New Lister app error "The shared application group container is unavailable. Check your entitlements and provisioning profiles for this target..."

Question

I've done everything in the Read Me.

Still after I press play, Simulator runs then crashes with this message:

Failing at line 175:

let toURL = ListUtilities.localDocumentsDirectory.URLByAppendingPathComponent(url.lastPathComponent)

I have no idea what to do.

Answer 1

You have to change the LISTER_BUNDLE_PREFIX to your company bundle ID, like "com.yourcompany.com", and eventually fix the error in App Group option and iCloud option. The first step must be done before step 2 & 3.

1. First, change the LIST_BUNDLE_PREFIX in project Setting. You find this setting in the "Build Setting" tab of your project (not a target) !!!

2. Fix App Groupe

3. Fix iCloud option
