Setting Xcode Build Settings Terminal

All Xcode settings is actually store in <project-name>.xcodeproj/project.pbxproj .It looks like

buildSettings = {    CODE_SIGN_ENTITLEMENTS = "";    CODE_SIGN_IDENTITY = "iPhone Developer";    "CODE_SIGN_IDENTITY[sdk=iphoneos*]" = "iPhone Developer";    ...    PRODUCT_NAME = "$(TARGET_NAME)";    PROVISIONING_PROFILE = "";    SKIP_INSTALL = YES;};

Code Signing Identity is controlled by CODE_SIGN_IDENTITY key and Provisioning Profile is controlled by PROVISIONING_PROFILE key.

The project.pbxproj is a text file that can be edited by traditional text processing tools in CLI, such as sed with

sed -ie 's/CODE_SIGN_IDENTITY = "iPhone Developer"/CODE_SIGN_IDENTITY = ""/g' <project-name>.xcodeproj/project.pbxprojsed -ie 's/PROVISIONING_PROFILE = ""/PROVISIONING_PROFILE = "1c28c979-6bef-4917-aa34-92aecd91315c";/g' <project-name>.xcodeproj/project.pbxproj

You can get the list of available Signing Identities with

security find-identity -v -p codesigning

For PROVISIONING_PROFILE, it's a UUID of provisioning file, it can be fetched with

grep -aA1 UUID /path/to/mobileprovision
