just a developer profile but distribution profile) to "No."

Answer 4

You can get around this by using the simulator if you don't actually need to be deploying to a device. That solved it for me.

Answer 5

I had this problem even though I had a valid provisioning profile for the device. It turned out that I had changed my developer account password and needed to update the password in xcode. This is done by going to preferences-Accounts-Apple ID and entering the new password.

Answer 6

Restarting Xcode did the trick for me. :)

Answer 7

The other issue here lies under Code Signing Identity under the Build Settings. Be sure that it contains the Code Signing Identity: "iOS Developer" as opposed to "Don't Code Sign." This will allow you to deploy it to your iOS device. Especially, if you have downloaded a GitHub example or something to this effect.

Answer 8

I had same problem with an Apple Sample Code. In project "PhotoPicker", in Architectures, the base SDK was:

This parametrization provokes the message:

CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 7.1'

It assumes you have a developer user, so... use it and change:

And the error disappears.

TN2250 Tech document was retired,To resolve this add IOs5.1 or 8.1 sdk field under Anyios SDK field

in code sign problem will solved

Answer 10

I have same problem because option In-App Purchase was ON in project's Capabilities. If your app is not need in-app purchases - turn it off, or you need to set a correct provision profile to Debug scheme.
