### Building content

[`buildBlock()`](/documentation/SwiftUI/CommandsBuilder/buildBlock())

Builds an empty command set from a block containing no statements.

[`buildBlock(_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:))

Passes a single command group written as a child group through
modified.

[`buildBlock(_:_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:_:))

[`buildBlock(_:_:_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:_:_:))

[`buildBlock(_:_:_:_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:_:_:_:))

[`buildBlock(_:_:_:_:_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:_:_:_:_:))

[`buildBlock(_:_:_:_:_:_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:_:_:_:_:_:))

[`buildBlock(_:_:_:_:_:_:_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:_:_:_:_:_:_:))

[`buildBlock(_:_:_:_:_:_:_:_:)`](/documentation/SwiftUI/CommandsBuilder/buildBlock(_:_:_:_:_:_:_:_:))

### Building conditionally

[`buildEither(first:)`](/documentation/SwiftUI/CommandsBuilder/buildEither(first:))

Produces content for a conditional statement in a multi-statement closure
when the condition is true.

[`buildEither(second:)`](/documentation/SwiftUI/CommandsBuilder/buildEither(second:))

Produces content for a conditional statement in a multi-statement closure
when the condition is false.

[`buildIf(_:)`](/documentation/SwiftUI/CommandsBuilder/buildIf(_:))

Produces an optional widget for conditional statements in multi-statement
closures that’s only visible when the condition evaluates to true.

[`buildLimitedAvailability(_:)`](/documentation/SwiftUI/CommandsBuilder/buildLimitedAvailability(_:))

Processes commands for a conditional compiler-control statement that
performs an availability check.

[`buildExpression(_:)`](/documentation/SwiftUI/CommandsBuilder/buildExpression(_:))

Builds an expression within the builder.
