# architecture

The architecture version of the app to launch.

## Declaration

```swift
var architecture: cpu_type_t { get set }
```

## Discussion

Discussion The default value of this property is CPU_TYPE_ANY, which causes the system to launch the app’s preferred architecture. You may specify a different value to force the system to launch that architecture. For a list of possible types, see the <mach/machine.h> header file.
