Debugging provisioning profiles on the command line
Raise your hand if you've ever struggled with getting your app's bundle identifier, info.plist, and entitlements.plist to match up with your provisioning profile.
I tried to explain provisioning profiles using the ten-hundred most common words, but in slightly-less-common words, a development prov-pro associates: A team, a developer, an application identifier, privacy and security entitlements, and development devices.
While there's no silver bullet, there is a way to dump the contents of a provisioning profile into a readable plist format. From the command-line, run:
security cms -D -i some.mobileprovision
Here, for instance, is the output of a provisioning profile for an app that uses SiriKit to trigger a workout:
As you can see, this is a convenient way to confirm the associations in the prov-pro, particularly entitlements, the app ID, and provisioned devices.
