<span class="gmail-">To be more accurate, it's not `print` that
specifies this behavior, but rather the standard output stream's
implementation of `TextOutputStream.write(_:)`. Swift *explicitly*
leaves this choice up to the TextOutputStream-conforming type. That
is, the behavior is up to the receiver and not the argument of a
call to `TextOutputStream.write(_:)`.</span></div>

<span class="gmail-"><br></span></div>
<div>I feel like I must be misunderstanding what you're trying to
say here, because I *think* what you're trying to say is that
`TextOutputStream.write(_:)` is what decides whether to add the
terminator, which is not only totally wrong (see <a href="https://github.com/apple/swift/blob/adc54c8a4d13fbebfeb68244bac401ef2528d6d0/stdlib/public/core/Print.swift#L260" target="_blank">https://github.com/apple/<wbr>swift/blob/<wbr>adc54c8a4d13fbebfeb68244bac401<wbr>ef2528d6d0/stdlib/public/core/<wbr>Print.swift#L260</a>)
but doesn't even make any sense since there's a terminator
parameter on `print` but none on `write(_:)`.</div>
</div>
</blockquote>
<div><br></div>
<div>Hmm, you're right here with respect to `print()`. It is,
however, explicitly contemplated in the documentation for
`TextOutputStream.write(_:)` that conforming types can also
determine whether or not to append a terminator, and which, inside
their implementation of `write`. The example given in the
documentation is:</div>
<div><br></div>
<div>```</div>
<div>
<div>struct ASCIILogger: TextOutputStream {</div>
<div> mutating func write(_ string: String) {</div>
<div> let ascii =
string.unicodeScalars.lazy.map { scalar in</div>
<div> scalar == "\n"</div>
<div> ? "\n"</div>
<div> :
scalar.escaped(asASCII: true)</div>
<div> }</div>
<div> print(ascii.joined(separator: ""),
terminator: "")</div>
<div> }</div>
<div>}</div>
</div>
