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. We determined early in the development of our iOS framework that locking would not be sufficent for iOS since the user will often radically change the size of the layout by rotating the device. Instead of locking, you will use Auto Layout. Think of it as locking on steroids.

Getting Healthcare.gov to Handle 50,000 Users

Healthcare.gov, the US Government’s health insurance exchange website for states that didn’t provide their own, was supposed to handle about 50,000 to 60,000 simultaneous users. Unless you have been living under a rock, you know what a complete disaster the website as been. But it didn’t (and doesn’t) have to be that way.

Building for Windows/Linux on Newer Macs

We have discovered what we believe to be a bug in OS X Mavericks specifically on newer Macs. Apple started using Intel’s new Haswell processor in the MacBook Air in June, the iMac in September and the MacBook Pro in October. When you build for either Windows or Linux from OS X, any images you dragged into your project are converted to BMP format. The bug we discovered (which we have reported to Apple – RADAR case 15546907) results in a banding of the converted graphic.

Writing High-DPI Aware Windows Apps

Today’s laptops and monitors support high resolution displays which allow you to pack more information and content on the screen. Although one common complaint is that people find the text to be too small at the maximum resolution, Windows’ solution to this is the ability for the user to adjust the DPI setting.

We are continuing to work hard on support for building iOS apps with Xojo. We believe Xojo will provide the easiest and fastest way to build applications for iPhone and iPad. Our focus so far has been on the underlying framework. The video below includes a demo of an iOS app we created in Xojo. I showed a small part of this app at the Xojo Developer’s Conference earlier this year.
