I've read around for different solutions but nothing seems to work. This code creates a nil exception:
[NSFontAttributeName: UIFont(name: "Raleway-SemiBold", size: 16)!]
I have the fonts installed properly and they show up correctly in the app (target is set).
I tried to add the application provided fonts in the plist
but nothing happened. I can't edit the items in the array: (they are item0 : string : Raleway-SemiBold.tff)
.
So basically I'm stuck... Sometimes Swift and Apple environments are great for a programmer, other times (most of the time), they are sooo faulty and need so many workarounds to reach the expected results.
Many thanks in advance for any help.
To use a custom font, add the font file that contains your licensed font to your app, and then apply the font to a text view or set it as a default font within a container view. SwiftUI's adaptive text display scales the font automtically using Dynamic Type.
An NSAttributedString object manages character strings and associated sets of attributes (for example, font and kerning) that apply to individual characters or ranges of characters in the string. An association of characters and their attributes is called an attributed string.
You Just have to write the correct string name of your font.
Don't write the name that is font file name. (like bodoni-mt-bold.ttf its the file name i have downloaded from any site).
To find out the exact font name follow the image below.
Go to your label select it and go to custom font and then see the name of your custom font in its family. if your custom font name is there then copy that name and past it as a string where u wanna use it. (Note you can't copy font name text you have to write else where then past it)
You're getting an exception because UIFont(name: "Raleway-SemiBold", size: 16)
returns nil
and you're force-unwrapping it with !
.
Instead, use conditional unwrapping:
if let font = UIFont(name: "Raleway-SemiBold", size: 16) {
let attributes = [NSFontAttributeName: font]
// do something with attributes
} else {
// The font "Raleway-SemiBold" is not found
}
You can use UIFont
's familyNames()
and fontNamesForFamilyName(_:)
methods to get the exact string required.
Swift 4
if let font = UIFont(name: "Raleway-SemiBold", size: 16) {
let attributes = [NSAttributedStringKey.font: font]
// do something with attributes
} else {
// The font "Raleway-SemiBold" is not found
}
For Swift 3, here's an update that worked for me:
First you'll set up the font and then create a textAttribute
with the NSFontAttributeName
:
let font = UIFont(name: "Raleway-SemiBold", size: 16)
textAttribute = [NSFontAttributeName: font as Any, NSForegroundColorAttributeName: UIColor.black]
You can then apply textAttribute
to your label, textfield etc.
