I don't know if you guys have heard, but starting with AIR 30 out in beta and due to be released soon, Adobe has just unexpectedly dropped support for 32-bit apps. They have only made one short statement claiming it is because MacOS is no longer going to accept 32-bit apps, but this is a horrible idea for mobile development. This will exclude iPad, iPad 2, iPad 3, iPad 4, and iPad Mini. If you have any existing 32-bit mobile apps in the app store, you will no longer be able to update them. You will have to make a decision to either stick with AIR 29 and never advance from there if you want to support 32-bit customers, or you will have to choose to deliver in AIR 30 or above but be unable to serve 30% of the mobile market who still use 32-bit apps. That is a LOT of customers to give up on! Heck, I still use a iPad 3!!!
All because of MacOS. Please go to this Adobe Forum thread and voice your concerns. SURELY there has got to be a way where they could give us a choice on how to deliver apps, that we as developers can be trusted to know what type of packaging we need to serve our own customers. I believe that they can make 64-bit the default, but there has to be a tag that can be added to ADT or something where you could choose to export as 32-bit, 64-bit, or both in your IPA. Please let your voice be heard, because this is happening fast!!! https://forums.adobe.com/thread/2486666 -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
