We do general Unix development on Mac OS X but because some of the libaries we link against are currently on 32 bit we have to produce 32 bit binaries.

When using Xcode 6 we can debug Unix binaries by selecting My Mac (32-bit) in the scheme selector, on Xcode 7 we only get My Mac and it gives the error: "the specified architecture 'x86_64' is not compatible with 'i386-apple-macosx' in '/usr/atc-5.00.5/dev/cust0400/xcust'.

I don't see any method of specifying i386 or 32-bit anywhere in build settings.

Thanks, regards, Rob.

Apple has been phasing 32 bit out over the last several years. In fact, there has been

no 32 bit mode in OS X since mountain lion. So, I don't think it a stretch that xCode 7

would drop support.

I was able to make a brand new OSX project in Xcode 7.1 and build it as 32-bit by changing only two build settings. Specifically Architectures (32-bit Intel) and Automatic Reference Counting (No). So it is still possible to do this. Getting your legacy project to build probably involves some build settings and scheme changes.
