How to pass build settings

[shurale85]

Hi!
I have two .xccongif files for release and debug. Both files contain of setting for SWIFT_ACTIVE_COMPILATION_CONDITIONS
like

1. SWIFT_ACTIVE_COMPILATION_CONDITIONS=DEBUG PUBLIC (for debug)
2. SWIFT_ACTIVE_COMPILATION_CONDITIONS=PUBLIC OTHER (for release)
   It is ok with setting for release after generating project. But debug configuration is missing setting from xcconfig file. Paths to congifs are right.
   So I dodn't understand why settings are not applied for debug configuration. I feel that no changes in my .xcconfig file are applied for debug configuration

So I tried to pass settings in my manifest file like below and finally I got my settings for debug configuration was fine.
let setting = Settings.settings(configurations: [ .debug(name: "Debug", settings: ["SWIFT_ACTIVE_COMPILATION_CONDITIONS" : ["DEBUG", "PUBLIC"]], xcconfig: "Configs/Debug.xcconfig"), .release(name: "Release", xcconfig: "Configs/Release.xcconfig") ])

What is the right way to pass settings? Why settings may or may not be applied depending on configuration type?
Thanks you!

Hi @shurale85

SWIFT_ACTIVE_COMPILATION_CONDITIONS is one of the build settings Tuist has a default for in debug at the target level. This ends up taking precedence over any defined in the xcconfig sadly and that is why only the release configuration is working in your first attempt.

In terms of how to set the setting in Tuist, you have a few options

• (1) The first is the one you already discovered, which is explicitly specifying them in Settings within the Project.swift manifest at the target level which takes precedence over the tuist defaults (but does mean the setting in the xcconfig would be redundant)

• (2) Another would be to exclude SWIFT_ACTIVE_COMPILATION_CONDITIONS from the list of default settings Tuist provides via using the defaultSettings API and thus ensuring the value you specify in xcconfig is respected

let settings: Settings = .settings(
    configurations: [
        .debug(name: "Debug", xcconfig: "Configs/Debug.xcconfig"),
        .release(name: "Release", xcconfig: "Configs/Release.xcconfig"),
    ],
    defaultSettings: .recommended(excluding: ["SWIFT_ACTIVE_COMPILATION_CONDITIONS"])
)

let project = Project(
  // ...
  settings: settings,
  targets: [
     // ...
  ]
)

hope this helps

Soulds like a solution. Only question is that info documented anywhere except source code?)
