Runtime errors when using with swift

[dcunited001]

However, I'm still getting runtime errors with FontAwesomeKit. The following crashes on the first line. I posted my setup information in #46

let playIcon = FAKFontAwesome.playIconWithSize(15)
print(playIcon.attributedString())
self.btnPlay.titleLabel?.attributedText = playIcon.attributedString()

Is this something that can be easily addressed? I need to get my app running in the simulator again, I'll post the error message soon.

here's the line of code causing the crash:

    icon.mutableAttributedString = [[NSMutableAttributedString alloc] initWithString:code attributes:@{NSFontAttributeName: [self iconFontWithSize:size]}];

here's the crash i'm getting in the simulator:

i think this error has something to do with the lazy-loading issues mentioned in the Known Issues. However, I have my podfile setup to use_frameworks in my project, so I'm not sure I can set the the compile time DISABLE_FONTAWESOME_AUTO_REGISTRATION directive. I might be able to define that in my bridging header, but i still don't know how to manually register the icon fonts.

I've tried adding the following to my AppDelegate application didFinishLoading, but i still get the same crash when I try to use the font in my Controller.

FAKFontAwesome.iconFontWithSize(1)

If you look at the code in +[FAKIcon iconWithCode:size:], the likely culprit is that +iconFontWithSize: is returning a nil font. Since you also mention you're using frameworks, my guess is that you're hitting a bug that was fixed in January of this year, but for some reason there has not been a release since then. If you install via Cocoapods and don't reference a specific commit, you will still crash. The problem is that the buggy code is trying to load the font file via the main bundle, but when using frameworks, those fonts are in the framework's bundle.

Try replacing your pod reference with this:

pod 'FontAwesomeKit/FontAwesome', :git => 'https://github.com/PrideChung/FontAwesomeKit', :commit => 'ac17a6c'

@PrideChung: have you considered releasing a new version so the bundle loading fix is more easily available?

[PrideChung]

@sjmadsen Yes, I do planning a new version to fix this problem but still can't make it work on watchOS.

I just ran into this issue too. Thank you for the fix. Hope to see a new release soon.

I tried using 2.2.0, and it seems to have this issue still when using it with frameworks. I took the known issues into account. Has this been migrated to 2.2.0?
