My iOS project's "Deployment Target" is "9.0" and build settings has following configuration: "Architectures = $(ARCHS_STANDARD) armv7s" and "Valid Architectures = arm64 armv7 armv7s". Is this sufficient for my app to support iPhone 4S, 5, 5C, 5S, SE, 6, 6 Plus, 6S, and 6S Plus running iOS 9 when distributed from Apple App Store?

Using the latest Xcode 7.3.1, build a sample app, your choice of template, Universal - check the architectures there for a current archs example string.
