Cannot convert return expression of type SignalProducer<UIImage, AnyError>

Hello,

I have taken error message from return expression below blocks

func imageProducer(for photo: Photo) -> SignalProducer<UIImage,NSError>    {
    let request = URLRequest(url: URL(string: photo.imageURL)!)
    let signal = URLSession.shared.reactive
        .data(with: request)
        .observe(on: ImmediateScheduler())
        .map { (data, response) -> UIImage in
            return UIImage(data: data)!
        }
    return signal
}

my pod details.

target 'MarsRover' do # Comment the next line if you're not using Swift and don't want to use dynamic frameworks use_frameworks!

# Pods for FRP-Login
pod 'ReactiveSwift', :git => 'https://github.com/ReactiveCocoa/ReactiveSwift.git', :tag => '1.0.0'
pod 'ReactiveCocoa', :git => 'https://github.com/ReactiveCocoa/ReactiveCocoa.git', :tag => '5.0.0'
pod 'Result', :git => 'https://github.com/antitypical/Result.git', :tag => '3.1.0'

end

post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['SWIFT_VERSION'] = '3.0' end end end

You just need to change NSError to AnyError. If it does not work, try to get latest version of ReactiveCocoa and ReactiveSwift
