SwiftUI List performance

I've created a new project with Xcode 7.0 which includes a Watch Kit app. I've updated my iPhone to iOS 9, and my watch to watchOS 2.0. I'm able to install version of my app by running the main app's Scheme and debugging on the device.However, if I want to debug on the watch I need to run the [App Name] WatchKit scheme. I'm unable to select my phone+watch though because they are listed under Inelegible Devices with the parenthetical explanation: (No symbols for paired Apple Watch)Anyone know how to get Xcode to download these symbols?

Just tried to pair MFi (Made For iPhone) Bluetooth hearing aids with an iPhone 6 running iOS 9 Beta 1. They show up in the device list under settings/general/accessibility/hearing aids, as expected, but the iOS controls for hearing aid volume etc. are not displayed. Looks like they are halfway paired. To the vendor supplied app (Kirkland Signature Choice), the hearing instruments are not present. This all worked as expected in iOS 8. Anybody with insight into this? All the other Bluetooth devices I previously had paired under iOS 8 appear to wotk fine. The only apparent issue is with the Bluetooth hearing aids, Of course, they are paired under the accessibility menu rather than the Bluetooth menu.

I cannot add any cards to Apple Pay. I get a message that says Could Not Add Card: Try again later or contact your card issuer for more information.I have tried with American Express, Mastercard, and Visa with same result, so I don't think card issuer is the issue.I did get e-mails from all of the above listed cards notifying me that the cards previously associated with iOS 8.4 had been deleted from my device, so it would at least appear that the cards are not somehow locked in the phone on the old setting. But I'm unable to add them back in.Any ideas?

It doesn't seem to be possible for me to debug on device wtih my apple watch. I can run my develpment app normally, but Xcode just can't seem to attach to a debugging session.I've read the relase notes and have tried:1) deleting the app/apps from devices and trying again2) ensuring Show App on Watch is on for dev app3) restarting all of: watch, phone, xcode, mac.4) unpairing / pairing againNo dice.When I click Run on the [AppName] WatchKit App scheme, the status window says Running [AppName] WatchKit App on [Phone name]. It stays like that for about 45 seconds. Then it says Finished running [AppName] WatchKit App on [Phone name].It really seems like the Phone->Watch connection is just way too slow. When I launch Xcode, it takes about 2 minutes before it considers my Phone+Watch pair as eligible for this scheme. During this initial 2 minutes, if I look into Window->Devices I don't see my watch listed even though I can clearly see it is paired.I'm going to turn this into an official bug report, b

My app supports Touch ID to allow the user to log in using a saved credential (password).When the user launches the app, they are immediately prompted to touch the home button to log in.A successful touch retrieves the credential and uses it to log in.We have been seeing sporadic problems under iOS 8.3.Upon launch the system will *not* prompt the user to touch, it will instead directly retrieve the correct credential and log in.I set the credential using the following code (some details shortened for readability):-(void)enrollTouchForUser:(NSString *)username { NSString *password = @passwordFromInterface; NSData *encodedPassword = [NSData encodePassword:password forUsername:username]; NSData *encryptionKeyData; // obtained from outside process - code not needed for this sample NSData *encryptedPassword = [NSData encryptDataWithKey:encryptionKeyData withData:encodedPassword]; // add the key to the keychain CFErrorRef error = NULL; SecAccessControlRef sacObject; // Should the secret be invalidated when passcode

Which model should I chose to download iOS 9 beta for my iPad A1430? It is not listed in the dropdown.
