Version 4.1.51 (15S2126s) is Server 5.0 Beta 1Not the first time Apple have done a beta version where the version number on the application shows as if it was a newer version of the previous version. They are not big on having version numbers show as 5.0b1.

In a simple version, any two objects which are not the same class could just return false and if they were the same class could do something like the current Equatable method.But sometimes two values that are semantically equal are not the same type:let myInt = 2 let myDouble = 2.0 myInt == myDoubleMaybe you could special-case numeric types, but sooner or later somebody would make the same mistake with different types. It might be 2 and 2, or it might be a String and an NSAttributedString, or it might be a Product and a ProductID. But whatever it was, somebody would write some code they expected to work, and then they'd be surprised when it didn't.Swift is designed to prevent these kinds of problems. So Swift's designers recognized that, actually, there's something a little funny about comparing two values of different types. Iftwo values can never be equal, why are you testing whether they're equal or not? That doesn't really smell right; you're probably doing something wrong. Let's just make the compiler fl

Yes, but it doesn't really tell anything explicitly about this particular use case (iterating over a collection of enums with associated values, and only over the ones that matches a particular member value, getting a copy of the associated value from each of them).The closest thing on that page (and in the iBook) is this example:let arrayOfOptionalInts: [Int?] = [nil, 2, 3, nil, 5] // Match only non-nil values for case let number? in arrayOfOptionalInts { print(Found a (number)) } // Found a 2 // Found a 3 // Found a 5Yes, number? is short for .Some(number), but using the special ?-form also hides the more general form of the pattern. The example is focusing on the special case of Optionals which is fine, but it also obscures the general pattern. And I don't think most people will quckly deduce this from that example or by analyzing the grammar.Perhaps there should be some additional example using the pattern in question, ie:for case let .Foo(value) in enumValues { ...Especially if the syntax in the WWDC 201

Now I've been able to run my iPhone 6 128GB with iOS 9 beta 1 for 40 minutes straight in standby mode (just viewing some e-mails from time to time, mobile data enabled, all background stuff disabled with not even 1% loss on the battery. Battery saving mode is also disabled. Don't really know what I did.. All I did was viewing the log files through the device viewer in Xcode. Disconnected the cable after a while and ended up where I'm now.. Before viewing the logs in Xcode I rebooted the phone also. But I did not change any settings in the phone from where it was before so I don't really understand what's going onSoon it's actually 50 minutes without any battery loss.. still at the 97% as it was when I disconnected it from my Mac. Seemingly the background activity going on before on the home screen also suddenly stopped.I'm going to spend my weekend looking into this matter a bit deeper, just for the pure fun of it

Could it relate to this note in the release notes?On pre-2009 Macs, Bluetooth may sometimes not show up after reboot or wake from sleep. Reboot the system to workaround.

It is not possible to pair an Apple Watch with OS 2.0 and an iPhone running 8.3. I just tried it 🙂

Well, you probably missed the keynote. One new feature is a way better energy management. Thats great news since they bring the lessons learned from the watch over to iOS.Ask your self as dev - is implementing a feature like this done with just typing code and run it once in the simulator? Nope, it needs fieldtesting.Welcome to the beta.As for our testequipment it seems to apply only to devices that are known to benefit the most from this feature. iPhones 6 as the only devices eating their battery. Thats cool, because deep discharge once in a while helps the battery to live longer.// running gagGlad you didn't install the beta on a device you use everyday, aren't you. 🙂// jedes Jahr das gleiche 😀
