I've made a set of binaries and universal libs for the LDC iOS cross-compiler. It is based on LDC 0.15.1 (2.066) and LLVM 3.5.1.
https://github.com/smolt/ldc-iphone-dev/releases/tag/ios-0.15.1-150708 Only 32-bit devices currently; arm64 work starts next month when I acquire an iPhone 6. The download should have everything needed to run on an OS X build host in the same fashion as LDC downloads. But I may have missed something. Feedback appreciated. -- Dan
