Prepare App

New Trio Builders¶

Create the `Trio App Group`¶

If you already have a Trio App Group

You can skip this step - your existing App Groups are found at this link: App Group List
If your Trio App Group was created from a Mac with Xcode, you may choose to edit the Description to make the NAME match

If you do not have a Trio App Group:

Go to Register an App Group on the Apple developer site and use the table below to help you create one.
Replace TEAMID with your Apple Developer ID.

NAME	Xcode version (NAME)	IDENTIFIER
Trio App Group	group org nightscout TEAMID trio trio-app-group	`group.org.nightscout.TEAMID.trio.trio-app-group`

Table of `Identifiers`¶

These are the Identifiers created by running the GitHub action "Add Identifiers". Only 3 of them need to have the Trio App Group added. The Trio Identifier also needs the Time Sensitive Notifications capability enabled manually.

NAME	Xcode version (NAME)	IDENTIFIER
Trio	XC org nightscout TEAMID trio	`org.nightscout.TEAMID.trio`
Trio LiveActivity	-	`org.nightscout.TEAMID.trio.LiveActivity`
Trio Watch App	XC IDENTIFIER	`org.nightscout.TEAMID.trio.watchkitapp`
Trio Watch Complication	XC IDENTIFIER	`org.nightscout.TEAMID.trio.watchkitapp.TrioWatchComplication`

Add Trio App Group to `Identifiers`¶

Open the App IDs Identifier page for your Apple Developer Account.
- Click on the Trio Identifier and assign the Trio App Group to the Identifier - see graphic below.
- Before saving the Trio Identifier, Enable Time Sensitive Notifications as described in the next section
- Repeat the App Group assignment for the other 2 Identifiers that need to have an App Group assigned: Trio Watch App and Trio Watch Complication

Enable Time Sensitive Notifications¶

There is one difference for the Trio Identifier compared to the other Identifiers. You must manually enable the Time Sensitive Notifications capability.

While editing the Trio Identifier to add the Trio App Group, keep scrolling down until you see Time Sensitive Notifications. Make sure that check box is enabled, as shown in the graphic below. Then tap Save.

This capability is only required for the Trio Identifier - you do not need to enable it for the other Identifiers.

Configure Trio App¶

Follow the directions in LoopDocs, but use the Trio Bundle ID

In App Store Connect, the Bundle ID for Trio will be: org.nightscout.TEAMID.trio

If you want to take it a step at a time, continue to Create Certificates.

If you are feeling confident, you can go straight to Build App which includes the create certificates step.
