HI!
I've got an watchOS app that I would like to test. But when trying to install it from an iOS 11 device and a watchOS 4 first generation watch, I get the following error:
The screenshot says: "Couldn't install XXX on Apple Watch. Try again. [OK]". I found the following message in the log file:
… TestFlight(WatchKit)[15032] : -[SPDeviceConnection installApplication:withProvisioningProfiles:onPairedDevice:completion:]_block_invoke:426: installApplication for de.XXX.watchkitapp, withProfiles, failed with: Error Domain=ACXErrorDomain Code=19 "No WatchKit app is installed with the identifier de.XXX.watchkitapp" UserInfo={SourceFileLine=509, NSLocalizedDescription=No WatchKit app is installed with the identifier de.XXX.watchkitapp, FunctionName=-[ACXDeviceConnectionClient installApplication:withProvisioningProfileInfo:forTestFlight:onDeviceWithPairingID:completion:]}It's working fine on a second generation watch running the same software configuration or a first gen watch running watchOS 3.
Thanks
Christian
