Xcode 8 and Swift 3.0

Any chance of getting the syntax for Swift 3? Or advice on how to proceed with Xcode 8 and Swift 2? I can’t build after updating Xcode. I have NOT converted code to Swift 3?

I ran into this problem and to solve it you need to:
– select your project in the left hand pane of Xcode 8,
– then in the right hand pane, click on Build Settings at the top
– then look for ‘Swift Compiler Version’ in the right hand pane
– Set ‘Use Legacy Swift Language Version’ to Yes,
…and you should be able to build again.

Worked for me…
