Progress Report: iOS Auto Layout in Xojo

We continue to work towards Xojo support for iOS. Since the last update, we have been working on support for Auto Layout. We demonstrated Auto Layout at XDC last year. However, at the time we only had support for it in the framework; not the IDE. In case the term Auto Layout is unfamilar to you, it’s a technology for controlling the size and postion of controls. In Xojo today, you use the locking properties.

Instead of locking, you will use Auto Layout. Think of it as locking on steroids.

Is this a bug?
