Apple officially doubled the size limit for iOS applications. Going forward, App Store package submissions can carry a maximum size of 4GB. The new iOS app size limit marks a serous jump from the previously allowed 2GB. Apple’s cellular network app delivery size has remained unchanged at 100MB. A 4GB app size limit is surely going to benefit high-profile video game titles for iOS. Larger space allowed will result in more media and better graphics. The classic game BioShock for iOS is a great game example that can take advantage of the larger binaries. The current version of the game arrived on Apple’s mobile platform with scaled-down graphics in order to squeeze into the previous 2GB app size limit.

Apple brought two-step authentication to FaceTime and iMessage. The Cupertino giant has been using the feature for iTunes and iCloud accounts since 2013.

Going forward, iMessage and FaceTime users will need to enter a second security code after their user name and password. The code is sent via text to a registered device or to the Find My iPhone application.

By offering the beefed up security feature, Apple will make it more difficult for hackers to access iMessage and FaceTime accounts. The feature is commonly used by banks for accessing their online services.
