Error: No code signature found

Xcode: 12.5.1
macOS: 11.5.2

I have an app I'm building in Xcode that has several dependencies (Cocoapods). After adding one framework in particular (Wikitude AR framework), my build succeeds but I can no longer install the app on my device (iPhone 11, 14.7.1). The install fails with the following error:

System Information

macOS Version 11.5.2 (Build 20G95)

I assume that this means the framework needs to be signed somehow. However, if I add the framework to "Frameworks, Libraries, and Embedded Content", the build immediately fails with the following error:

Multiple commands produce 'my-cool-app/ios/Build/Products/Debug-iphoneos/my-cool-app.app/Frameworks/WikitudeSDK.framework':
1) Target 'my-cool-app' has copy command from 'my-cool-app/node_modules/react-native-wikitude-sdk/ios/WikitudeSDK.framework' to 'my-cool-app/ios/Build/Products/Debug-iphoneos/my-cool-app.app/Frameworks/WikitudeSDK.framework'
2) That command depends on command in Target 'my-cool-app': script phase “[CP] Embed Pods Frameworks”

How can I install and run my application on my device? I've tried about 100 different solutions from SO and other sources -- none have made a difference. Any help is appreciated.

Yes, something in your bundle is not being signed and is causing an installation failure. It looks like it is the path below but it's hard to say for sure:

my-cool-app/ios/Build/Products/Debug-iphoneos/my-cool-app.app/Frameworks/WikitudeSDK.framework

One way to figure out what is not being signed is to look at the signature on your exported build to disk. For example, on your main bundle and all of the embedded executables.

$ codesign -dvvvvv yourExecutable

In general I would contact your vendor about installation instructions for your framework, but TN2435 also would be a great reference to take a look at while you debug this issue.

  • Followed your advice and used the codesign utility, the WikitudeSDK framework executable is definitely not signed. However, the OpenSSL framework executable is also not signed. The thing is, the Wikitude framework is linked via Cocoapods -- pod install. Your reference link to TN2435 talks about adding the framework to "Frameworks, LIbraries, and Embedded Content" but I can't do that. The build immediately fails with the error above, since then multiple commands are trying to copy the framework. Is there anything else I could try? Perhaps adding a build phase to my project that signs the framework after its copied into place?

Okay, these frameworks will need to carry a signature though if they contain an executable.

Regarding:

I am not sure how Cocoapods set's up and loads your Frameworks into the Xcode project, but essentially you would need to get to a situation similar to the following:

  1. Create a new iOS blank Xcode project with the app template type.
  2. Create a new iOS Xcode project with the template type of Framework.
  3. Build the new Framework project and then take the built Framework and drag it into your new iOS blank project and set Embed & Sign.
  4. Build and sign the project from step 1.
  5. Check out the actual built results for your app, you will see the built and signed framework from 2 embedded into your iOS project.

Signing frameworks (pods) is required if you have added pods_****.framework and selected Embed & Sign, otherwise if you just add framework and select Do Not Embed it will not throw this error during installation on real device

  • I tried using embed and sign but still getting the same error

    Code: -402620388

    No code signature found.

    is there any other solution?
