SwiftUI List performance

In a thread on the older forums, one of the Apple engineers stated that the reason Float80 is only available on OS X and simulated iOS (not on iOS hardware) is because it isn't built in to the ARM processors.It doesn't sound like they are planning to put much work into Float80 at this point, if it isn't even going to to be availble on iOS devices. Since it It doesn't already have the right methods to conform to the protocol on OS X, it might not be worth the effort to them to make it conform.https://devforums.apple.com/message/1118295------------Swift's current design/policy for floating point types is to expose the capabilities of the processor. This doesn't preclude providing software floating point implementations of other floating point formats, but we cannot comment on future plans (or lack thereof) to add them.One thing I will point out though: Float is much more than just a space optimization. All modern hardware supports SIMD vectors, and using Float instead of Double enables 2x the auto-vectorization

This is at the top of my list as well! I have an app that has an enum with all of the countries and their country codes, and it isn't feasable to return a list of those by hand (it would easily get out of sync with the list and is a large amount of boilerplate).Here is the closest I have been able to come:protocol EnumerableEnum { static func allValues()->[Self] init?(index:Int) } extension EnumerableEnum { static func allValues()->[Self] { var idx = 0 return Array(anyGenerator{ return Self(index: idx++)}) } }If you have an Enum with integer values like so:enum TestEnum:Int,EnumerableEnum{ case A, B, C init?(index:Int){ self.init(rawValue:index) } }Then you can call the allValues() function to get a list of all values. If it doesn't have integer values, then you can implement the init method (but it doesn't buy you that much over just returning the list by hand).print(TestEnum.allValues()) // [TestEnum.A, TestEnum.B, TestEnum.C]A couple of notes:I couldn't ad

Yes I just noticed the flickering in the icon view too but I always use the list view.

About the dummy array + WKInterfacePicker, yeah I also figured that out. Thanks for the info about playing sound via bluetooth that might be interesting.Did you figure out how to respond to TAP events for the WKInterfacePicker? According to the docs:A WKInterfacePicker object presents a scrolling list of items for the user to choose from. Items in the picker may consist of text, images, or a combination of the two. The user interacts with a picker by tapping it, using the crown to scroll through items, and tapping again to select an item. A single interface controller may contain multiple pickers, each with its own set of items.

My ARD (3.8) allows control and observe, but I've noticed the following under 10.11:All of my previous machines and lists have disappearedIt prompts for my ARD password every time I launch the app, even if I tick 'Add to Keychain'Machines I add to the all computers list do not always appear with a blue dot next to them in the scanner to indicate they are already in the main listMachines that are in my list often show as simply 'screen sharing available', meaning I can't run any unix commands, reports etc. Quitting and relaunching ARD can sometimes cause this to change and result in me having full functionaility against a clientTested against 10.8 clients so far. Will test against 10.9-10.11 soon, but this will obviously not change certain things mentioned above.

I'm having the same issue. Items index without an error, but nothing gets returned in spotlight when I search for any indexed search term. Also, my app doesn't show up in the list of search providers in Settings (not sure if that is intended or not).Is there anything else we need to do to turn this on? I've also implemented the application:continueUserActivity:restorationHandler method in the app delegate.

iOS 9 battery usage by my measurements is reduced 62%. In addition overall performance is about 30% slower right now. I assume it's the beta build. iOS 8 was that way in the first couple of betas too.

This seems to be in conflict with the following statement by Apple:Get your apps ready with the latest beta versions of the San Francisco fonts for iOS 9,OS X El Capitan, and watchOS 2.Found here: https://developer.apple.com/fonts/I was able to download the fonts from the page above. So I am not sure about the source KMT's post and whether is is against the HIG or something for an iOS 9 app? It appears that the post from KMT is from here:https://developer.apple.com/watch/human-interface-guidelines/resources/And it looks like it pertains to resources for WatchOS downloads. But if you download the SF Fonts from the above link, then the Apple License Agreement with with files says this:APPLE INC.LICENSE AGREEMENT FOR THE APPLE SAN FRANCISCO FONTFor iOS and OS X application uses only---So it looks like you can use it with an iOS app and this article seems to confirm that:http://appleinsider.com/articles/15/06/12/apple-releases-san-francisco-system-fonts-for-ios-os-x-and-watchos-2-to-developersThe Font Tool Suite
