| Here's an example | In Action |
|---|---|
| Define search for GitHub repositories ... |  |
let searchResults = searchBar.rx.text.orEmpty
.throttle(.milliseconds(300), scheduler: MainScheduler.instance)
.distinctUntilChanged()
.flatMapLatest { query -> Observable<[Repository]> in
if query.isEmpty {
return .just([])
}
return searchGitHub(query)
.catchAndReturn([])
}
.observe(on: MainScheduler.instance) |
|
| ... then bind the results to your tableview | |
searchResults
.bind(to: tableView.rx.items(cellIdentifier: "Cell")) {
(index, repository: Repository, cell) in
cell.textLabel?.text = repository.name
cell.detailTextLabel?.text = repository.url
}
.disposed(by: disposeBag) |
### [Carthage](https://github.com/Carthage/Carthage)
Add this to `Cartfile`
```
github "ReactiveX/RxSwift" "6.2.0"
```
```bash
$ carthage update
```
#### Carthage as a Static Library
Carthage defaults to building RxSwift as a Dynamic Library.
If you wish to build RxSwift as a Static Library using Carthage you may use the script below to manually modify the framework type before building with Carthage:
```bash
carthage update RxSwift --platform iOS --no-build
sed -i -e 's/MACH_O_TYPE = mh_dylib/MACH_O_TYPE = staticlib/g' Carthage/Checkouts/RxSwift/Rx.xcodeproj/project.pbxproj
carthage build RxSwift --platform iOS
```
### [Swift Package Manager](https://github.com/apple/swift-package-manager)
> **Note**: There is a critical cross-dependency bug affecting many projects including RxSwift in Swift Package Manager. We've [filed a bug (SR-12303)](https://bugs.swift.org/browse/SR-12303) in early 2020 but have no answer yet. Your mileage may vary. A partial workaround can be found [here](https://github.com/ReactiveX/RxSwift/issues/2127#issuecomment-717830502).
Create a `Package.swift` file.
```swift
// swift-tools-version:5.0
import PackageDescription
let package = Package(
name: "RxTestProject",
dependencies: [
.package(url: "https://github.com/ReactiveX/RxSwift.git", .exact("6.2.0"))
],
targets: [
.target(name: "RxTestProject", dependencies: ["RxSwift", "RxCocoa"])
]
)
```
```bash
$ swift build
```
To build or test a module with RxTest dependency, set `TEST=1`.
```bash
$ TEST=1 swift test
```
### Manually using git submodules
* Add RxSwift as a submodule
```bash
$ git submodule add git@github.com:ReactiveX/RxSwift.git
```
* Drag `Rx.xcodeproj` into Project Navigator
* Go to `Project > Targets > Build Phases > Link Binary With Libraries`, click `+` and select `RxSwift`, `RxCocoa` and `RxRelay` targets
