Xcode 11.1 -no identity found Command PhaseScriptExecution failed with a nonzero exit code

Question

My project was working just fine. Last night I successfully uploaded a binary to AppStoreConnect. All of a sudden when I go to build my project I get this error:

Code Signing /Users/Home/Library/Developer/Xcode/DerivedData/ImStuck-...../Build/Products/Debug-iphoneos/ImStuck.app/Frameworks/Alamofire.framework with Identity iPhone Developer: Lance Samaria (52Q24UJ38T) /usr/bin/codesign --force --sign D0519CCxxxxxxxxxx --preserve-metadata=identifier,entitlements '/Users/Home/Library/Developer/Xcode/DerivedData/ImStuck-...../Build/Products/Debug-iphoneos/ImStuck.app/Frameworks/Alamofire.framework' D0519CCxxxxxxxxxx: no identity found Command PhaseScriptExecution failed with a nonzero exit code

I cleaned derived data and then I tried this answer and it didn't work.

It saying some number is missing:

D0519CCxxxxxxxxxx: no identity found

In the pic below the red bar is where the number is:

Answer 1

1. I went to Xcode > blue project icon > Signing & Capabilites and unchecked Automatically manage signing then checked it again to turn it back on

2. I went my developer account then went to Certificates, Identifiers & Profiles > Certificates > clicked each item then on the Download Your Certificate page I choose Download.

3. Once they downloaded I double clicked each one inside the downloads folder.

4. I found my original p12 certificates and keys then double clicked.

5. I went Xcode > Preferences > Choose my Team id then selected both Download Manual Profiles and Manage Certificates.

6. I went to Xcode > blue project icon > Signing & Capabilites and unchecked Automatically manage signing then checked it again to turn it back on

7. From there I closed the project, quit Xcode, and restarted my computer, restarted Xcode and pressed Build.

After everything booted back up the error went away.
