Add support for Xcode 8.3

[jamessharp]

iOS only (tns 2.5.3)

Xcode 8.3 has fully removed the ability to do an xcrun PackageApplication as is performed when building/running a nativescript app on a development device (see this line of code here). This means that tns run ios and friends don't work under Xcode 8.3, failing with the following error:

xcrun: error: unable to find utility "PackageApplication", not a developer tool or in PATH
Command xcrun failed with exit code 72

Some googling around has suggested moving to using xcodebuild, and the cordova guys have done the update in this PR: apache/cordova-ios#257

Let me know if you need any further info

Any feedback on this? Specially on how to fix would be really much appreciated!

It happens on my machine as well and now I'm unable to run apps on my iOS device... This is really a deal-breaker!

Fix will be available in 3.0.0 and we will also release hot fix for {N} 2.5.* as soon as issue is fixed.

and we will also release hot fix for {N} 2.5.*

Really glad to hear that because we're close to release of an app and we wont have the time for an update to 3.0.0. I'm sure we're not alone with this scenario.

Same...

As a temporary workaround, you can still build and run your app by opening workspace in XCode directly. Especially for the release purposes.

@dunqan Thank you for that hint. By the way: The run command seems to work just fine with the iOS emulator. (Which helps shorten the dev-times compared to the Xcode workspace route if features can be tested within the emulator)

Is it possible to downgrade XCode back to 8.2 and would that solve current problems?

[CitySim]

Yes, you downloaded XCode 8.2 from https://developer.apple.com/download/more/
tns build works again for me now

[dtopuzov]

You can have both Xcodes installed and switch them with xcode-select, example:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

Please also run xcodebuild -version after that to verify switch is successful.
