Replaces Xcode's project PRODUCT_BUNDLE_IDENTIFIER setting.
Replaces Xcode's project PRODUCT_BUNDLE_IDENTIFIER setting by passing in a new value.
This is the recommended way to substitute the bundle identifier
instead of modifiying the CFBundleIdentifier setting in the Info.plist file.
From Xcode 7 Release Notes: «The new build setting Product Bundle Identifier (PRODUCT_BUNDLE_IDENTIFIER) is the recommended place to set the Bundle Identifier for a target. The target’s Info.plist should be configured to use this build setting by referencing it as $(PRODUCT_BUNDLE_IDENTIFIER) in the value for the CFBundleIdentifier key.»
