I would like to draw a text in my custom view at point X,Y with center allignment. In case the text would be "SUGUS", I expect to have the Character G at Point X,Y.
I tried several things with NSString.drawinRect(), where I have to provide the width of the text, which has to be measured first depending on the Fonttype. It worked, but for me thats not a straightforward solution.
I purposely did not add code here, because a first try with code was misleading and I hope someone can help me with a clean simple solution ?

please see the image below for two examples of what is to be achived
the alignment should be on the Center Y of the first lines of each UILabels and should work regardless of font size or font. currently we have implemented this with different constraints to the top of the super view for different font and font size combinations.
the constraint to align the center of the two UILabels does not work since the text of the second UILabel is not fixed and can have several lines.
also the text is dynamic, so it is not known where the text will wrap to create the first line, thus it cannot be shown in an one line UILabel with the rest of the text in another one below.
currently this is implemented using UIKit, but if there is an easy solution in SwiftUI we can put these two labels in a SwiftUI component. so a SwiftUI solution would also be welcomed.
Your comments said "it should be on the glyphs" ... but, without additional information, my guess is that "real world" usage would not really need that level of precision.
For example:
While the glyphs are not perfectly center-Y aligned, it seems unlikely you'd run into a case where the first line of the "rightLabel" is " ' " ' " or . , . , ..
This layout can be easily done with only a few constraints - no need to do any calculations:
The "Positioning" label would, of course, be set .hidden = true so it would never be seen.
If you really, really want glyph-precision, you'll need to calculate
the Glyph bounding box for the left-label
the Glyph bounding box for first line of the right-label
calculate the "character box" offsets to align the Glyph Y-centers
and then position the two labels accordingly, or use Core Text to draw the text (instead of using UILabel).
Probably more work than necessary -- unless your actual use-case demands it.
That's an interesting problem! You can try using the centerYAnchor for the label on the left, and the firstBaselineAnchor for the label on the right... that will align the center Y with the text baseline, which isn't quite what you want.
To find the correct offset to apply, you can use the information from UIFont about the size of the characters. I'd probably start with capHeight * 0.5 and see if that looks or feels right. Something like:
leftLabel.centerYAnchor.constraint(equalTo: rightLabel.firstBaseLineAnchor, constant: rightFont.capHeight * 0.5)
This is a more difficult problem in SwiftUI, I think, because resolved font metrics aren't directly available to you.
Has anyone managed to pin down a method for creating cards in Sketch which will play well with adaptive height text overrides? For example, a simple card with a thumbnail, title and excerpt might have a title which is 1, 2 or 3 lines and an excerpt which is anything between 6 and 12+ lines. I'd like to know how to position the excerpt relative to the new height of the title but it seems not to interpret the new three-line height, only it's original height in the symbol. See attached for illustration.
Methods that I've tried include pinning the excerpt to the bottom but that doesn't play well with the variable length of the excerpt and grouping the title and the thumbnail. The only working method that I have is creating three instances of the symbol called post-title-one-line, post-title-two-line, post-title-three-line – which seems clunky.
Looking for any ideas or direction to a solution.
My recommendation is to use the Auto-Layout by Anima plugin. Follow the documentation and examples provided to learn how to use it. Here's an example solution:

I've been trying to create my app and something is bugging me very much,
I have images of what I am trying to achieve:
1)
2 )
number 1 shows what I am trying to do, the letters are "squeezed" together making the text appear tighter with a short width even though the letter sizing is big.
number 2 shows my attempt to achieve this, I tried multiple different ways to get that same look but failed for hours, does anyone have any suggestions or know how to make the text look like that in the first picture?
I appreciate any help, thank you!
The only way how to do it AFAIK is to use transform on UILabel, like this:
let widthTransform = 0.8 // Shrink label to 80% of its width
label.layer.transform = CATransform3DMakeScale(widthTransform, 1.0, 1.0);
Hope it helps!
Note* that transform work for about 30% of decrease (even less imo), then it just starts to look very bad. You can also change text spacing, but if you calculate it dynamically, you could end up with negative one and that looks terrible. The easiest way really is then just change of the design :)
Options:
You can decrease character spacing like in this answer
and increase font size.
Having fun with transformation on layer is really awful idea, as later you won't be able to get the height of text etc -> just everything will be working wrong.
You can also just use different font.
I would like to implement karaoke-like progress highlight for iOS.
I know I could use NSAttributedString and highlight the text character by character. However, I would like the highlight to progress pixel by pixel, not character by character.
Any ideas?
P.S. No need for sample code, just point me to the right direction.
Here is an example:
I can't think of any automatic way to do that. There would be several problems to solve. It would be pretty hard, I think.
The hardest would probably be figuring out the pixel position of each word so you can pace the coloring to match the timing within the music. With text and attributed layout, you could probably get the text engine to give you the boundaries of each word and then apply the color attribute to each word as it's spoken/sung. You'd have to have data about the time offset for the beginning and end of each word's being sung.
You might have to use Core Text to get layout information about the bounding rectangles of each word.
Once you get that you could build a path (UIBezierPath or CGPath; they're pretty interchangeable) that follows the flow of the text, and then install that path in to a shape layer. You could then make the text transparent, make the shape layer a colored background that shows through, and animate the shape layer's strokeStart and/or strokeEnd properties to make it fill the text. You might need to do it word by word with a short animation that interpolates between one word and the next to get the timing right.
You probably want to have a look at Core Text, which is the lower level framework used for laying out text, using this you can obtain necessary paths that you need to render said effect (I suggest starting from answers similar to this)
There are plenty of answers for alternative, perhaps simpler answers, for example character by character or word-by-word, which may be easier to implement.
I trying to create a fixed border to the site that dynamically change size with the browser window from this sprite (it isn't perfect I know.): http://fc07.deviantart.net/fs70/f/2011/269/7/0/bordersprite_by_nakos-d4ayzne.png

My problem as you can see is the vertical wall part. As the #falJ and #falB are height:100% they include the bottom wall's end too with the space between the two wall sprites. Is there a way to force backround-position to only use vertical wall part without bottom wall's end?
Thanks in advance.

It's not the prettiest thing in the world, but it achieves what you want. Check out the source code & direct link for the background images to see what you'll need to do. It's currently set at 299px wide; I imagine you'll be using something wider.
I'd also suggest adding some padding around your content (either with a p tag, span, another div, etc.) - the way it is currently set up isn't what I'd recommend for readability.
EDIT
The only way I can imagine achieving a fluid width + height box with the borders that you have in the way that you want is to use a second image for the west and east containing divs. This should work with your current method.
