Updating iOS for 64bit and SoundCloud

Question

I'm updating my iOS app for 64-bit. The app uses the SoundCloud API, which is not compatible with with 64 bit.

How can I work around this issue? Do I need to disable SoundCloud on 64-bit machines? How would one go about doing that?

Answer 1

Correct. You cannot link ARMv7 static libraries against an ARMv8 application.

The two options open to you are:

1. Produce separate 32- and 64-bit builds, in which the 64-bit build doesn't link against the sound cloud API library and associated UI features are disabled. This is doable, but a bit fiddly.
2. Ship only a 32-bit app. Ask yourself: is there really anything in your app that will be benefit from 64-bit compatibility? I suggest if not, you go for this option.

Note that ARMv8 capable iPhones and iPads are capable of running 32bit apps. There is a memory usage penalty in doing so in that both the 32-bit and 64-bit versions of shared libraries will be memory resident, but it's not a show-stopper.
