Int.min is the smallest negative value, and Int.max is the largest positive value (that fits in an Int). However, the absolute value of Int.min is larger than the absolute value of Int.max. So you can't convert Int.min into -Int.min because it's larger than Int.max. In other words, this is expe

Greg, This occurs when compiled with swiftc -g as well. In fact, I think 'swift build', when run by default, will compile with swiftc -g. It's only when you run 'swift build --configuration release' that it will compile without it. $ swiftc --version Apple Swift version 3.1 (swift-3.1.1-RELEASE
