İOS 26 beta battery %1

Check out Objective-C Language Features in the Xcode 7 beta Release Notes.Specifically:Lightweight generics allow you to specify type information for collection classes like NSArray, NSSet, and NSDictionary. The type information improves Swift access when you bridge from Objective-C and simplifies the code you have to write. (6294649) For example:NSArray<UIImage *> *images; NSDictionary<NSString *, NSURL *> *resourcesByName;

It has always been like that, but you could still downgrade like you could before... DFU and such.... nothing has changed.Hope this helps.AndreaEDIT:From iOS 8 Beta programDevices updated to iOS 8 beta can not be restored to earlier versions of iOS. Only registered development devices will be able to upgrade to future beta releases and the final iOS software.At the end of the day as long as the previews version is still signed you can downgrade without too many issues.

I use a few Exchange accounts with Apple Mail - its been a bumpy road over the last few releases in my experience. I don't know what the Mail team do but in some releases it works great and then it just stops working properly with Exchange accounts (read/unread not working properly, mail not automatically syncing, mail content not always appearing etc). So far in El Capitan I've been able to add one account - Mail seems fine with that but Calendar doesn't show the associated calendar even though I've made it active. Then when I add a second Exchange mailbox, Mail just crashes immediately and continues to do so until I remove the second account.

Same thing for me:I'm down to 59% after what iOS defines as:Standby: 2:41Usage: 1:56However, I'm not near the 2 hours of real usage, that the phone claims... So something is chewing up battery at a rapid pace. According to the stats, Home & Lockscreen is responsible for 30% of this.I did a real Restore and whiped the phone before restoring the backup, so Iäm not sure taht will help you a whole lot!/J

As as me. Here's the error log.Process: Mail [14455]Path: /Applications/Mail.app/Contents/MacOS/MailIdentifier: com.apple.mailVersion: ???Build Info: Mail-3054000000000000~1Code Type: X86-64 (Native)Parent Process: ???

Enrolling is completely broken for me. - For my Personal account I get always to the enter US ASCII accout information screen, once I fill out and accept, I'm there again with reset fields.- My Apple-ID is also associated with two company Dev-Programs which are still valid. Trying to download Xcode / iOS / ... just results in the login page displayed over and over.Summary: Flawed, and you're not alone.

Same here. Usage all came from Home and Lock screen for me. Have disabled the new Notification Centre widget for battery life in case that's the cause. Will need to keep an eye it to try and figure out what the culprit is.

But you can downgrade from iOS 9 beta 1 to iOS 8.3 oder iOS 8.4 latest beta.
