Within two weeks of the release of the second beta version of its newest operating system - iOS 7 - to developers, Apple released the third beta of the software on Monday; with the latest update including fixes for pre-launch bugs in Messages, iCloud, AirPlay, and other features.

According to an AppleInsider report, citing the information shared by unidentified sources with knowledge of the iOS 7 beta 3 release notes, among the problems which have specifically been fixed in the latest beta version are the issues with the new iCloud Keychain feature, and problems linked to the Find My iPhone and Bookmarks toggles.

The iOS 7 beta 3 also brings about an improvement in the Messages application, which no longer presents an empty message list. In addition, another flaw which has been fixed is the one that led to the crashing of the app when attachments were viewed by users on two separate threads.

The AppleInsider sources also revealed that the beta 3 of the iOS 7 also enhances the app switcher which now shows all suspended applications; and updates a reportedly common problem that caused some apps to receive duplicate push notifications, or none at all.

Although beta 3 also addresses a number of other issues in the iOS 7, the AppleInsider report said that developers are still witnessing problems in a number of applications, including Contacts, Calendar, Notes, Passbook, and Safari, among others.
