In swift: // a is a UInt64 let a = Int.random(in: 0..<Int.max) // causes a fatal runtime error if out of range, halts execution let b = UInt32(a) // returns a UInt32?, which will be nil if out of range let c = UInt32(exactly: a) // another approach for exact conversion: guard let d = UInt32(exactly: a) else { // conversion failed // handle error and return return } // 'd' is a UInt32 without any bits lost // always succeeds, will return a UInt32, either clamped or truncated. Truncation just cuts off the high bits. let e = UInt32(clamping: a) let f = UInt32(truncatingIfNeeded: a)
