Making sure a .post action is executed last as BuildPhase

[parse]

Describe the bug
First of all, thanks for the amazing work you've done on Tuist. I started working on an app yesterday and its moving along quite nicely.

I have an issue with adding Fabric as the last build phase step. According to Pedro (on twitter, https://twitter.com/pedropbuendia/status/1174655179129536512?s=20) any action I've added should be added last. I find that is not necessarily the case.

To Reproduce
Steps to reproduce the behavior:

Add a step such as:

actions: [
    .post(
      path: "./Scripts/fabric.sh",
      arguments: [],
      name: "Fabric",
      inputPaths: ["$(SRCROOT)/$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)"]
    )
  ],

For context, this is my entire target:

let obfuscatedName = Target(
  name: "obfuscatedName",
  platform: .iOS,
  product: .app,
  productName: "obfuscatedName",
  bundleId: "obfuscatedName",
  infoPlist: "Profiles/obfuscatedName/Info.plist",
  sources: ["Sources/**"],
  resources: [
    "Profiles/obfuscatedName/Resources/LaunchScreen.xib",
    "Profiles/obfuscatedName/Resources/Images.xcassets",
    "Profiles/obfuscatedName/Resources/GoogleService-Info.plist"
  ],
  actions: [
    .pre(path: "./Scripts/swiftlint.sh", arguments: [], name: "Swiftlint"),
    .post(
      path: "./Scripts/fabric.sh",
      arguments: [],
      name: "Fabric",
      inputPaths: ["$(SRCROOT)/$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)"]
    )
  ],
  dependencies: [
    .target(name: "MobileOrderCore"),
    .cocoapods(path: ".")
  ]
)

Expected behavior
I expect the action to get added last to the list.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: MacOSX
• Version [e.g. 22] OSX: 10.14.5, tuist: 0.17.0

Additional context
I am running Cocoapods, not sure if that has any impact.

This is the output from the build step, (i.e. Fabric):

warning: DEBUG_INFORMATION_FORMAT should be set to dwarf-with-dsym for all configurations. This could also be a timing issue, make sure the Fabric run script build phase is the last build phase and no other scripts have moved the dSYM from the location Xcode generated it.
