infinite with xcode 9 GM

[bricecesarin]

Hello,

I tried my project with the new xcode 9 GM today, the BartyCrouch script never stops.
So I tried launching command :
bartycrouch interfaces -p [My Project Path] -v
The script is working for some files and then stops for one.
I tried launching with the source file and found that the problem comes from the file : Commander.swift , the line let outdata = outpipe.fileHandleForReading.readDataToEndOfFile() never stops.

I reproduced the same issue with a second project.

My XCode version is : 9.0 (9A235).

Hello bricecesarin ! I've exactly the same issue with my project with the last Xcode version.

I am also seeing this.

The bartycrouch interfaces command hangs indefinitely, but if I run /usr/bin/ibtool --export-strings-file directly, the strings are still exported, though with a bunch of warnings: 2017-09-13 13:37:43.724 ibtoold[3253:4694192] WARNING: Unhandled destination metrics: (null) (which are being read correctly in the errPipe)

xcode-select points to the GM right now (though I have the old Xcode still installed)
ibtool --version:

<key>bundle-version</key>
<string>13196</string>
<key>short-bundle-version</key>
<string>9.0</string>

The nib it hangs on does have autolayout errors and if I delete the views causing the errors, bartycrouch runs fine. (Right now, I can't figure out a way to resolve the errors, IB is being weird).

I'm trying to create a simple nib from scratch that exhibits the same problem. I'll share here if I'm successful...

If I had to make a guess, it seems like this new version of ibtool isn't giving an end-of-file indicator to standardOutput when there are errors (in this case, warnings).

It looks like commenting out let outdata = outpipe.fileHandleForReading.readDataToEndOfFile() (so just ignoring the standard output) and the rest of the command runs fine, the string files get made.

Not that this is an actual solution or anything, just experimenting.

when I launch ibtool command from command line :
/usr/bin/ibtool --export-strings-file [myTmpStrings] [MyXib]
the warnings :
WARNING: Unhandled destination metrics: (null)
are appearing for all xib (event those which works).
It seems like the output are not different from the working xibs and the no-working xib.
Still, fileHandleForReading.readDataToEndOfFile() does not end for the no-working xib.

[bricecesarin]

The only output difference is :
/usr/bin/ibtool --export-strings-file [myTmpStrings] [MyWorkingXib] : less than 250 warnings
and
/usr/bin/ibtool --export-strings-file [myTmpStrings] [MyNoWorkingXib] : more than 250 warnings
Same thing with my 2 projects

I got a fix.
Simply reading stderr before stdout solves it.
