tempTask.status is 1 instead of 0
tempTask.output is "mktemp: mkdtemp failed on com.DanTheMan827.AppSigner.xxxxxxxxxx: File exists\n"

I had previously tried commenting out the return statement, but that fails because mktemp is not actually creating the folder.

However, the File exists message, was helpful. Apparently at some point, the folder was created but never cleaned up, and so it was actually failing because it already existed. However, after trashing it, I get a new error: Error unpacking data.tar

It gets as far as unpacking the .deb and moving it (I can see it in the path /Users/David/Library/Developer/Xcode/DerivedData/iOS_App_Signer-bwbyfgmmbcldethbtdsxlcdbvibk/Build/Products/Debug/com.DanTheMan827.AppSigner.xxxxxxxxxx/deb/data.tar.lzma), but after that it fails to unpack the tar.
output String "tar: Error opening archive: Failed to open 'com.DanTheMan827.AppSigner.xxxxxxxxxx/deb/data.tar.lzma'\n"

Permissions issue perhaps? It does now seem to be cleaning up after itself.

The fix for me was to simply remove the error check. See my attached screenshot, I removed the grey marked area.
Please note that I have zero experience with iOS and / or OS X development, but this seemed a simple hack to try out and I'm glad it worked for me.
After this it ran fine and installed onto my iPad 4 (iOS 9.1, not jailbroken) and runs perfectly fine.




The reason I'm not using El Capitan is that I have a Hackintosh and am happy the way it works now.
