Google Cast SDK 2.5.0 missing required architecture arm64

Question

I'm trying to build an iOS app using Google Cast SDK 2.5.0 and am able to build on an iPhone 5 device, but when I try to build on an iPhone 6 device, I get the following build error:

ld: warning: ignoring file ./GoogleCast.framework/GoogleCast, missing required architecture arm64 in file ./GoogleCast.framework/GoogleCast (3 slices)

I noticed a post about a similar issue here: Google Cast SDK 2.3.0 for iOS doesn't support 64-bit

And so I tried this: ranlib GoogleCast.framework/Versions/A/GoogleCast

But I'm still missing arm 64. Has anyone had a similar issue?

Answer 1

As charmingToad mentioned in the comments, I had two versions of the Cast SDK being linked in my application. Removing the older version fixed the linking errors.

If you are using Cocoapods, all you need is a pod update to update your version of the Cast SDK.

If after upgrade Xcode is complaining about linker issues, adding -all_load as a compiler flag worked for me.
