Had this problem running ios-deploy 1.8.6 with iOS 10. Fixed it with this patch:

ios-deploy-1.8.6-ios10.diff.zip

@gusc how did you applied this patch? Could you please explain it to me? I'm having the same error on macOS Sierra

[EeKay]

@gusc it seems this is a file containing the code changes. you can apply them by changing the file yourself. This code change might be applied to this git repo soon (i hope).
TL;DR:

1. Go to your ios-deploy install location, probably:
2. open the file /src/scripts/lldb.py
3. remove the line in that file that equals the line in this zip file with the - prefix
4. add the 4 lines in the file with the + prefix on the same location that you removed the one from step 3.

Long version:
Find your iso-deploy location as following:

1. open your terminal and execute:
   type -P ios-deploy
2. this points to the location where a smart link is created to run iso-deploy on your machine. Go to that location in your finder and right click it and select "Show Original"
3. Your in the release dir where the exec is, go up in the tree to the "lib" dir and then select "ios-deploy" and then "src" and "scripts"
4. open lldb.py in your favourite text editor
5. goto line 35 and replace it with:

if len(args) > 1:
args_arr = shlex.split(args[1] and args[1] or '{args}')
lldb.target.Launch(lldb.SBLaunchInfo(args_arr), error)

it didn't fix my stuff (yet) though.. so still checking this out too

[gusc]

It's easier than that:

1. cd into source root
2. run patch -p1 < ios-deploy-1.8.6-ios10.diff

Edit:

To see if the patch was applied correctly type git diff - that should show you almost the same output as cat ios-deploy-1.8.6-io10.diff

Thanks @gusc - published 1.8.7 https://github.com/phonegap/ios-deploy/releases/tag/1.8.7

While fixing the crash this modification made it impossible to pass command line arguments to ios application. The lldb.py should read

    if len(args) > 1:
        args_arr = shlex.split(args[1])
    else:
        args_arr = shlex.split('{args}')

instead of

    if len(args) > 1:
        args_arr = shlex.split(args[1] and args[1] or '{args}')

[shazron]

@gusc can you comment on the above?

[dot-asm]

I'd like to point out that original args[1] and args[1] or '{args}' actually reads as "if args[1] exists, then pass it, otherwise pass '{args}'". Another way to see if args[1] exists is of course to see if len(args) is larger than 1. In other words after addition of explicit if first condition in original args[1] and args[1] or '{args}' is always true and as result expression is always evaluated to args[1] and never to '{args}'. So that suggested modification simply brings back the "otherwise" clause in the original conditional statement.

Well, to be honest the args handling is a bit messy in sense that one mixes indexed and non-indexed references. So that it might be appropriate to replace '{args}' with args[0] to make things clearer...

[dot-asm]

Oh! Forget that last "to be honest" remark! Despite same name '{args}' has nothing to do with args[] in the expression in question. Sorry about confusion....

[gusc]

@shazron I just tried to make as small as possible fix for an issue when args is empty or None - I can't comment on the original syntax though - it looks a little bit weird as it would be enough to write args[1] or '{args}' (without the args[1] and). I'd actually go with the @dot-asm if/else solution than the messy boolean one.

[shazron]

Alright, I'll file a new issue and put in @dot-asm's fix. I'll roll that in with the tvOS support pull request for 1.8.8

I agree, I'd rather the code be more explicit than clever :)
