Strange behaviour when export Application.cci vs XCode project

[AyreGuitar]

I'm getting different behaviour from my app on iOS than in MMF2 on PC when exporting iOS XCode project vs just Application.cci (possibly to do with ForEach object).
Not sure if this is something new in build 255 - beta 1.

After upgrading to build 255 - beta 1, I exported my current app to a new Xcode project, and carried on working, exporting Application.cci whenever I made changes. It was only yesterday that I noticed a bug that I thought I had fixed, re-emerge, namely to do with picking the topmost object using ForEach when another object overlapped.
So I went back to an earlier version and re-exported the Application.cci file for that into my new project - bug was still there. So I thought it might be a bug in new beta of iOS Exporter. Just to be sure, I re-exported my old version using beta1 and XCode project, bug was fixed!
So I re-exported my latest version as a new Xcode project and bug was fixed!

Perhaps the exporter has slight differences when exporting to XCode project or just Application.cci? I'd try to make a simple example, but exporting a fresh Xcode project seems to solve the problem, so can't see a way to do this. Perhaps I could email the 2 Application.cci files to Andos or Francois? I haven't checked to see if they're different, but I suspect so.

Lesson: If in doubt, re-export as XCode project!

(Edit: Can't seem to find the Application.cci that's buggy, so it might be a problem with XCode - possibly caching old files.)

I believe any time you update to a new beta, you need to re-export your MMF file as a new project. But from that point forward you can export only cci files. When a new beta is released, then you need to do another full project export again.

mobichan - I mustn't have made it clear enough in my original post that I did re-export my MMF file as a new XCode project zip file. I've not had this problem before and have been using iOS exporter for about a year now, so been through a fair few betas. Thanks anyway!

There is no reason for this : the application.cci is exactly the same in both modes.
The only thing I see, is that you use a new extension in the mfa, extension not present in the project (it will have no effect then)...

Francois - I think it might have been XCode caching something somewhere. By exporting a new XCode project zip file, it effectively clears the XCode cache. Very odd though!

Have a look in the Organizer -> Projects -> (your project).
From there you can delete the "derived data" which is all caches associated with the project. Clearing that will force a 100% fresh rebuild of your project as if it was exported from scratch.
