[Update, 22 December 2015: The bug has been fixed by Apple in watchOS 2.1, the Glance will be returning in the next update to MacID for iOS and Apple Watch]
As you may have noticed, MacID’s Glance is missing from the native watchOS 2 app.
Removing the Glance was a very difficult decision, I spent time updating its design and only after then did I find a very frustrating bug with watchOS 2 which stops MacID for Apple Watch working if you open the app through the Glance.
What happens exactly, is if you launch the app through the Glance, the iOS-watchOS messaging APIs Apple have provided stop working and MacID for Apple Watch is no longer able to communicate with MacID for iOS. (Unless you press the digital crown and then go straight back into the app from either a complication or the app icon)
MacID for Apple Watch relies heavily on being able to communicate with MacID for iOS. Because we don’t have access to Bluetooth on the Watch, the iOS app maintains the connection and handles all the actions. When you tap a button to control your Mac on the Watch, it sends the command to the iOS app to carry it out.
You can see my post on the Apple Developer Forums, where one of Apple’s engineers forwarded on my bug report which got marked as a duplicate. This means they already know about the issue, and that it’s not just MacID that’s suffering from the issue.
As soon as Apple have fixed the bug I will re-add the Glance, but I couldn’t keep something in the app that I knew would cause such an issue. Thankfully, MacID’s complications work great and give you really quick access to MacID from the watch face.
