# Swift MMIO
**Swift MMIO** is an open source package for defining and operating on memory mapped IO directly in Swift.
## Overview
Swift MMIO makes it easy to define registers directly in Swift source code and manipulate them in a safe and ergonomic manner.
## Example Usage
```swift
@RegisterBlock
struct Control {
@RegisterBlock(offset: 0x0)
var cr1: Register
@RegisterBlock(offset: 0x4)
var cr2: Register
}
@Register(bitWidth: 32)
struct CR1 {
@ReadWrite(bits: 12..<13, as: Bool.self)
var en: EN
}
let control = Control(unsafeAddress: 0x1000)
control.cr1.modify { $0.en = true }
```
## Using Swift MMIO in your project
Swift MMIO supports use with the Swift Package Manager. First, add the Swift MMIO repository to your Package's dependencies:
```swift
.package(url: "https://github.com/apple/swift-mmio.git", from: "0.0.2"),
```
Second, add the `MMIO` library to your target's dependencies:
```swift
.target(
name: "DeviceRegisters",
dependencies: [
.product(name: "MMIO", package: "swift-mmio")
]),
```
Finally, `import MMIO` in your Swift source code.
### Source Stability
This project follows semantic versioning. While still in major version `0`, source-stability is only guaranteed within minor versions (e.g. between `0.0.3` and `0.0.4`). If you want to guard against potentially source-breaking package updates, you can specify your package dependency using `.upToNextMinor(from: "0.0.2")` as the requirement:
```swift
.package(url: "https://github.com/apple/swift-mmio.git", .upToNextMinor(from: "0.0.2")),
```
## Documentation
For guides, articles, and API documentation see the [Package's documentation on the Web][docs] or in Xcode.
