This would not solve the *general* problem Daryle raised. He’s looking for a way to test the logic of some buffer-boundary-crossing code, which makes sense only if he has multiple buffers, which means he must be using “enumerateBytes”, which not supported by Collection<UInt8>. If he doesn’t use enumerateBytes, then he doesn’t need anything but Data anyway. However, considering what appears to be the *actual* problem (finding the first CR or CR-LF or CR-CR-LF separator in a byte sequence), he could use Data without using enumerateBytes, and still not risk copying the data to a contiguous buffer. This solution would use Data’s “index(of:)” to find the first CR, then a combination of advancing the index and subscripting to test for LF in the following 1 or 2 positions. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
