Writing a zero length array to an OutputStream will effectively close it. The following example demonstrates the issue.
1 2 3 4 5 6 7 8 9 10 | let os = OutputStream(toFileAtPath: path, append: false)! os.open() print(os.hasSpaceAvailable) let d = Data(count: 0) let written = d.withUnsafeBytes { bytes in return os.write(bytes, maxLength: d.count) } print(os.hasSpaceAvailable) os.close() print(os.hasSpaceAvailable) |
