SFSymbol | SFSymbols 4 through 1.1 at your fingertips | iOS library

I need to have a circular UIButton that draws a custom color in the middle, along with an outer ring that is drawn as the default tint color (similar to a UIColorWell).

I've tried a few different approaches:

1. Using a multicolor SFSymbol: This would be an elegant solution, but as far as I can tell there's no way to apply the tint color to just a part of the image while setting the center to be a custom color. Either the entire image is tinted, or the image is drawn as the default colors set in the symbol file. Also, I need to support iOS 14, while the new hierarchical options that may allow me to accomplish this were added to iOS 15.
2. Setting various layer properties (ie, cornerRadius, borderColor, etc): This works and may be a decent fallback solution, but I'm unable to get the look that I'm going for (namely, having a transparent ring between the outer border and inner colored circle).

If there's a way to use either of the above options, please educate me! Either one seems like a better solution than:

1. Overloading the draw function: This is the option I'm going with at the moment, as it allows me to have complete creative control over the look of the button. The rest of this post will be regarding this method.

So far I was able to get the button to be drawn exactly as I wanted. However, I am unable to figure out how to draw the button appropriately with regards to various state changes.

For example, if a popover is displayed, all of the normal buttons are automatically redrawn as disabled. My custom button, however, isn't redrawn so I am unable to respond to the state change.

Same thing with tapping on the button - normal buttons are briefly shown in an emphasized color but my custom button doesn't respond.

Does someone have an example as to how to support overriding UIButton drawing with various states?

I want to align the heights of two HStack members. The expected outcome would be that the image has the same size as the text. The current outcome is that the image has more height than the text. This is my current setup:

This seems like really easy to fix, But I can't get my head around it.

How can i show SFSymbols' shift.fill if the list of upvoters contain Foo and if not, show shift

I was looking here at this to try to solve my problem, and many said that this was fixed in the latest XCode version, but it is not working for me and I am on the latest public XCode version that supports iOS 14.5. I have a few arrays that each contain info such as a name, number, and description. I want each of these to appear as buttons and then when tapped on to show a sheet with a unique view to that button.

Here is a shortened example of one of my arrays:

So my problem is that I am trying to align text from different HStacks. Different sized SFSymbols are causing this problem.

I know that AlignmentGuide can solve my problem but I'm not sure how to implement. If anyone can lend any insight I would be greatly appreciative!

I have watched the WWDC talk on this.

And this is the main screen that relates to this problem,

Yet I need a little clarification of to put it together.

Here is relevant code

I have the following 3 components within a Horizontal stack view.

1. Yellow UILabel
2. Red UIImageView
3. Green UIImageView

The distribution for the Horizontal stack view is Fill.

The content mode for UIImageView is Aspect fit. They are using SFSymbol named "pin.fill".

The number of line for UILabel is 0, so that it supports multilines.

All the 3 components are having same Content Hugging Priority (250) and Content Compression Resistance Priority (750)

My questions are

1. Why the red UIImage take up most space, even though all 3 of them are having same Content Hugging Priority (250) and Content Compression Resistance Priority (750)?
2. My intention is letting yellow UILabel fill up most space. However, I can only achieve so, if I increase the Horizontal Content Compression Resistance (For UILabel only) up to 999 or 1000. I thought, as long as any value is higher than 750 will be good enough? Does 999 or 1000 value in Horizontal Content Compression Resistance carry any special meaning?

Please do take note that, even when Horizontal Content Compression Resistance for UILabel is 999 or 1000, both red & green UIImageView's width will be compressed. But, they are compressed with different strength, which end up 2 UIImageView are having slightly different width. Why?

I'm working on some code to teach myself SwiftUI, and my current project is a dice roller app.

In my view, I present some images using SFSymbols to represent the value of each die after the roll. I use two animations (.rotation3Deffect and .rotationEffect) on each image to give a visual roll of the dice.

I have found that the animations will only run if the individual die value (or in case of the code, if the Image(systemName: "\(diceValue).square.fill")) changes from one roll to the next. In other words, if I roll three dice, and they land on 1-4-6, then I roll again and they land on 1-4-7, the 1 and 4 images will perform the animation, but the image changing from 6 to 7 does not animate - it just updates to the new image. Any idea why the animation only runs on the images that did not change from the previous dice roll?

I have 2 HStack's using geometry reader to split them evenly into 2 sections that are embedded into a VStack, I am trying to create a layout similar to the first below image (landscape mode on iPad).

However, I am struggling to get the HStack's to line up like a grid meeting in the middle. I also have a NavigationView sidebar and which can be presented alongside the HStacks so ideally the 2 images would change widths but keep their height without squashing or stretching the images. I have tried to do this using clipped().

The second image below is what I am getting when I run my code. I have replaced the images in this example to SFSymbol to make it easier to debug.

This is the NavigationView sidebar that is being called in my ContentView:

I am trying to add an icon ( SFSymbol) called "exclamationmark.triangle" if the field is empty to identify that it's a required text field. Below is the method I used. It works, but not properly. When the user clicks on a text field and starts typing after the first character keyboard goes away, so the user has to retap to continue typing.
