Ios – Xcode 10, Command CodeSign failed with a nonzero exit code

iosxcodexcode10

Everytime I build console is showing this message.

CodeSign /Users/admin/Desktop/AppStoreBuild/Project201/build/Debug-iphonesimulator/Project.app (in target: Desker)
cd /Users/admin/Desktop/AppStoreBuild/Project201
export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate

Signing Identity: "-"

/usr/bin/codesign --force --sign - --entitlements /Users/admin/Desktop/AppStoreBuild/Project201/build/Project.build/Debug-iphonesimulator/Project.build/Project.app.xcent --timestamp=none /Users/admin/Desktop/AppStoreBuild/Project201/build/Debug-iphonesimulator/Project.app

/Users/admin/Desktop/AppStoreBuild/Project201/build/Debug-iphonesimulator/Project.app: resource fork, Finder information, or similar detritus not allowed
Command CodeSign failed with a nonzero exit code

…
Is there any way to identify the cause of this failure. It's showing Signing Identity: "-" when I try to run in simulator also. why do we need signing identity in simulator. And one more thing is if I quit Xcode and restart, it will build properly when I change code or add a method will again build failing.

I had that problem and Xcode failed to compile on the device, but on simulator, it worked fine.

I solved with these steps:

  1. Open keychain access.
  2. Lock the 'login' keychain.
  3. Unlock it, enter your PC account password.
  4. Clean Project in the product menu.
  5. Build it Again.

And after that everything works fine.
