Converting my app to use Swift 2, and I'm getting a crash on this if-let where clause (that worked in 1.2):Used to look like this:if showFilterButton { if let dataController = dataController() as? FilteredCoreDataController, filter = dataController.filter where filter.customized { filterButton = UIBarButtonItem(image: UIImage(named: FilterFilled), style: .Plain, target: self, action: showFilters:) } else { filterButton = UIBarButtonItem(image: UIImage(named: Filter), style: .Plain, target: self, action: showFilters:) } } else { filterButton = nil }But it crashes on line 2. Finally discovered that removing the where clause doesn't crash the app (but obviously doesn't give me the behavior I want). Thought it was something weird like Apple changing how where clauses with in an if-let clause, but even separating it out into a nested if doesn't work:if showFilterButton { if let dataController = dataController() as? FilteredCoreDataController, filter = dataController.filter {//where filter.customized { if

As a heavy user in Chinese text editing, I used to have 3rd-party input method with Shuangpin happily on the jailbroken iOS7 device.Nowadays, iOS8 has all the major Chinese input method corps, like Baidu and Sogou, without the API toward bluetooth keyboard.As a result, my productivity dropped dramatically without a BT keyboard, so were a lot of heavy users in Chinese world. And the answers were all pointed to the limitation of SDK.Hence, I sincerely wish Apple to empower 3rd-party developer the access to BT keyboard.With the mighty power of BT keyboard and 3rd-party input method, the productivity of iPhone and iPad will be fully unleashed in Chinese text editing field.

I have the Watch 2 Beta 1 profile installed on both my iPhone and Apple Watch. I downloaded the update through the Apple Watch app, but when it goes to install it says it failed to install. Both the watch and iPhone are fully charged and plugged in, and both have been restarted. Any ideas?
