SwiftUI List performance

From what we can see, the linker accepts the TBD file as effectively a list of symbols to presume are defined in order to allow compilation - if you add that file to the linked frameworks of your project, it will no longer generate errors for the missing symbols.edit: removed conjecture due to issues we were also having. Just link to the TBD file and it should work.

As with several others in this thread, whenever I try to select an IOS 9 device via the little device iconon the iTunes button bar, iTunes freezes.Following some suggestions here and elsewhere I have tried the following:Find my Phone/iPad both on and offBackup and Sync via the menuDeleted all prior backups, then backup and sync via the menu againDeleted SyncServices folder, then restarted iTunesInstalled latest xCode betaNone of the above made any difference.One thing to note, if the device dropdown shows the device names, you can eject them from the dropdown and sometimes, if you are lucky, select them. If the device name is not shown and the dropdown lists only generic device types, such as iPhone or iPad, then you are SOL and iTunes will hang no matter what.All of the above occurred with any IOS 9 device, Beta 1 or Beta 2, connected to iTunes 12.x.x on both OS X 10.10.4 Beta 4 and 10.11 Beta 2.

It's true that this is the case for the DP2 update itself. This is why I haven't dared to try that yet. But I'm not convinced about Command Line Tools having 2 packages. After installing the CLTools_Executables.pkg the Command Line Tools update actually disappeared from the App Store Available Updates list. If it wasn't installed completely then wouldn't it still be in the updates list?

Just to report here I'm getting the same error in iOS 9 (both beta 1 and 2):*** Assertion failure in -[YCTableView _endCellAnimationsWithContext:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3480.5/UITableView.m:1362 attempt to perform a delete and a move from the same index path (<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0})

There seem to be a few issues with Disks for EC so far. Startup manager is mostly non functional for me. I have 3 bootable partitions and all three show. However only the EC one works, the other two end up in EC as well.Even when booting using the Command key the same thing is true. They list differently there, but still same result.What is really odd is what makes them begin to work. Make a bootable install thumb drive with some version of OS X on it (doesnt seem to matter). Power down the mac and insert the thumb into the hub. Power up and use Command key, then all partitions show, including a recovery for each bootable partition, and they work correctly. Then the other bootable partitions work. More so, you can use the regular startup manager within OS X to boot between the other two. But one you return to EC, the incorrect cycle repeats.

Agreed with others here. My battery performance had probably halved on my iPhone 6+ and Watch with the first betas of iOS9 & Watch OS2 but beta two has probably recovered around half of what I had lost in performance. Would be more likely to recommend it as a beta now.

I use osX Yosemite 10.10.3, its not beta.Two months ago i already submitted other app with no problems, and now im stucked with this problem.The error message appear when 'Fetching list of teams from the developer portal...'.

We're getting a bit of topic here, but if you can't install and you can't restore, you could try booting into Single User Mode:Hold down Command and S keys at bootup for 10 secs or so. Wait until the command-line prompt appears (after all the text is done scrolling past.) Then type fsck -fy and press Return. Eventually, after five different checks that take varying amounts of time, you should get to one of two messages: The volume [your Mac's name] appears to be OK or FILE SYSTEM WAS MODIFIED. If you encounter the first message, type reboot and press Return. If you see the latter message, though, you'll want to run fsck -fy all over again. You can retype the command and hit Return, or press the Up arrow once and then press Return.If that doesn't work you can also erase your El Capitan partition in SUM and try again.Finally, if all else fails, you can restore to your original OS X with Internet Revovery mode:Boot to the Internet Recovery HD:Restart the computer and after the chime press and hold down the COMMA

What do you mean by download?If you mean the number of accounts that have purchased your application (even free applications get purchased) then that's listed as sales, whatever the user's iOS version is. Updates, installs, reinstalls, etc. are messy stastics to try to figure out from the sales reports, but that'll be all you have to work with.If you mean the specific data like number of times installed/reinstalled from the store as provided for iOS 8, then you're going to have to accept a whole lot of That information isn't available for previous versions. There are a lot of pieces to the analytics software, and some of those pieces just aren't present on the iOS 7 devices.
