Testing 32 bit iOS app on iPhone 5s or 64 bit simulator

Question

I have an app that uses a third party library. There is a bug in the 64 bit version of the library so I had to revert to the 32 bit version of the framework. I would like to test this release on a 5s but from XCode it will try to build in 64 bit and because of this 32 bit framework the build will fail. I need to release a version but since I'm unable to test on the 5s or 64 bit simulator I'm reluctant to do so. So it there any way to get the app on the iPhone or run it on the 64 bit simulator without having to build the 64 bit version?

The iPhone is provisioned and I've used it for testing the 64 bit so it is not an issue.

Thanks in advance

Answer 1

In Build Settings, change Architectures to $(ARCHS_STANDARD_32_BIT).

Then choose iPhone Retina (4-inch 64-bit) for the simulator.

It will build a 32 bit version of your app but run it on the 64 bit simulator. Note that the simulator is running on OS X and OS X doesn't support 32 bit anymore, so we have always been running 32 bit apps on 64 bit hardware in the simulator. It works fine, as long as you don't need some types to be 64 bit (eg: CGFloat is accurate to significantly more decimal places when complied for 64 bit).
