With the advent of handoff/continuity in OS X Yosemite, I was hoping there would be an API for this. I can't find one Googling. Alternatively, is there a way to open designated phone call making app like Skype to place a call? I've seen links on web pages to phone numbers that auto-open my Skype app. Is that the way to do it - with some HTML embedded in my Mac app?
You can use the same "tel:5555555555" URL syntax that you use on mobile platforms. So, for example to call the number 5555555555 you can do:
if let url = NSURL(string: "tel:5555555555") {
NSWorkspace.sharedWorkspace().openURL(url)
}
