A starter bug for someone who wants to dip their toes into the Swift compiler: SR-2875 Emit objc_allocWithZone(cls) instead of [cls allocWithZone:nil] https://bugs.swift.org/browse/SR-2875
swiftc currently emits calls to [cls allocWithZone:nil] when constructing Objective-C objects. It should emit calls to objc_allocWithZone(cls) instead. objc_allocWithZone() is faster (it avoids a message send when there are no overrides in place) and is a smaller call site. I believe the code to change is getAllocObjectFormalType() and emitObjCAllocObjectCall() in swift/lib/IRGen/GenObjC.cpp. Not interested in this bug? We have dozens of other bugs marked "StarterBug" that we expect to be suitable for someone who has not contributed to the Swift project before.
