It worked for me .. Using the following codes.
Add a custom font to WatchKit Extension and WatchKit App target Info.plist

Now you write the code as follows,
NSMutableAttributedString *attString =[[NSMutableAttributedString alloc] initWithString: @"Yano rocks! Always"]; [attString setAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"Open Sans" size:20.0]} range:NSMakeRange(0, attString.string.length)]; [self.loadingLabel setAttributedText:attString];
