app transport security problems on iOS 9

app transport security prevents PFFile.getData() from working on iOS 9

Hi there, I'm using the Parse SDK on iOS 9, and I'm running into issues while downloading PFFiles. This started sometime yesterday, without any code changes. Here is the error log output:

[Error]: The resource could not be loaded because the App Transport Security policy requires the use of a secure connection. (Code: 100, Version: 1.8.2)
2015-12-26 10:25:57.652 ephemera[1238:298230] [Error]: Network connection failed. Making attempt 1 after sleeping for 1.011460 seconds.

It comes in repeatedly, as Parse continues to make more attempts to download the file. Here is a code snippet:

//posts is an array of PFObjects
posts.forEach {
  if let data = $0.getData(), type = $0.postType {
    //omitted
  }
}

Hey @prehistoricindustries, thanks for the report.
Is there any chance you can try more up-to-date version of our SDK?
We officially support iOS 9, including App Transport Security starting from 1.8.3.
Taking into account that you are running 1.8.2 - I believe purely updating to the latest version is going to resolve this.

Sure, I'll give that a try. However, this did pique my interest a bit. I've been using 1.8.2 for a little while now, and I only started getting problems yesterday. Was this a change in the Parse backend? I'm only asking because I was very impressed with Parse's support for iOS 9 and App Transport Security since day 1. I had never seen this error before.

It is strange, indeed, since you should have been hitting that long before.
Here is a pull request that implements https for files - #197
Please note that it's marked with 1.8.3 milestone, meaning that it shouldn't have worked on 1.8.2.

Let me know if it works for you now, or please reopen this issue if it doesn't.

Updated to the new SDK, everything works perfectly. Thank you.
