TuistString+App can’t solve \”

Few days ago I completed migrating to Tuist an App, supporting multiple languages. But I met an error I hadn’t seen before when building the migrated project.

Argument type module does not conform to expected type ‘CVarArg’ Replace ‘,“ with “ as! CVarArg’

It seemed like referring to the Localizable.strings. This error was occured in TuistString+.swift. So it was generated by Tuist automatically.

My Localizable.string was like this.

I put double quates into the String key.

"\"WhereWeGo\" needs to use your location" = "\"WhereWeGo\" needs to use your location";

This Localizable enum enables us to access resources by code easily.

So I changed to ‘WhereWeGo’ to solve this problem.

However I was curious about why Tuist generated this Swift file.

I asked GPT ‘how to turn off strings enum generation in Tuist?’

He answered

Project(
    ...,
    resources: [
        .process("Resources"),
        .exclude("Resources/Localizable.strings") // Exclude specific files if necessary
    ],
    ...
    resourceSynthesizers: [
        .assets(),
        .fonts()
        // Exclude .strings() here to avoid generating enums for strings.
    ]
)

So what is resourceSynthesizers?
It is explained in the documentation, but not much.

So I looked into ResourceSynthesizer

It supports generations of various type of resource.

There might be various way to solve this issue, but I just remove all generation like following manifest.

Project(
    ...,
    resources: [
        ...
    ],
    ...
    resourceSynthesizers: [] // set empty to remove all default generation
)

I could exclude Localizalbe.strings file, but my app requires it.

resources: [
    .process("Resources"),
    .exclude("Resources/Localizable.strings") // Exclude specific files if necessary
],

See you later.

Happy Tuisting!
