Parse-sdk-ios-osx: Swift 3 support

[talkaboutdesign]

Will you be updating SDK for Swift 3 compatibility?

[dtalbert]

From my understanding it shouldn't "need" it, being that the SDK is in Objective-C. I've successfully converted Parse projects to Swift 3 with no issues what-so-ever, with Xcode's built in migration tool. I guess if anything needs to be updated it would be the docs.

@dtalbert is absolutely right!
Since Parse SDK is written in ObjC, the transition to Swift 3 is seamless and should involve only your code.
Please open new issues if you experience any problems.

Hello,

I'm trying to migrate my app to swift 3, but when I'm looking at code modifications, XCode change call to SDK methods, for example,

Parse.initializeWithConfiguration(config);

become

Parse.initialize(with: config);

I think that I have to discard this type of change but I'm not really sure, Do you have a best practice to follow?

After converting to Swift 3 all my cloud code gives this error.

@PeterKaminski09 Try to change to

PFCloud.callFunction(inBackground: "usernameValid", withParameters: ["username": username], block: { (object: Any?, error: Error?) in

// some your code

})

I'm completely stumped. Prior to swift 3 I had login and signup working now I can't figure out the Swift 3 syntax.

Also, just starting out, all the examples are with synchronous API + callback/blocks which is what I'm used to. But those are deprecated per the API docs?

https://github.com/ParsePlatform/docs/issues/378

Any help to get me up on my feet would be greatly appreciated.

@nitrag run it like this

PFCloud.callFunction(inBackground: "autoSave", withParameters: ["title": title], block: { (object: Any?, error: Error?) in

when i try to save(by calling object.save, or object.saveinBackground) i get the error below:
