Normally I don’t post about yet another Photoshop and Sketch friendly iOS UI set. But this is different; it’s made by the UI8 team, which already has a reputation and history around well done icons, wireframes, and general UI work (I own two paid web wireframe sets from them – the quality holds up.) Most importantly, it’s completely free as long as you provide an email address; it runs normally $78 on UI8’s own web site.
