The discussion about iOS indie app development revolves around various challenges and opinions on Apple's Swift programming language and its frameworks, particularly SwiftUI. There are concerns about the performance and reliability of the Swift compiler, with comments criticizing its tendency to time out. Additionally, users express frustration with SwiftUI, describing it as bug-ridden and lacking compatibility with other systems, like PhotosUI. This leads to a conversation about whether developers should focus on native system features, such as password protection or hidden albums, instead of relying on potentially flawed frameworks. Overall, the sentiment is skeptical about the current tools offered by Apple for indie developers.
