Checking for provisioning profile expiration

Question

Recently I shipped an enterprise app (distributed via HockeyApp) whose provisioning profile expired. As a result the app would not launch at all. No alert is presented to the user when a provisioning profile expires which is a very unfortunate situation.

Xcode warned me a few weeks before the provisioning profile would expire, so I renewed the profile and the warning went away. Unfortunately, I forgot to actually update the provisioning profile in Xcode’s build settings so I shipped an app that expired a few days after it was released.

I’d like to avoid this fiasco next year when the provisioning profile expires again. Is there something I can do to enforce checking that the provisioning profile doesn’t expire soon?

Answer 1

Here is a python script that will abort the build if the provisioning profile expires in less than 15 days. This script is meant to be run as a build phase script.

Note that this script will also work when run as part of an Xcode Bot integration.

#!/usr/bin/python

import glob, os, plistlib, subprocess, sys
from os import path
from datetime import datetime

def read_mobileprovision(mobileprovision_path):
    # From http://stackoverflow.com/questions/6398364/parsing-mobileprovision-files-in-bash/10490095#10490095
    return plistlib.readPlist(subprocess.Popen(['security', 'cms', '-D', '-i', mobileprovision_path], stdout=subprocess.PIPE).stdout)

if os.environ['PLATFORM_NAME'] != 'iphoneos':
    sys.exit(0)

provisioning_profiles_dir = '/Library/Developer/XcodeServer/ProvisioningProfiles' if os.environ['USER'] == '_xcsbuildd' else path.expanduser('~/Library/MobileDevice/Provisioning Profiles')
provisioning_profile_uuid = os.environ['EXPANDED_PROVISIONING_PROFILE']
mobileprovision_path = path.join(provisioning_profiles_dir, provisioning_profile_uuid + ".mobileprovision")
if not path.exists(mobileprovision_path):
    for mobileprovision in glob.iglob(path.join(provisioning_profiles_dir, "*.mobileprovision")):
        if read_mobileprovision(mobileprovision)['UUID'] == provisioning_profile_uuid:
            mobileprovision_path = mobileprovision
            break

print(mobileprovision_path)

expiration_date = read_mobileprovision(mobileprovision_path)['ExpirationDate']
print("Expiration Date: {}".format(expiration_date))

remaining_days = (expiration_date - datetime.now()).days
print("Remaining Days: {}".format(remaining_days))

if remaining_days < 15:
    sys.exit("error: Provisioning Profile {} is expiring in {} days.".format(mobileprovision_path, remaining_days))
