A:

The initializer for views is not init, it's initWithFrame:. Furthermore, if your view is in a nib, you must also override initWithCoder:. Don't forget to make sure your view is actually a PTNfoEditField, not a regular NSTextView.
Also, you should use [NSFont userFixedPitchFontOfSize:0.0] to set the font. You should hard-code neither the font name (the user may prefer a better monospaced font) nor the font size (the user may find 10-pt hard to read or have their anti-aliasing threshold set above it).

 Q:

Refactoring a String Calculator

I've refactored the string calculator kata as much as I could and tried to maintain single responsibility. Is there anything I could factor differently? The specs can be reviewed here.
module StringCalculator
  def self.add(string)
    string.end_with?("\n")? fail('ends in newline') : solve(string)
  end

  def self.solve(string)
    verify(string)
    custom = delimiter(string)
    numerics = string.gsub(/\n/, custom).split(custom).map(&:to_i)
    numerics.reject { |n| n > 1000 }.reduce(0, :+)
  end

  def self.delimiter(string)
    string[0, 2] == '//'? string[2, 1] : ','
  end

  def self.verify(string)
    find = string.scan(/-\d+/)
    fail("negatives not allowed: #{find.join(', ')}") if find.any?
  end

  private_class_method :verify, :delimiter, :solve
end

More importantly, I've thought of a case that involves the delimiter of a string that begins with // to be a number (which is considered invalid). I've made a quick way of solving that issue like so. Any suggestions on that?

 The initializer for view is not init, it's initWithFrame: . Furthermore, if your opinion is in a nib, you must also overrule initWithCoder: . Don't forget to make sure your view is actually a PTNfoEditField, not a even NSTextView.
