Error using app Unrecognized font family 'Rubik-Regular'. App works fine after dismissing. Just posting this since I could not resolve it through other issues I found online.
Also, unable to load RestaurantsApp until I upgraded RN 0.38.
Will post a PR if I am able to resolve.
Hey @r-bansal! Thank you for submitting this issue.
This looks like something gone wrong with react-native link. Could you try to link it again and post here the answer? If that was the issue, we will release the fix this week.
Same error appears for me, version below.
jays-Air:washery jack$ react-native -v
react-native-cli: 1.3.0
react-native: 0.36.1
jays-Air:washery jack$ react-native link

I had the same issue even after trying to link it again, but restarting the app using react-native run-ios resolved the issue for me
Hi, Same issue here. And neither react-native link or react-native run-ios solve the issue.
EDIT: I think it comes from the fact that I use RN 0.40.
@benjaminb10 Why do you think it's because you're using RN 0.40?
'Cause when I've tested with a new RN 0.39 app it was working.
I have the same issue, this is what I'm using:
react-native-cli: 2.0.1
react-native: 0.40.0
It seems it's broken for 0.40.0
Experiencing the same issue.
Same issue, none of linking or rerunning the app worked. Any updates on this issue?
Same here, hope for quick update
the same issue
@ojardila @paduvi I found a fix. You have to add the fonts file in Xcode and re run it. Follow this example https://github.com/oblador/react-native-vector-icons#installation . see the option manually and whichever font u include in ur app also include it in Xcode.
Happy coding :)
Same problem here. Files are in the project and referenced in info.plist, but I keep getting this message.
Same issue.
I am getting this too. It brings development to a stand still. Help!
Faced the issue today :(
Yeah same for me:-(. Please reopen this one!
I'm just trying out Shoutem UI and got the same error…
Same issues...
react-native-cli: 2.0.1
react-native: 0.40.0
Why it is closed? Same issue react-native 0.40.0
A resolution is that drag the folder 'node_modules/@shoutem/ui/fonts' to your project in Xcode. And then edit Info.plist, add a property called Fonts provided by application and add the fonts to the list. Like this:

My project already has this fonts listed. But the error remains. :/
I had this same issue with a brand new project, after installing @shoutem/ui. At first I had to deal with Issue #134 (update and re-link imports), then the build succeeded. Unfortunately, as soon as I added a NavigationBar, I was presented with this missing font error as well. The Fonts do in fact exist in the Xcode project, as well as in the node_modules.
RN: 0.40
XCode: 8.2.1
ShoutEm/UI: 0.10.9
react-native-vector-icons: 2.0.3
Even though I had relinked the icon package when working with the first issue, re-linking react-native-vector-icons explicitly, allowed me to resolve this issue.
$ react-native link react-native-vector-icons
I know it is quite simple, and may not work for everyone, but in my case it is what worked.
Broken in 0.41.2 as well. @SoHotSoup can we get this reopened please? It seems like the vast majority are experiencing this bug.
@dazziola I can really promise you we will release a new version next week, and really sorry for this issue.
And thank you guys for being that patient!
Hey I tried react-native link react-native-vector-icons but now I get these errors fro RNVectorIcons Redefinition of RCTLogLevel... and a bunch of other errors. Anyone know how to fix or undo? Unlinking didn't work.
I use "npm i -S react-native-vector-icons" and "npm i -S react-native-linear-gradient" to solve problem ,but I use "NavigationBar",always can't use " styleName="clear"",if I use ,the "NavigationBar" will disappear,@SoHotSoup , How can I fix it?
Hey @willluck, I don't really understand what is the problem, could you attach some screenshot or write exact code snippet here?
Thanks @willluck , this fixed!
yarn add react-native-vector-icons
yarn add react-native-linear-gradient
Or using npm i -S;
Thanks ,but use "NavigationBar" and set " styleName="clear" ,the effect will be displayed correctly?@csbun
It comes out something like this:

Here are my code:
<Screen>
<NavigationBar
styleName="clear inline"
leftComponent={<Icon name="sidebar" />}
centerComponent={<Title>TITLE</Title>}
/>
</Screen>
about
styleName="inline"#57 #104
Yes,if use styleName="clear ,the centerComponent={<Title>TITLE</Title>} will disappear@csbun,@SoHotSoup
This solution also worked for me:
yarn add react-native-vector-icons
yarn add react-native-linear-gradient
This is fixed with latest release v0.12.0. Thank you guys for being this patient!
@comiclee Thanks, I have using same tricks and it works for me.
@SoHotSoup This just happened to me in v0.12.1. Adding react-native-vector-icons and react-native-linear-gradient did solve it for me though.
Hi @annedroiid I am having the same issue, tried with this but still can´t get to load that font. Any suggestions?
Had the same issue and only adding it to Build Phases -> Copy Bundle Resources Fixed it.
