Using an Unresolved WKExtension Identifier

Question

I want to make a phone call from Apple Watch. I imported WatchKit. Then I put this code in my method:

if let telURL=NSURL(string:"tel:[phone]") { let wkExtension=WKExtension.sharedExtension() wkExtension.openSystemURL(telURL) } 

This shows me an error: using the unresolved identifier "WKExtension" on line 2. I don't know what I'm doing wrong: /

Answer 1

WKExtension is only available on WatchOS 2.0, as you can see from the Apple preerelease reference . Therefore, I assume that you are either not using Xcode 7, or are working on the v1.0 clock extension.
