Jenkins Workspace structure - ios

I have a project for iOS which I am trying to make it a part of a Continuos Integration. Apparently, every time I try to compile the project it gives me an error of cannot locate the file.
The structure of the entire directory is as following
ABC/test2/Feed/xcodeproject.xcodespace
So hence in SVN my url is as following:
www.company.com/trunk/
where after trunk the entire directory of ABC gets downloaded, and the structure of the application is correct. However when I am trying to build the application
xcodebuild ARCHS=i386 ONLY_ACTIVE_ARCH=NO -target "ABC" -configuration
Release -sdk iphonesimulator
Now the content of ABC project is lying within /ABC/test2/Feed/ directory, hence the error is generated is The directory "xyz" does not contain an Xcode project.
If I go another approach using svn as www.company.com/trunk/ABC/test2/Feed/
then some files within the structure doesn't lays correctly and says the files are missing and fails to build.
How can I fix the first scenario which I bet is the easier fix for all of this in Jenkins Configure?
Thanks

xcodebuild default build path

I'm trying to make a FAT framework following this guide
What I'd like to understand is the xcodebuild build path. Based on that tutorial, this is created at the beginning:
BUILD_PATH="${SRCROOT}/build"
Now when I make a build, the builds for Release-iphoneos and Release-iphonesimulator go into that build folder. Is this a predefined variable that can be set to tell Xcode where your builds can go? Because based on this other tutorial: BUILD_DIR gets passed to xcodebuild.
I was wondering what the difference is here and how Xcode handles these arguments.
How does setting this directory work with DerivedData?
Also on the topics of building, does Xcode cache builds? Sometimes after I build and do a ls -al on my frameworks, they don't have current timestamps. But once I delete the build directory, it seems to force Xcode to build again and then I get "fresh" frameworks created. Is Xcode caching the build and not replacing the build? Is there a way to force it?

What could cause code coverage enabled builds to fail?

Summary
I'm trying to get a code coverage report from my project. However when I try to build and run tests, there is no CodeCoverage folder created in the derived data folder.
How am I trying to do this?
I am running xcodebuild as follows:
xcodebuild \
-workspace <some_workspace> \
-scheme <some_scheme> \
-destination <some_destination> \
-derivedDataPath <some_path> \
-enableCodeCoverage YES \
build test
What is the problem?
For my workspace/project it fails at the very end with a line:
xcodebuild: error: Failed to build workspace <some_workspace> with scheme <some_scheme>.
Reason: Could not determine bundle identifier for <some_test_target>'s TEST_HOST: "<some_path>/Build/Intermediates/CodeCoverage/Products/Debug-iphonesimulator/<some_product>.app"
At first it seemed directly linked to the TEST_HOST issue, but that's not the case here.
There is simply no CodeCoverage folder:
<some_path>/Build/Intermediates/CodeCoverage
What have I tried?
I tried the same with a clean new project, same running the same xcodebuild command, which succeeds. Within the Build/Intermediates/ folder exists the CodeCoverage folder.
However, in my own project, which is more complex, the Build/Intermediates/ folder contains a bunch of *.build folders (related to the app and the various frameworks, HockeySDK.build for example) and PrecompiledHeaders but no CodeCoverage folder.
When looking through the output of xcodebuild I never see a reference to the CodeCoverage folder for my project. However, for the test project, the first mention is at:
Write auxiliary files
/bin/mkdir -p /<some_path>/Build/Intermediates/CodeCoverage/Intermediates/<some_project>.build/Debug-iphonesimulator/<some_project>.build/Objects-normal/x86_64
For my project I see:
Write auxiliary files
/bin/mkdir -p /<some_path>/Build/Intermediates/<some_project>.build/Debug-iphonesimulator/<some_project>.build/Objects-normal/x86_64
Workaround
Something else that seemed to 'trick' it into working is to set the Host Application to None. After doing this it builds and tests, but tests fail due to the lack of host. However, this causes the CodeCoverage folder to be created, and if the Host Application is correctly set again, running the build and tests works fine, with a code coverage report produced.
You have to assure the package name is equal in all configurations. Xcode modifies it in case you are using unsupported characters. For instance Xcode replaces "-" with "_".
In all configurations, go to:
Project -> Build Settings -> Product Module
and set the exact same name without spaces.

xcodebuild linker failing when custom output directory provided

I have a problem using xcodebuild to build the iOS app to custom directory.
Everything works well if I am building using command:
xcodebuild -workspace MyWorkspace.xcworkspace -scheme MyAppScheme -sdk iphoneos -configuration Release ONLY_ACTIVE_ARCH=NO
...but I would like the .app and .dSYM files to be saved in a specific directory (./build for example). So, I tried adding:
CONFIGURATION_BUILD_DIR=./build
or
OBJROOT=./build SYMROOT=./build
as a xcodebuild parameters. Then I've got this error (output comes from xctool as it's more readable, but the same error occurs when using xcodebuild):
✗ Link MyApp
(...)
ld: library not found for -lPods-MyApp-SomePodName
clang: error: linker command failed with exit code 1 (use -v to see invocation)
As I am using Cocoapods, my workspace contains app's project and "Pods" project. I tried using xcodebuild on several other projects that uses Cocoapods and I am always getting this error (SomePodName differs depending on project's dependencies) when trying to provide custom output directory. Please note, that it works without an issue when CONFIGURATION_BUILD_DIR, OBJROOT and SYMROOT parameters are skipped.
I wonder if anything changed recently, because I am pretty sure that I was able to build to custom directory using xcodebuild in the past. Currently, Travis-CI is still able to do it without an issue, but I have no luck when trying on my local machines.
Perhaps providing CONFIGURATION_BUILD_DIR, OBJROOT or SYMROOT is not the perfect way for specifying custom output directory. I am not sure if the problem is connected directly to Cocoapods, but the errors are always connected with some pod library.
Any hints will be appreciated.
My environment:
OS X 10.10.3
Xcode 6.3
xctool 0.2.3
cocoapods 0.36.3
Update: Problem solved
It looks like xcodebuild requires absolute path for CONFIGURATION_BUILD_DIR, OBJROOT and SYMROOT parameters.
Providing absolute path solved the problem:
CONFIGURATION_BUILD_DIR=/Users/me/Dev/MyApp/build

Why when generating .app file, xcode needs to be open?

I'm writing a script to build and generate an .app file from an specific target and scheme (to work with simulator). I was using something like:
DEVELOPER_DIR=$xcode_app_path/Contents/Developer xcodebuild -sdk iphonesimulator -scheme "${SCHEME}" -target "${TARGET}" ONLY_ACTIVE_ARCH=NO CONFIGURATION_BUILD_DIR="${build_folder}" clean build
The problem is, that I need to open XCode for the code above to work, otherwise will show me a message telling me that:
xcodebuild: error: The project 'Project-name' does not contain a scheme named "${SCHEME}"
I still yet, don't understand what is XCode doing in background. But if I open the IDE and run the script, works. If I open and later close it, and run the script works. It's not working if the project hasn't been opened first with XCode ¬¬
Any suggestion would be appreaciated
If someone is facing the same experience, this is what I found out. And works.
Well, apparently when you create a new scheme through command line, by default is not "shared". So when you start to link to the folder
xcshareddata --> xcschemes
(trying to build with command line, for example) there's nothing to link with. Xcode do this automaticaly under the hood when you open your project...
The guys from CocoaPods were facing the same issue, so they created a Ruby gem that shares the scheme and place the file in his xcscheme folder:
This is the repo: https://github.com/CocoaPods/Xcodeproj
Also, thanks to this post and this post I found out how to use xcodeproj gem, and change the shared option with a script that I put downhere:
require 'xcodeproj'
xcproj = Xcodeproj::Project.open("MyProject.xcodeproj")
xcproj.recreate_user_schemes
xcproj.save

Xcode commandline building with dependent project

I'm building a iOS application that uses a library that I've built using jverkoey's framework structure. All is well and good, until I try to let my CI environment (Jenkins) build my project. Jenkins builds using the commandline and when it does so my dependent framework gets built in it's own build directory, and when my main application builds in it's own directory it can't find the framework.
As a test I copied the output from my dependent frameworks build directory into the main apps build directory and re-ran my commandline build and everything works fine. So what I think I have to do is update my Jenkins build scripts to be able to move the dependent build output before building the main app, or change them to all build in the same directory as XCode does from the IDE with it's DerivedData directory.
The question is, how? I'm no expert when it comes to building from the commandline and I could really use some help here.
Ok, I figured this out. Just incase anyone else has a similar problem you can set the SYMROOT setting to whatever directory you want when running xcodebuild.
xcodebuild -target MyTarget SYMROOT=/Build/MyProj/Sym.root
