Introduction

Even though iOS 7.0 is a legacy target, the error "No code signing identities found" still means the same basic thing today: Xcode cannot find a valid signing certificate and provisioning setup that matches the app you are trying to build. The problem is usually not the source code. It is the signing chain.

What Xcode Is Looking For

To sign an iOS app successfully, Xcode needs a matching set of information:

• a valid signing certificate in the keychain
• a provisioning profile that matches the app ID
• the correct team selected in the project settings
• a bundle identifier that matches the provisioning profile

If any one of those pieces is missing or mismatched, Xcode can report that no usable code signing identity is available.

Start with the Apple Developer Account in Xcode

In Xcode, the first thing to check is the account and team configuration.

Typical path:

• Xcode preferences or settings
• Accounts
• Apple ID and team membership

If Xcode is not signed in properly, or the expected team is not available, the project may not be able to download or use the right signing assets.

For old projects, this is especially common after moving to a new Mac, a new Xcode install, or a restored keychain.

Verify the Certificate Exists in Keychain

A valid signing certificate must exist in Keychain Access with its private key.

From the command line, you can inspect available signing identities:

security find-identity -v -p codesigning

If that command shows no valid identities, Xcode has nothing to sign with.

If it shows identities you do not expect, or expired ones only, the next step is usually to refresh or recreate the development certificate in the Apple Developer portal and re-download the profile.

Check the Provisioning Profile Match

The provisioning profile must agree with:

• the bundle identifier
• the certificate
• the build type, such as development versus distribution
• the device list for older manual development workflows

If the app's bundle ID is com.example.app, but the profile targets a different identifier, signing will fail even if the certificate exists.

That is why code-signing errors often look mysterious: several parts are individually present, but they do not form one valid combination.

Automatic Versus Manual Signing

Modern Xcode often works best with automatic signing for straightforward apps. If the project is old and still configured for manual profiles, the signing settings may have drifted badly over time.

For example, a legacy project may still reference:

• an old team ID
• an expired profile name
• a removed code-sign identity string

If possible, switching the target to automatic signing and selecting the correct team can simplify recovery.

If you must stay on manual signing, verify the profile name, certificate, and bundle identifier very carefully.

Build Settings Still Matter

Open the target build settings and inspect:

• Code Signing Identity
• Provisioning Profile or profile specifier
• Development Team
• Product Bundle Identifier

The old project may have one set of values for Debug and another for Release. It is easy to fix one configuration and still fail on the other.

That means you should check both the target settings and the project-level settings, because inherited values can hide the real source of the mismatch.

A Practical Recovery Sequence

A reliable repair workflow is often:

1. sign into the correct Apple account in Xcode
2. verify the team is visible
3. check Keychain for a valid signing identity
4. confirm the bundle identifier
5. refresh or recreate the provisioning profile
6. clean the build folder and rebuild

If the project is very old, a full cleanup of stale profiles and derived data can also help because outdated signing artifacts may still be referenced.

Why iOS 7.0 Makes This Feel Worse

Older iOS projects often come from older Xcode versions, older certificate setups, and manual signing conventions that were common at the time. So even if the app still compiles, the signing configuration may have decayed across:

• expired certificates
• replaced Macs
• renamed teams
• old provisioning-profile references

That makes the issue feel iOS-7-specific when it is really a signing-asset consistency problem.

Common Pitfalls

One common mistake is checking only the certificate and forgetting that the provisioning profile must match the same app ID and team.

Another pitfall is having a certificate in the keychain without the private key, which still leaves Xcode unable to sign.

A third issue is fixing Debug signing while Release still points to an old identity or profile.

Finally, older projects often carry stale manual settings that conflict with modern automatic-signing expectations. In those cases, simplifying the project signing setup is often the fastest fix.

Summary

• "No code signing identities found" means Xcode cannot assemble a valid signing chain for the build.
• Check the Apple account, team, certificate, private key, provisioning profile, and bundle identifier together.
• Use security find-identity -v -p codesigning to confirm valid signing identities exist on the machine.
• Verify both Debug and Release configurations, especially in older projects.
• For legacy iOS projects, stale manual signing settings are often the real cause.
