What is the correct way to re-write this code:
randomIV = Data(count: 16)
let result = randomIV.withUnsafeMutableBytes {
SecRandomCopyBytes(kSecRandomDefault, 16, $0)
}
To remove this warning:
'withUnsafeMutableBytes' is deprecated: use withUnsafeMutableBytes(_: (UnsafeMutableRawBufferPointer) throws -> R) rethrows -> R` instead
You can re-write it like this:
let result = randomIV.withUnsafeMutableBytes {(bufPointer: UnsafeMutableRawBufferPointer) in
SecRandomCopyBytes(kSecRandomDefault, bufPointer.count, bufPointer.baseAddress!)
}
Or a little more simply:
let result = randomIV.withUnsafeMutableBytes {
SecRandomCopyBytes(kSecRandomDefault, $0.count, $0.baseAddress!)
}
