want more helpers?

[gurgeous]

Thanks for creating such a great library! SwifterSwift is amazing and helped me get rid of many of our custom extensions. Want a few more? Here are additional helpers that I can add if you want:

• CGFloat.random
• CGRect x, y, width, height, center, centerX, centerY, left, top, right, bottom
• CGSize init(square: CGFloat)
• String escapeRegex
• UIColor image(ofSize: CGSize)
• UIImage averageColor

UIView

• loadFromNib(withClass name: T.Type)
• frame - origin, width, height, size, top, left, bottom, right
• bounds - boundsWidth, boundsHeight, boundsSize
• constraints - allConstraints, findConstraint(attribute: NSLayoutConstraint.Attribute), widthConstraint, heightConstraint, leadingConstraint, trailingConstraint, topConstraint, bottomConstraint ^ these are for finding existing constraints and are typically used to modify a constant

Let me know if any of these are of interest and I'll put together a PR.

(I also have a fair number of NSRegularExpression, NSString and NSMutableAttributedString extensions but I think those are of less interest. Let me know if you'd like to see those too.)

• CGFloat.random - Part of the standard library
• CGRect x, y, width, height, center, centerX, centerY, left, top, right, bottom - already have min/mid/max(X/Y) etc
• CGSize init(square: CGFloat) - Not a huge saving, IMO
• String escapeRegex - 👍
• UIColor image(ofSize: CGSize) - what's the benefit of this?
• UIImage averageColor - could be interesting

UIView

• loadFromNib(withClass name: T.Type) - Good idea, for now we just have it returning UIView
• frame - origin, width, height, size, top, left, bottom, right - Same as with CGRect, no need
• bounds - boundsWidth, boundsHeight, boundsSize - not much of a benefit here calling boundsWidth instead of bounds.width, for example
• constraints - allConstraints, findConstraint(attribute: NSLayoutConstraint.Attribute), widthConstraint, heightConstraint, leadingConstraint, trailingConstraint, topConstraint, bottomConstraint - 👍 ^ these are for finding existing constraints and are typically used to modify a constant

(I also have a fair number of NSRegularExpression, NSString and NSMutableAttributedString extensions but I think those are of less interest. Let me know if you'd like to see those too.) - If you have anything here that we don't have already please feel free to share

Great! A few more comments:

• UIColor.image(ofSize), creates a UIImage filled with a particular color. Handy for programmatic UI and testing purposes.
• UIImage.averageColor, calculates the average color of a UIImage. This is useful for creating background images. In my current project I use this to figure out if the status bar style should be light or dark over a photo.

Here's what I've got for the other classes:

NSRegularExpression

• versions of enumerateMatches, matches, numberOfMatches, firstMatch, rangeOfFirstMatch, stringByReplacingMatches, replaceMatches that operate on the entire string (no range required)

String

• stringByReplacingMatches(regex, withTemplate) and stringByReplacingMatches(pattern, withTemplate), which call into NSRegularExpression
• squished, which compacts all whitespace and trims

NSAttributedString/NSMutableAttributedString/String

• NSAttributedString.withAttribute/withAttributes, same as applying. Probably we should just make applying public and support the singular case as well.
• NSAttributedString.font & link, similar to color
• NSMutableAttributedString.append(string)
• NSMutableAttributedString.addAttribute & addAttributes that operate on the entire string (no range required)
• String.withAttribute/withAttributes, same as above
• String.font/link/color, same as above

The intent here is to make NSAttributedString, NSMutableAttributedString and String all work together to support attributed properties. I don't know how anyone can build attributed text without this stuff. Example usage:

var s = NSMutableAttributedString()
s.append("\(count) ".font(Self.countFont))
s.append(label.font(Self.labelFont))
s.color(.red)

Here is a WIP for the first set of additions: https://github.com/SwifterSwift/SwifterSwift/compare/master...gurgeous:more-extensions?expand=1

Feedback is welcome. Let me know if this looks good and I will submit a PR w/ changelog entries. Thanks @guykogus!

[LucianoPAlmeida]

@gurgeous Just one note, make sure to open one PR per extension, this makes easier o discuss a single topic in a PR and also for review :)

[gurgeous]

OK, I will break this up into a few PRs and add changelog entries

Thank you! We will take a look at it ASAP :)

I'll go ahead and close this. We can explore the additional helpers listed above in separate issues if we want.
