ios-deploy: Unable to locate DeviceSupport directory

[drewwarren]

Steps to Reproduce

I was attempting to flutter run with xcode 7.2.something and I would see

Starting debug of iPhone 5s (GSM) 'drewwarren’s iPhone' (4127c6ffa53f153512916da5fe2a3afac8d23798) connected through USB...
2016-06-02 11:17:59.787 ios-deploy[4022:2958268] [ !! ] Unable to locate DeviceSupport directory. This probably means you don't have Xcode installed, you will need to launch the app manually and logging output will not be shown!
Could not install ios/.generated/build/Release-iphoneos/Runner.app on 4127c6ffa53f153512916da5fe2a3afac8d23798.
Error running application on drewwarren’s iPhone.

This says I might not have Xcode installed, but I did. flutter doctor made everything look okay for Xcode.

When I was in this state if I attempted to open FlutterApplication.xcodeproj in Xcode and click the play button I would see Could not find Developer Disk Image.

I get the same issue, but I'm using the latest version of XCode. When I try to run it in XCode, I get a white screen on my device and this in XCode. Weird thing is that it was working the other day.

@smrtsmrf can you check whether you're using Xcode 8.3.3? If so, it appears Xcode has changed the format it uses for the iOS DeviceSupport directory which is causing ios-deploy (one of our dependencies for launching iOS apps on devices) to get confused.

Upstream ios-deploy issue is: ios-control/ios-deploy#292

We can see what's in the iOS device support dir via:

ls "$(xcrun --sdk iphoneos --show-sdk-platform-path)/DeviceSupport"

With Xcode 8.3.3, I see:

drwxrwxr-x   4 cbracken  eng  136  2 Feb 07:28 9.3/

Looks like a quick hacky fix is:

cd "$(xcrun --sdk iphoneos --show-sdk-platform-path)/DeviceSupport"
ln -s 10.3.1\ \(14E8301\) 10.3

If you installed Xcode via the App Store (in which case, these files will all be owned by root), you may get a permission denied error and may need to run ln as root:

sudo ln -s 10.3.1\ \(14E8301\) 10.3

@cbracken thanks, that did the trick. 👍

Thanks for confirming! Will keep this issue open for reference until a fix goes into ios-deploy.
