Fixed the link earlier tonight. Though Stacy already noticed Beta 3 introduced some new issues that weren’t there in Beta 1. I explained to Stacy, unless you are planning to modify the code, working with the Betas and the kit is going to be a world of unnecessary pain. Every update to the Beta could introduce a new issue, which means you’ll need to keep replacing the code. Plus at the very earliest you’ll have to wait until iOS10 to submit your app, whereas if you go with the stable current version of Xcode, you can submit your app as soon as its ready.
So if you’re just working with the property list and not tinkering with adding your own code, I really wouldn’t go into Beta world. =)
