A "fixed-space" or is a typeface where every single character occupies the exact same amount of horizontal space. This stands in stark contrast to proportional fonts (like standard Arial or Helvetica), where an "i" takes up significantly less room than a "w".

The result? Designers building coding tutorial apps saw blank spaces instead of letters. Journalists formatting data tables watched columns dissolve into chaos. Developers testing apps on iOS simulators lost hours verifying that their UI didn’t fall back to the wrong typeface. Workarounds involved deleting and reinstalling fonts repeatedly, restarting devices, or—most absurdly—installing a dummy proportional font first to “wake up” the font system.
To free up space, you can:
Note: This method does not change the system default font (like the text on your home screen), but it allows these fonts to appear in apps like Pages, Keynote, Numbers, Microsoft Word, and Canva.

Load your .ttf file into the utility app to generate an official Apple configuration profile. Step 3: Authorize the Font Profile Open the native app on your iPhone.
For UIKit apps, you can set the font programmatically. There is a specific call for digits only, UIFont.monospacedDigitSystemFont(ofSize: weight:) , which forces numbers to be fixed width but leaves letters proportional.
