I want to see the white dots only in indentation, but it is showing as blank spaces
I've used the toggle render whitespace option but it wasn't what I was expecting. How can I set remove these dots?

You can't, because Xcode doesn't render code that way. However, those vertical lines are often used to indicate which lines will be collapsed or folded, and Xcode does support code folding:
The vertical gray bars next just to the right of the line numbers are Xcode's way of showing how code is nested. If you place the cursor over one of those bars, Xcode highlights the beginning and ending braces. Clicking on a bar will fold the corresponding block down to a single line with ... between the braces. This is similar to what the vertical indentation lines do in some other editors.
Having global-linum-mode on creates extra space on the left hand.
How do I get rid of this extra space and just show the line numbers?
Picture:
The extra space that appears on the left side of the buffer when global-linum-mode is enabled is caused by the default linum-format setting, which adds a certain amount of padding to the line numbers to make sure they align properly.
To get rid of the extra space and just show the line numbers without any padding, you can customize the linum-format variable. This variable determines the format of the line numbers in global-linum-mode, and you can set it to a format string that doesn't include any padding.

'(linum-format "%d"))
In NetLogo 6.1.1, in the link editor, there are four line styles: solid, dotted, dashed, and a more complex dashed pattern.
However, when the visual representation of a link is thick, the spaces between dashes become invisible. It seems that the thickening surrounds each point in every direction, so that in thick lines, the color of the line overlaps the space between dashes.
Is there any way to edit dashes to create more space (or to produce better behavior for thick lines)?
Are these findable? I've turned them myself because I could only find left and right. I want it to be the text of my buttons.
The closest match is probably:
PRESENTATION FORM FOR VERTICAL LEFT ANGLE BRACKET (U+FE3F): ︿
PRESENTATION FORM FOR VERTICAL RIGHT ANGLE BRACKET (U+FE40): ﹀
Technically, these are punctuation characters from the CJK compatibility block used for vertical writing systems. What you're really looking for is an arrow-like symbol.
Try using a special font, like FontAwesome. Check out chevron-up and chevron-down.
I have to agree with some other responder, though, that SVG or even a sprite image would be better. You can set the text to be the unicode characters and style the element to show the image, so that selecting it and copying would give you the text.
I would like to change (or hide entirely) the "bent arrow" character that appears in the Emacs fringe (both on the left and right hand side). I'm using Emacs 24 on a Mac, installed via homebrew. I find it to be visually distracting. A smaller character, like a center dot, might work well.
For context, this is an official description of the small bent arrows (from http://www.gnu.org/software/emacs/manual/html_node/emacs/Continuation-Lines.html):
Sometimes, a line of text in the buffer—a logical line—is too long to fit in the window, and Emacs displays it as two or more screen lines. This is called line wrapping or continuation, and the long logical line is called a continued line. On a graphical display, Emacs indicates line wrapping with small bent arrows in the left and right window fringes. On a text terminal, Emacs indicates line wrapping by displaying a ‘\’ character at the right margin.
The Emacs LineWrap Wiki page does not address my question.
The best information I've found so far is contained in this StackOverflow answer:
When word-wrap is set to nil in a text terminal (-nw) Emacs, the backslash character appears on the right margin.
When word-wrap is set to t in a text terminal Emacs, the backslash character is not shown. Setting visual-line-mode also sets word-wrap to true.
This does not apply when Emacs is running as a GUI window: the small bent arrow appears on the right margin regardless of the value of word-wrap.
Is hiding or changing the bent arrows possible? If not, an answer that says, more or less, "I've looked at X and concluded that it is impossible" is ok too.
Update: Although it is not a terrible work-around, changing the fringes is not what I'm looking for: I want to customize the "bent arrow" character or bitmap.
First, some quick context. From Emacs Fringe Bitmaps: "Fringe indicators are tiny icons displayed in the window fringe to indicate truncated or continued lines, buffer boundaries, etc."
You cannot replace the curly arrow with arbitrary text. According to lunaryorn's answer to "Is It Possible To Replace Fringe Bitmaps With Text in Emacs?":
No, it is not. Fringe “bitmaps” are really bitmaps, that is vectors of 0/1 bits, overlayed over the fringe. There is no way to directly render arbitrary unicode characters onto the fringe. [...] What you can do, is to render a unicode character into a 0/1 bitmap yourself.
Like it says, you can change the bitmap. Fringe Bitmaps contains a list of fringe bitmaps; left-curly-arrow and right-curly-arrow are the ones relevant for this question.
Here is what I drew up. Adjust to your liking. Put this in your Emacs init file.
(define-fringe-bitmap 'right-curly-arrow
[#b00000000
#b00000000
#b00000000
#b00000000
#b01110000
#b00010000
#b00010000
#b00000000])
(define-fringe-bitmap 'left-curly-arrow
[#b00000000
#b00001000
#b00001000
#b00001110
#b00000000
#b00000000
#b00000000
#b00000000])
More documentation is available at Customizing Bitmaps, including set-fringe-bitmap-face which "sets the face for the fringe. If face is nil, it selects the fringe face. The bitmap's face controls the color to draw it in".
