Sidenote but interesting to see the different file sizes for the same thing. Can't remember last time I used Photoshop for web design, but I would suppose file sizes increase time to open/edit/work in the files depending on file size(?)
For Photoshop iOS 11 (665.0 MB)
For Sketch iOS 11 (38.5 MB)
For Adobe XD iOS 11 (7.7 MB)
Seems to use a new font, SFPro.
Holy font sizes batman!
After they made such a big deal about safe area and margins, I find it frustrating that there are no measurement details documented anywhere, and no examples in their Sketch files.
Even if the safe area is a variable size (which it likely is, after looking at XCode), they only have a handful of trait collections. Why leave out such important details?
