Hi, Please check attached code. **SwiftSampleApp** Import pictures from Flickr Import from photo library Import from camera capture. Add text for image. Multiselect images from library and flickr API. Share picture url on social media. **NOTE** Flickr : Since there are lot of images on flickr, I have restricted it to 20 items. I havent added any pagination to it. Since its a proof of concept. I have appended URL parameter directly in API class. Usually I dont this way, but since this is POC, I made exception. I have added loader to load images from flickr. You can only share images imported from flickr API since it has shareable URI. If you want me to add faebook and other sdks, I can do that. I still have time. I have used UIActivityViewController for convience. You might have to test this on device. Photo Library: Please note that I have limited the photo import to 100 images. Since it's lot of load on app due to heavy image play. Also note that since this is POC. I havent implemented async image download. To avoid load on app, restricted image selection for two at a time. Sometimes, there is error in loading large image, in that case you will view a flower png which is placeholder image. Since this was not mentioned in the doc, but I have added extra feature of adding text with images, also added multiple image support. **Architecture** I have used MVVM and RxSwift to achieve MVVM architecuture. I have demoed using collection view through RxSwift on HomeViewController. I have used normal swift in other classes. You can check more about RxSwift here : https://github.com/ReactiveX/RxSwift I have done mapping from JSON to object using ObjectMapper. I have created the photo library UI entirely myself. You can check it. I have used photos and combination of open source library imagePicker. I have used imagePicker for Camera and used some of its element in Photo libray. **Test** I have tested this app on iPhone6 device and used simulator for the other device test. I have also added UI Automation test. Please check that as well. **Code ethics** I have tried to put best methods forward and tried achieveing encapsulation and abstraction. **UI** UI is pretty simple. I havent really involved much of time in making jazzy UI. But UI is very neat and clean. In case better UI is required I can do that as well. **edge cases** Since this is POC I have ignored some test scenarios. If you want me to cover those I can do as well.
