Using xcode 8 beta 6. Type override func prepare and I see this .. But I am looking for prepare(for segue: UIStoryboardSegue, sender: AnyObject?) Is this a bug?

(iPhone 5S or iPhone 5S simulator) Apple seems to be stricter with apps which don't support 64bit. So if there is no specific reason, I think it's better to include arm64 in your

I'm updating my app to Swift 3.0 syntax (I know it's still in beta but I want to be prepared as soon as it released). Until the previous Beta of Xcode (Beta 5) I was able to compare two Date objects using the operands < , > and == . But in the latest beta (Beta 6) this isn't working any more.

I just upgraded to Xcode 6 Beta 4 and have a framework that I created for Live Views in Beta 2. Due to another swift bug , I needed to use some Obj-C code. When upgrading though, I get the following error: error: using bridging headers with framework targets is unsupported I have not seen anything in the release notes, or found any other migration path. Has anyone else seen this and arrived at a solution? I realize that Beta 3 eliminated the need for frameworks for live views, but it makes sense in my case if I can get it to work. I can remove it though as a fallback, but would prefer to use a
