Apple quietly posted this announcement requiring all iOS developers to “Build Your Apps With Xcode 5.1.1″. Apple enforces this when you try to upload your binary to the iTunes App Store:
ERROR ITMS-9000: “This bundle is invalid. New apps and app updates submitted to the App Store must be built with public (GM) versions of XCode 5.1.1 or higher and iOS 7 SDK. Do not submit apps built with beta software.”
Today, we’ve addressed this in the last public release (2189). Just rebuild and submit. You can also use daily builds 2306 or later.
We allow Corona developers to also build for the Xcode iOS Simulator. Sometimes the simulator is preferable to our Mac or Windows simulator because the Xcode Simulator behaves more like a real device. Since we officially support the Xcode Simulator, we run our automated tests on the Xcode iOS Simulator to help verify our stuff actually works. While we could theoretically reuse the same process of scripting Xcode that we described in Part 2, we opted for a slightly different approach. As described in Part 2, Xcode 4 broke everything so we didn’t want to put this in the same critical path. Furthermore, Xcode 4 has some very nice speed improvements and reduces our build times to almost half. So instead, we simply use the command
Now that you’ve seen the overview of the whole system, I’m going to talk about on-device testing on iOS first because this has been where we have endured the most pain.
Preamble: This post is going to be a little different than usual. What we present here is behind the scenes stuff used in making the Corona SDK. But we hope the information presented here goes beyond satisfying simple academic curiosity. We hope this information will actually be useful for others to directly use in their own projects. And the target audience for this post goes beyond our normal demographic. In addition to Corona developers, we are also reaching out to all Xcode/iOS/Mac developers, all Android developers, all Lua developers, and anybody interested in automated testing/software reliability. Also, as a consequence of our solution, people interested in Applescript, Scripting Bridge, and/or LuaCocoa may also find things of interest. Because the topic is vast, not every single
