Fix Browser Build for v5.1

[dnzxy]

Fastfile additions and changes:

• Change bundle ID and target for Watch Complication Extension
• Change bundle ID and target for Watch App
• Change bundle ID and target for Widget Extension
• Resolve packages
• Update Testflight.md

Successful workflow runs can be found here:

• Add Identifiers (extend-fastfile)
• Create Certificates (extend-fastfile)
• Build xDrip4iOS (extend-fastfile)

This update (and the changes to the project bundle IDs and build with v5.1) will requires users to

• run Add Identifiers action
• go to the Apple Developer website and re-configure the app group for the 3 com.TEAMID.xdripswift.<other-ids> bundle IDs, namely
  • com.TEAMID.xdripswift.watchkitapp.xDripWidget
  • com.TEAMID.xdripswift.watchkitapp
  • com.TEAMID.xdripswift.watchkitapp.xDripWatchComplication
• run Create Certificate action before they are able to build again.

Since the build target for the Watch App was changed but the bundle ID was kept, it may be necessary to remove the existing Watch App identifier and associated Provisioning Profiles before running Create Certificates. I had to do that, or else matching failed.
