App installation failed due to application-identifier entitlement

Question

I am unable to install a watchOS 2 WatchKit app due to an application-identifier entitlement. This happened after turning on App Groups in the Capabilities tab.

Answer 1

I had this problem with an iPhone app, and fixed it using the following steps.

• With your device connected, and Xcode open, select Window->Devices
• In the left tab of the window that pops up, select your problem device
• In the detail panel on the right, remove the offending app from the "Installed Apps" list.

After I did that, my app rebuilt and launched just fine. Since your app is a watchOS app, I'm not sure that you'll have the same result, but it's worth a try.
