Update to Swift 1.2 with workaround for compiler crash

[beltex]

Hi @kareman! I saw your comment about the compiler crash, so I took a look! Seems like its the workdirectory property with it’s getter thats causing the compiler crash. I’ve submitted it to the swift-compiler-crashes project.

As a workaround, made workdirectory a struct with static get() and set() functions. All tests pass except for a few in Stream_Tests.swift, which as far as I can tell is unrelated to the workdirectory change, but certainly new as a result of Xcode 6.3.

These hang at runtime:

• testCustomStream
• testStreamFromArray

While these crash at runtime:

• testSequenceOfStreamsToStream
• testChainWithSequenceOfStreamsPrintedToStream
• testChainWithSequenceOfStringsPrintedToStream

@beltex :+1: excellent work, I was dreading having to decipher another segmentation fault 11 compiler crash.

Instead of moving it to a struct I turned workdirectoryinto an extension on NSFilemanager, so you can go File.workdirectory = ... etc. I really want to move tempdirectory there too for consistency but you can't store anything in extensions. I will probably move workdirectory back to the global level when this compiler bug has been fixed.

I disabled the 3 unit tests that crash at runtime until I can find a fix for them. The 2 tests you mention hang at runtime, plus a couple more, only hang when run individually. When running all unit tests at once they work fine. Weird.

np! :)

Nice, yeah thats better than the struct, maintains the original usage style.

Cool, didn't know you could disable them like that! And strange indeed with the hangs.

Good news, looks like this compiler bug has been fixed in Xcode 6.3 Beta 2 :)

No luck on the tests though.

Indeed, thanks for letting me know. I reverted the changes to workdirectory here: f76c81edc2198fdcb048bc0306b8a795697011c6
