Yes, I am indeed using the XCode App Template (probably should have said this in the first placE). This thread discussing integrating Ads, but not in-app purchases. It also indicates objc_util is the way to go. I'll do a bit of research
Just to give this a little bump...the issue seems to happen when I use anything other than the basic fonts e.g. if I use Courier or Arial they appear fine in both the Pythonista an the Xcode App, however as soon as I user anything like 'Arial Bold' or 'Arial Rounded' it will show up fine in the Pythonista App, but appears tiny in the Xcode app. seems like somehow the Xcode template doesn't support the font variants. Any ideas?
