iOS app testing. App installation failed. No code signature found [closed]

In my case, the problem was unsigned frameworks.

Xcode 11 or above:

Go to Build Phases, expand Embedded Frameworks and select all Code Sign on Copy checkboxes.

Xcode 10 or earlier:

Build Phases > Copy Files > Code Sign on Copy (select all checkboxes)

I had this problem, this is what I did to resolve it:

Run "clean" in Xcode
Close Xcode
Remove all data in ~/Library/Developer/Xcode/DerivedData
Remove all xcuserdata folders in your project (check in your xcodeproj and project.xcworkspace directories)

Only if you have Cocoapods in your project:

Now you can open your fresh Xcode.

Hope this help you.

In my case the problem was created by adding a new cocoa touch framework.

If "code sign on copy" fails, then check if you are modifying the frameworks in a run script after the "Embed Frameworks" phase.

If you are, then move the Run script to a position before the "Embed Frameworks" phase.
