Guides day-to-day work in Tuist-generated Xcode workspaces, including generation, build and test commands, and buildable folders. Use when working in a Tuist-generated project or when users mention `tuist generate`, `xcodebuild test`, or generated workspaces.

Using Tuist Generated Projects

Quick Start

bash

# Generate workspace without opening Xcode
tuist generate --no-open

# Build a scheme with xcodebuild
xcodebuild build -workspace App.xcworkspace -scheme App

# Run tests with xcodebuild
xcodebuild test -workspace App.xcworkspace -scheme AppTests -only-testing AppTests/MyTestCase

Project definition

Prefer buildable folders

Use

buildableFolders

instead of

sources

and

resources

globs. Buildable folders stay synchronized with the file system, so adding or removing files does not require regeneration.

swift

let target = Target(
  name: "App",
  buildableFolders: [
    "App/Sources",
    "App/Resources",
  ]
)

Tag targets for focus

Use target tags to group areas of the project, for example:

```
tag:team:*
```
```
tag:feature:*
```
```
tag:layer:*
```

These tags make it easier to scope generation and testing later.

Example target metadata with tags:

swift

let target = Target(
  name: "PaymentsUI",
  metadata: .metadata(tags: [
    "tag:team:commerce",
    "tag:feature:payments",
    "tag:layer:ui",
  ])
)

When working on a focused area, generate only what you need:

bash

tuist generate tag:feature:payments
tuist generate PaymentsUI PaymentsTests

Align build configurations

Keep build configurations aligned between the project and external dependencies. Use

PackageSettings(settings: .settings(configurations: []))

to mirror project configurations; mismatches emit warnings.

Workflows

Generate intentionally

Use
```
tuist generate --no-open
```
in automation and scripts to avoid launching Xcode.
Regenerate when any manifest changes (or the dependency graph changes).
If generation fails due to missing products, run
```
tuist install
```
to resolve dependencies and retry.

Build with xcodebuild

Use

xcodebuild build

against the generated workspace and scheme.

bash

xcodebuild build \
  -workspace App.xcworkspace \
  -scheme App \
  -destination "generic/platform=iOS Simulator"

Test with xcodebuild

Use

xcodebuild test

for running tests locally. Prefer it over

tuist test

because

tuist test

regenerates the project on each invocation, which slows down iteration.

To optimize test run time:

Use
--only-testing
to run only the specific test suite or test case you are working on, instead of the full target.
Pick the scheme with the fewest compilation targets that still includes the test target you need. This minimizes build time before tests run.

bash

# Run a specific test suite
xcodebuild test \
  -workspace App.xcworkspace \
  -scheme AppTests \
  -only-testing AppTests/MyTestSuite

# Run a single test case
xcodebuild test \
  -workspace App.xcworkspace \
  -scheme AppTests \
  -only-testing AppTests/MyTestSuite/testMyFunction

Guidelines

Keep
```
buildableFolders
```
paths aligned to the target's real file system layout.
Avoid overlapping
```
buildableFolders
```
with
```
sources
```
or
```
resources
```
globs in the same target.
Open Xcode manually when needed after running
```
tuist generate --no-open
```
.

Troubleshooting

Static side effects warnings: adjust product types deliberately. Use

Target.product

for local targets and

PackageSettings(productTypes:)

for external products. Making everything dynamic with

.framework

can compile and run, but it may hurt launch time. Prefer static products (static frameworks or libraries) when possible and when they do not introduce side effects.

Objective-C dependency crashes: add

-ObjC

or

-force_load

via

OTHER_LDFLAGS

on consuming targets as needed. Reference:

https://docs.tuist.dev/en/guides/features/projects/dependencies#objectivec-dependencies
