  • The Pittsburgh, Pennsylvania LiveCode Education Group held a recent meeting on August 24. We welcomed new member Cyril Pruszko, who is moving to the area. We discussed plans to offer opportunities to learn LiveCode in the region. Please get in touch with Claire Siskin, csiskin@edvista.com, if you would like to be involved in this initiative or to attend our next meeting.

New LiveCode releases

Since the week beginning 21st August 2017, LiveCode iOS apps are being rejected by iTunes Connect due to ‘invalid binary’. It turns out that Apple have upgraded the tools they use to analyse binaries, and this has shown an error in the Mach-O structure of the 64-bit slice. The version of otool with Xcode 6.x (on 10.9) does not show a problem, but newer versions do.

For this reason, we have built a new version of LiveCode 8.1.6 that addresses this issue.

So if you have already installed the original LiveCode 8.1.6 and are affected by this issue, please visit now


and download the latest 8.1.6 (STABLE), released on the 31st of August.

Notable changes

Bug of the week

In both of these reports, the reporters attached a simple and helpful sample stack, and provided a detailed recipe that helped us to test and confirm the problem quickly.

Help needed!
