swiftc-wrapper's Issues

Xcode crashing if no whole module optimization

Performing your workaround does not work if whole module optimization is turned off for the desired target. It does work when whole module optimization is on. I would update the instructions to mention this issue. It's probably a moot point since Xcode 7.3 will come out in the next few weeks, fixing this issue anyways. I really appreciate your workaround, by the way! Thanks so much!!!
