64 bit coding required soon

[teacherguy]

Does this impact Livecode users?

Thanks

It will, but with LiveCode's success with 64-bit builds thus far I expect it won't be hard for them to meet the deadline for Apple's latest platform shift.

The bigger question is: Will Apple actually ship a mobile device with more than 4GB RAM?

A move toward 64 bit LC builds is most welcome, particularly given Apple's target date of 1 February 2015.

The downside is that Apps built for iOS below 5.1.1 cannot be 64-bit. This means we all have to consider the target builds very carefully from here on in. According to Apple, almost all iOS devices are running iOS 7 and iOS 8 nowadays so that may give a strong steer for us!

LC with 64-bit capability cannot come soon enough to help make this important transition smoothly with plenty of testing along the way.

To be clear, the Apple requirement is that from 1 February 2015 "...new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 9 SDK..." (Apple Developer News and Updates: 20 October 2014).

To meet this requirement, it looks like future versions of LC will need to build a single binary which incorporates both 32-bit and 64-bit code. As I understand it, this will still mean thorough testing for 64-bit.

This question came up on the use-livecode discussion list, where RunRev's LiveCode Product Manager, Ben Beaumont, provided an encouraging response:

Thanks for your question. We were made aware of this earlier in the week
and after reading the information available it seems we'll need to provide
a package with both a 32 and 64 bit version of the app. Compiling our
engine for 64 arm will be relatively straightforward so adding support for
this by February will not be a problem.

With only a couple of days left until Feb 1st ... what is the situation with LiveCode for 64bit iOS???

And just to mention: Apple grants another couple of months for updating already submitted Apps to 64bit. So Apps that have been approved in the past, must be provided in 64bit around June. New Apps have to provided in 64bit in 3 weeks!

Just submitted a new app to the store using LiveCode 7.0.1 and yes...got the "Missing 64-bit support - Beginning on February 1, 2015 new ...." email. Hmmmm wonder if it will get through.

So, am I doing something wrong or does 7.0.1 not support 64 bit yet? Can I use 7.0.2 RC 1? Not really happy about submitting an app with RC software.

Any ideas?

Cheers, Jeff from CleverInfo

64bit iOS builds was added to 7.0.2 (RC1) so please use this version when submitting to the iOS store.

We successfully built and re-uploaded our test app (Sheep Herder) via 7.0.2 and this approved by Apple without any issues

Kind Regards,

Thank you Neil,
1 quick question though. My build is being knocked back by the loader saying my chosen minimum iOS version in the prefs (which comes from the iOS standalone page in livecode) does not match the minimum for the two types of hardware. Tried all sorts of minimum iOS versions but keep getting similar errors.

What version did you use when you submitted? Thanks in advance

Cheers Jeff

64-bit/32-bit universal iOS 8.1 engines have been added in 6.7.2 and 7.0.2 (both are currently at the RC stage).
