Required code signature missing for a library

Question

I am using Swift 3.0 in Xcode 8 and facing this error when running my app. I have used third party library SlideMenuController.

When I run my app I encounter this error again and again but didn't found any solution.

Deleting derived data works some time but not always.

Answer 1

The following command in the Podfile helped me:

post_install do |installer|
    installer.pods_project.build_configurations.each do |config|
        config.build_settings.delete('CODE_SIGNING_ALLOWED')
        config.build_settings.delete('CODE_SIGNING_REQUIRED')
    end
end

Method 1

Add following code to your pod file

post_install do |installer|
    installer.pods_project.build_configurations.each do |config|
        config.build_settings.delete('CODE_SIGNING_ALLOWED')
        config.build_settings.delete('CODE_SIGNING_REQUIRED')
    end
end

Method 2

Perform following steps

1. Delete application from mobile or simulator (wherever you are facing this issue).

2. Select slideMenuController.framework in project navigator, right click on it, an click show in Finder. Open _CodeSignature folder and delete all files except CodeResources.

3. Close Xcode, open Terminal and enter the following command

   rm -rf ~/Library/Developer/Xcode/DerivedData
   

   This will remove all derived data from xcode.

4. Open XCode, clean and run application. Hopefully, problem will be resolved.

Answer 3

I had same issue with my mac10.12.5 & Xcode 9, There seems to be issue with existing data at derived data location SO better just remove your derived data either by :

XCode>Prefrences>Locations>click on arrow at Derived Data location & delete it.

or either by writing this command on terminal: Make sure your xcode is in application or you mention your xcode location :

rm -rf ~/Library/Developer/Xcode/DerivedData

Now Open XCode, run application. Hopefully, problem will be resolved. Good luck...

Answer 4

I am using the same library. Here is what I did to resolve the issue.

Find the SlideMenuControllerSwift.framework in your project folder/pods folder in xCode. Go to its location in finder.

Inside the framework you will find _CodeSignature folder. I had around 5 files in that _CodeSignature folder. Delete all except Code Resources file.

Clean build project and run.

Answer 5

I am experiencing the same issue with Xcode Version 8.0, having turned on the 'automatically manage signing' feature.

Other solution is:

Please see this issue: https://github.com/Carthage/Carthage/issues/1401

Second solution may be work for you.

Note: Please remove derive data from here ~/Library/Developer/Xcode/DerivedData

Answer 6

I've solved my issue with setting "ENABLE_BITCODE" to 0

Answer 7

I resolved it by setting a profile underneath Build Setting-->Code Signing Identity in my Framework project. My embedded Framework (the other framework within my own framework) is added to the Copy Files section in Build Phase.

hth!

Answer 8

Solved just by deleting the derived data and the app on the device. If that doesn't work try to toggle on/off the automatic signing.

Answer 9

I had this error when creating my own framework and update it by Pods.

I turn off Automatically manage signing and now it works good.

Hope it help you!

Just change the correct Xcode version you're currently running in Xcode preference / Locations.
