Has anyone attempted to build a metawear app using mostly SwiftUI?

  But swiftUI is just a UI library. It has nothing to do with our sensors and APIs. I don't know why it would be mentioned in the forum at all.

  @Ben_R...

  We're building a Swift SDK using Combine. It's less verbose, ditches Bolts, and requires no unsafe Swift.

  We're wrapping up a tutorial series with SwiftUI demo apps. Given your SwiftUI work, I'd love to hear your reaction to the current draft. Reading is a bit smoother in Xcode's doc browser, but the HTML version is fine. To use Xcode, double click a DocC archive here or clone the SDK package and press Control Shift CMD D to build the docs.

  For flavor, here’s a snippet logging a variant selection of sensors.

  downloadPipeline = metawear
      .publishWhenConnected()
      .first()
      .optionallyLog(configs.accelerometer)
      .optionallyLog(configs.gyroscope)
      .optionallyLog(configs.quaternion)
      .sink(receiveCompletion: { [weak self] in
          self?.displayError(ifFound: $0)
      }, receiveValue: { [weak self] in
          self?.offerDownloadCallToAction()
      })
  
  metawear.connect()
  

  Here’s a snippet that flashes the LEDs in purple or blue when pressing or releasing the MetaWear button.

  macroSub = metawear?
      .publishWhenConnected()
      .first()
      .command(.macroStartRecording(runOnStartup: true))
      .recordEvents(for: .buttonUp, { recording in
          recording.command(.ledFlash(.Presets.eight.pattern))
      })
      .recordEvents(for: .buttonDown, { recording in
          recording.command(.ledFlash(.Presets.zero.pattern))
      })
      .command(.macroStopRecordingAndGenerateIdentifier)
      .sink(receiveCompletion: { _ in }, receiveValue: { _ in })
  
  metawear?.connect()
