What is the equivalent of NSLineBreakMode in iOS 7 attributed strings drawing methods?
You need to create a paragraph style.
NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
[style setLineBreakMode:NSLineBreakByWordWrapping];
NSDictionary *attributes = @{NSFontAttributeName: font, NSParagraphStyleAttributeName: style};
[self drawInRect:rect withAttributes:attributes];

In Swift 5:
let style = NSMutableParagraphStyle()
style.lineBreakMode = .byWordWrapping
let attributes: [NSAttributedString.Key: Any] = [
.font: font,
.paragraphStyle: style
]
