Fix no matching provisioning profiles validation issue

Here’s a quick problem & solution that worked for me. Hopefully this helps others out there.

Situation:

Validating an archive prior to submitting the build to the App Store, but it fails validation. I am using App Groups (for the phone app & watch app).

Problem:

Validating my archive created two “no matching provisioning profiles found” errors. The error was specifically related to “none of the valid provisioning profiles allowed the specified entitlements betareports-active com.apple.security.application-groups”.

Solution:

In my case, my development was able to use App Groups, but the production/distribution environment was not setup yet.

Under Provisioning Profiles > Distribution (https://developer.apple.com/account/ios/profile/), create an Distribution / App Store for each App ID that you need. In my case, I had to create one for the phone app & one for the watchkit extension. Make sure to download each after generating them. Double click on your downloaded files to automatically load them into Xcode.

When I tried to validate my archive again, I was able to successfully validate (after generating & loading my new Provisioning Profiles).

Standing on the Shoulders of Documentation

sprout123

Learning how to build a simple iOS app has not been bad. There’s a lot of learning how to find things in Xcode (protip: get a 2nd screen) and familiarizing myself with UIKit conventions. I completed the bitfountain iOS 7 course and have subscribed to more iOS newsletters than I care to admit.

At a meetup last year, I had a discussion about my choice to start with Objective-C. He asked me why I didn’t jump into Swift or use a tool like PhoneGap. Fast forward several months to today, I’m very happy I went with Objective-C. Whenever I am unsure how to do something in Objective-C, there are endless helpful blog posts and StackOverflow discussions out there. Even blog posts written before 2010 can be helpful. I am truly standing on the shoulders of all those heroic individuals who’ve tread down the path before me years ago.

With Swift, I’m sure there’s great documentation out there, but my guess is that Swift today (the beginning of 2015) cannot compete with the thoroughness of Objective-C edge cases discussed on the Internet.

Access to simple, basic questions like converting a NSUInteger to a NSNumber are essential for those just starting out. I’d like to use the example of an extremely beginner friendly resource, RailsCasts, which taught you how to use run of the mill gems, like Devise, and helped create a new generation of developers. Without a wealth of beginner accessible resources, a language or framework can’t grow or grow as fast.

iOS Programming

I’ve started learning iOS programming. Objective-C seems very low level, but it’s alright as an older object oriented language. Learning the Apple frameworks seems to the be tricky part. There’s a lot for me to learn with using Xcode (since I don’t normally use IDEs) and frameworks like Cocoa Touch.

I spoke to someone recently who suggested skipping Objective-C and going directly to Swift. Or even a tool like PhoneGap. Personally, I side with Aaron Hillegass’ take:

I have three messages for these people:

  • If you want to be an iOS developer, you will still need to know Objective-C.
  • Objective-C is easier to learn than Swift. Once you know Objective-C,
  • it will be easy to learn Swift.

To take a longer perspective on iOS, I want to build my foundation up from Objective-C to iOS. This is similar to how learning Ruby is critical for being a Rails developer.

With that said, I’m eager to get my hands dirty with iOS prototypes through different online courses.

iOS Simulator

When previewing a site on my iPhone (1136 x 640), I wasn’t satisfied with using my iPhone 5 or a Chrome browser Window Resizer app.

Turns out it’s super simple to use the iOS Simulator with Xcode on OS X (version 10.8.5).

Select Xcode > Open Developer Tool > iOS Simulator

xcode

You’ll be presented with an iPhone to navigate within. Select Safari and you can use a site like localhost:3000 for development.
