I am confused by the code snippet following:
func foo(_ value: Int?) { // do nothing } let a: Int = 2 foo(a) // it works! Why swift don't warn the type mismatch? I am woking on Xcode Version 7.3.1. _______________________________________________ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
