No architectures to compile for (ARCHS=, VALID_ARCHS=armv7 armv7s)

Question

I am using Xcode 4.5.2 and have a project which cannot be compiled for an iPhone running iOS 6.0.1 though other projects compile fine with the same settings as shown in the picture below.

Any ideas on how to solve this?

Answer 1

You're probably using some third party lib that doesn't yet support armv7s architecture. You can just remove armv7s from your settings. Your app will still be able to run on iPhone 5 although it might not be taking full advantage of the new architecture.

Answer 2

If on XCODE 12 just goto Build Settings search for VALID_ARCHS. Under the User-Defined section select Valid Architectures and click Delete.

Answer 3

Set valid architecture for iOs simulator to armv7 and armv7s.( simulators are 32 bit ). for device set to arm64 (64 bit all new ios device).
