Open the workspace, not the project, if your app uses any CocoaPods plugins:

1. Create the watchOS app target

1

File → New → Target…

Select the watchOS tab → AppNext.
2

Fill in the target options

3

Activate the scheme

When Xcode offers to activate the new scheme, choose Activate.
4

Set the deployment target

Select the CarpWatch Watch App target → GeneralMinimum DeploymentswatchOS 8.0 or later.
Xcode creates a group CarpWatch Watch App containing CarpWatchApp.swift, ContentView.swift and assets; a target and scheme of the same name; and an Embed Watch Content build phase on the Runner target.

2. Bundle identifiers and signing

The watch app’s bundle identifier must be the iOS app’s identifier plus exactly one component: Xcode normally gets this right when you use Embed in Companion Application. Verify it under the watch target → Signing & CapabilitiesBundle Identifier, and check that the build setting INFOPLIST_KEY_WKCompanionAppBundleIdentifier on the watch target points at the iOS bundle identifier. Set the same Team on both targets and let Xcode manage signing. With manual signing you need a second provisioning profile for the watch app’s identifier.
If this relationship is wrong, watchOS never offers to install the companion app
The AWARE framework ships inside carp_aware_package as pre-compiled binaries. Xcode already resolved them along with the plugin, so all that is left is linking them into the watch target.
1

Select the watch target

CarpWatch Watch AppGeneral.
2

Add the framework

Under Frameworks, Libraries, and Embedded Content, press + and pick carp-aware-watch from the list of package products → Add
3

Leave it on Do Not Embed

The binaries are static libraries and require no embedding and signing
This results in two AWARE watch modules: com_awareframework_ios_sensor_applewatch_shared and com_awareframework_ios_sensor_applewatch_watchOS including the other packages they require.
Do not add carp-aware-watch to the Runner target. The iOS side of the plugin already links its own AWARE binaries through carp-aware-package. Adding the watch product to the app as well gives you two copies of the same modules and duplicate-symbol errors at link time.
