PostSubject: Apple Releases iOS 5.1 Beta 1 For Developers, Complete Change Log, Download Now    Wed Nov 30, 2011 2:14 pm

Apple has just pushed iOS 5.1 Beta 1 for iPhone 4, iPhone 4S, iPhone 3GS, iPod Touch 4G, iPad 1 and iPad 2 to their registered developers. A lot of iPhone 4S owners were experienceing massive battery drainage issue in iOS 5, this issue was not limited to iPhone 4S users only, iPhone 4 and other iOS devices running iOS 5 reported about battery drainage issue. Apple released iOS 5.0.1 to address this issue but it wasn’t resolved in iOS 5.0.1 update.













iOS SDK 5.1 provides support for developing iOS applications and includes the complete set of Xcode tools, compilers, and frameworks for creating applications for iOS and Mac OS X. These tools include the Xcode IDE and the Instruments analysis tool among many others.




With this software you can develop applications that run on iPhone, iPad, or iPod touch running iOS 5.1. You can also test your applications using the included iOS Simulator, which supports iOS 5.1. There are two Xcode iOS SDK 5.1 images, one for installing on a Macintosh computer running Mac OS X 10.6.7 (Snow Leopard) or later, the other for installing on a Macintosh computer running Mac OS X 10.7 (Lion).



This version of iOS is intended only for installation on devices registered with Apple’s developer program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.

iOS 5.1 Beta 1 is not a public release which means only registered Apple developers can download iOS 5.1 beta 1 right now. iOS 5.1 beta will definitely address battery drainage issue in iPhone 4S, iPhone 4, iPhone 3GS and other iOS devices.

iOS 5.1 Jailbreak Information:



Jailbreakers are requested to stay away from iOS 5.1 update. No jailbreaking tool has been updated to jailbreak iOS 5.1 untethered or tethered right now. We will update you about iOS 5.1 jailbreak as soon as it comes out.


Download iOS 5.1 Beta 1 IPSW:



As this is not a public release this beta update will only be available for registered Apple developer. Apple developers can download iOS 5.1 IPSW firmware files from Apple Developer’s Portal.

iOS 5.1 Complete Change Log:





Introduction




iOS SDK 5.1 provides support for developing iOS applications and includes the complete set of Xcode tools, compilers, and frameworks for creating applications for iOS and Mac OS X. These tools include the Xcode IDE and the Instruments analysis tool among many others.

With this software you can develop applications that run on iPhone, iPad, or iPod touch running iOS 5.1. You can also test your applications using the included iOS Simulator, which supports iOS 5.1. There are two Xcode iOS SDK 5.1 images, one for installing on a Macintosh computer running Mac OS X 10.6.7 (Snow Leopard) or later, the other for installing on a Macintosh computer running Mac OS X 10.7 (Lion).


This version of iOS is intended only for installation on devices registered with Apple’s developer program. Attempting to install this version of iOS in an unauthorized manner could put your device in an unusable state.

iOS Developer Program - Apple Developer

Bug Reporting



Please report any bugs not mentioned in the “Introduction” section using the Apple Bug Reporter on the Apple Developer website (Bug Reporting - Apple Developer). Additionally, you may discuss these issues and iOS SDK 5 in the Apple Developer Forums: http://devforums.apple.com. You can also access more information about iCloud for Developers at: http://developer.apple.com/icloud


Notes and Known Issues



The following issues relate to using the 5.1 SDK to develop code.

Accounts



When creating an iCloud account, you can use any Apple ID as long as it is a full email address and not a MobileMe account. If you have a MobileMe account, you can move that account to iCloud. You can find more information at: http://me.com/move

APIs




  • The NSNetService class and CFNetService APIs do not include P2P interfaces by default. To browse, register, or resolve services over P2P interfaces, an application needs to use the Bonjour DNSService*() APIs noted below.

  • Setting the interfaceIndex parameter to kDNSServiceInterfaceIndexAny in the following API’s will not include P2P interfaces by default. To include P2P interfaces, you must now set thekDNSServiceFlagsIncludeP2P flag when using kDNSServiceInterfaceIndexAny or set the interfaceIndex to kDNSServiceInterfaceIndexP2P. The affected APIs are:
    • DNSServiceBrowse
    • DNSServiceRegister
    • DNSServiceResolve
    • DNSServiceRegisterRecord
    • DNSServiceQueryRecord
GameKit




App Icons and Profile Photos are not loading in apps using Game Center.

iCloud Storage



  • Provisioning profiles must be enabled for iCloud in the iOS Provisioning Portal. You can enable a provisioning profile for iCloud by navigating to the App ID section of the iOS Provisioning Portal and configuring your App ID for iCloud. After enabling the App ID for iCloud, regenerate your provisioning profiles to enable them for iCloud.

  • The setSortDescriptors: method of NSMetadataQuery is not supported.

  • In iOS 5, files that are protected via Data Protection cannot be used with iCloud Storage APIs.


  • File names are case-insensitive in Mac OS X but case-sensitive in iOS. This can lead to problems when sharing files between the two using iCloud. You should take steps on iOS to avoid creating files whose names differ only by case.

Movie Player



Starting in iOS 5.0, in order to facilitate finer-grained playback control, a movie player is not automatically prepared to play upon creation. Call the prepareToPlay method to prepare the movie player. For more information, see MPMoviePlayerController Class Reference

Music Player




Using shake-to-shuffle causes Music app to freeze and playback to stop.

Newsstand



FIXED: Deleting an issue that was marked as the currently reading issue could cause a crash.

Security



In iOS 5, the signing of certificates with MD5 signatures is not supported. Please ensure that certificates use signature algorithms based on SHA1 or SHA2.


Xcode/Developer Tools



  • A bug in the documentation organizer causes an exception when you type in any field in the content area. To prevent the need to log in to the developer website from Xcode, download documentation sets locally using Xcode’s documentation preference pane and enable the ‘Check for and install updates automatically’ checkbox as a workaround.

  • “uninstall-devtools” script mistakenly removes files and packages even if Xcode is still running. Be sure to quit any running copy of Xcode before starting the “uninstall-devtools” script.

  • The Network Link Conditioner daemon cannot be launched after installing the Networking Link Conditioner without a reboot. You can manually workaround the issue with a restart or by the following command: sudo launchctl load /system/library/launchdaemons/com.apple.networklinkconditioner.plist.]

  • In the iOS 5 development tools, it is possible to extract APIs used by an application and have them checked for use of private APIs. This option is offered when you validate your application for app submission.

We will keep you updated on this, stay tuned!

iOS 5.1 Beta 2 has been released to Apple developers today from the developers page of Apple's Web Site. The build number of his iOS version is 9B5127c and it supports every iOS 5 device.

The update doesn't appear to come with any amazing new features however it carries over some updates from iOS 5.1 Beta 1 (found and reported by 9to5Mac) such as:
A "geofencing" setting that can help stop battery drain with the Reminders app when you're not using it.
There is now a 'Use Cellular Data' option to sync iTunes Match music in the iTunes Match settings.

Nothing out of the ordinary – just some minor bug fixes and tweaks. If we find anything else in iOS 5.1 Beta 2 we will keep you posted!

One thing to note is that iOS 5.1 is coming and its right on the horizon. The Chronic Dev Team's untethered jailbreak will work for iOS 5.0 and iOS 5.0.1 users but iOS 5.1 will likely not be included. We recommend that the Chronic Dev Team holds off until iOS 5.1 is released to see if it will work on iOS 5.1 and if it does not then just release it for the older firmwares. iFaith provides a viable option for ALL users to get back on iOS 5.0 or iOS 5.0.1 if they need to so there are no excuses.
