Just recently I've run into errors while trying to install my app to my iOS 9 device, only difference that I can tell between now and then being I've updated my device to iOS 9 from iOS 8.4.1.
I'm installing using Xcode 7, beta 6, and the error I get says "App installation failed: Unknown error."
The, I suspect, more helpful error message I get is from the device logs during the install, the error message that seems to pertain to this is:
Sep 14 13:10:47 Bill-Luhmanns-iPhone installd[50] <Error>: 0x16e1bb000 -[MIExecutableBundle hasOnlyAllowedWatchKitAppInfoPlistKeysWithError:]: 1033: WatchKit app has disallowed Info.plist key: CFAppVersion
Then there are a handful of other logs that give the same message from different areas.
Any ideas how I can get the target to allow that key in the plist file? I've checks that the file is in the right place, that the key exists, etc. etc. As a last ditch effort, I've deleted my derived data and restarted both mac and device, all to no avail. Cleaning the project also didn't help.
Any suggestions or ways to fix this that anyone is familiar with? I'd really appreciate it, thanks!
It's saying the info.plist associated with your watch kit app has an invalid key - CFAppVersion. I think you'll discover that deleting that key from your watch kit app's info.plist will fix your build issue.
