}This solution uses SwiftUI with PHPickerViewController to let users pick a photo from their device. The selected photo is shown as a preview image below the Select Photo button.
The Upload button is disabled if no photo is selected or if an upload is in progress. When Upload is tapped, a timer simulates upload progress by increasing a progress value every 0.1 seconds. The progress percentage is shown as text.
When upload completes, a confirmation message appears. The photo picker is presented as a sheet. This approach keeps UI responsive and simple for beginners.
