@JonB As usual, you're the 🤴
@JonB, thanks. Intuitively this seems like it should be faster and more efficient than going via the PNG conversion.
But when I went to test the performance I ran into a couple of issues with the asset approach:
- Resulting image size is dependent on the size of the original ui.Image created.
- Both the original and ”asset-applied” images are retained in the ui.Image somehow, and for example ButtonItems do not really handle that well.
See below couple of example images. First one uses a too-large initializing picture (Lenna), the second too small one (triangle arrow icon), which you can see presented in the title area.
@mikael your module now crashes with

@cvp, yes, just noticed. iOS 14 must’ve changed it. Will take a look.
@cvp, here’s the relevant code if you want to do a manual quick fix. Will push an update to PyPI soon.
... if point_size is not None: conf = conf.configurationByApplyingConfiguration_( UIImageSymbolConfiguration.configurationWithPointSize_(point_size)) if weight is not None: conf = conf.configurationByApplyingConfiguration_( UIImageSymbolConfiguration.configurationWithWeight_(weight)) if scale is not None: conf = conf.configurationByApplyingConfiguration_( UIImageSymbolConfiguration.configurationWithScale_(scale)) objc_image = objc_image.imageByApplyingSymbolConfiguration_(conf) ...
@cvp, for the new symbols, I found a downloadable list of changes, but no list of new icons or an updated master list.

If someone interested in a list of string, here we go
import plistlib import io vFilePath = '/System/Library/CoreServices/CoreGlyphs.bundle/symbol_order.plist' with open(vFilePath, 'rb') as vFile: vFileObject = io.BytesIO(vFile.read()) vJsonSFSymbols = plistlib.load(vFileObject) for vIndex, vJsonSFSymbol in enumerate(vJsonSFSymbols): print(str(vIndex).zfill(4), vJsonSFSymbol)
@7upser, excellent! I ran a quick comparison, and the plist list has all the symbols that the ”manual” list had, plus 162 additional symbols all ending in one of: ar, he, hi, ja, ko, zh or rtl, which I take to be additional language-based versions.
With this, when I have a moment, I can probably change the symbol browser to show whatever you have available in your iOS version, rather than relying on a manually updated list. What seems to be missing, though, is the marker for the symbols that Apple says must not be used outside their Apple context (like ”airpods”).

I'm missing the Categories for SF Symbols.
I think there are only Categories in the Mac App.
I found two older version and a Screenshot for the new Gaming Cat.
I add some cats for newer Symbols, but didn't finished.
This is what i have (with Pythonista Symbols and Emojis)
Names of restricted Symbols are here:
(also a plist file)
