Swift: segmentation fault when compiling for Archive from iOS 7

Question

I've always had this issue so I started creating a new single-view application, in Swift, for both iPhone and iPad. When the target is iOS 8.1 everything works fine, but if I set iOS 7.1 (or 7), i get a Segmentation fault. This happens when i go to Product > Archive, when i Run the project in the simulator or my device, everything is fine. I tried with both iOS 7 and 8 simulators and it compiles. As I said, the problem is not in the code since it behaves this way even with a newly created project.

Does anybody have any idea about this issue?

UPDATE: I can target armv7s and arm64 to iOS 7, armv7 is what causes the issue; if armv7 is targeted to iOS 8 and others to iOS 7, everything works. That's not a good solution since it's more important to support older OSs on older devices, in my opinion.

Answer 1

I had the same problem until someone told me that it's a problem with the certificates. Go to the Dev Center and regenerate your Certificates & Provisioning Profiles. After that it should work!

Answer 2

Closing Xcode and opening another project, then loading back this one, solved the issue. It was a bug, I guess.
