If it is checked, the developer profile will be imported into the existing keychain. If not checked, create a new key chain with the file name "jenkins-" + "job name" newly, and import the developer profile into this. (In this case, a random character string is automatically generated and used for the password) When importing developer profiles into a temporary key chain, please make sure that there are no duplicate certificates or private keys in the developer profile you import into the default keychain etc. If duplicate certificates or secret keys are included in both, Xcode gets confused and can not process the codesign correctly.
