Since withUnsafeMutablePointers() has gone away, I typed out this example of using nested withUnsafeMutablePointer() so I was sure I knew what I was doing:
var int1 = UInt32(1) var bytes1 = [UInt8(1), UInt8(2), UInt8(3)] var int3 = UInt16(41) withUnsafeMutablePointer(to: &int1) { int1Ptr in withUnsafeMutablePointer(to: &bytes1) { bytesPtr1 in withUnsafeMutablePointer(to: &int3) { int3Ptr in let _int3 = int3Ptr.pointee let _bytes3 = bytesPtr1.pointee let _int1 = int1Ptr.pointee Swift.print("\(_int3), \(_bytes3), \(_int1)") } } }
The output, as expected, is “41, [1, 2, 3], 1”.
