How create complex ui interface in swift ?
Hi. How can we set structure complex in ui. For example, if we imagine have app's main content contains some ui - different collection views, another sections and end of all we have comments which is shows another page's bottom area. I think I'll solve it with creating different viewcontrollers - one for collection views, another for comment section... and with addchild i'll add all of that to Main controller. Is this way is well ? CommentController which is gets comments and adding that section to some controller what i want. is this right ?

Adding AppTrackingTransparency problem
Guideline 5.1.2 - Legal - Privacy - Data Use and Sharing The app privacy information you provided in App Store Connect indicates you collect data in order to track the user, including Crash Data. However, you do not use App Tracking Transparency to request the user's permission before tracking their activity. Starting with iOS 14.5, apps on the App Store need to receive the user’s permission through the AppTrackingTransparency framework before collecting data used to track them. This requirement protects the privacy of App Store users. I am getting this rejected message from apple. But I added AppTrackingTransparency to my project and alerts when the app launches. What must I do for the next step? P.s I am using Firebase's Crashlytics. struct AppDelegateHelper {   static func askAppTrackingTransparency() {     // Request user authorization to access app-related data for tracking the user or the device.     if #available(iOS 14, *) {       ATTrackingManager.requestTrackingAuthorization { status in         switch status {         case .authorized:           print("Allowed to AppTrackingTransparency")           break                     case .denied: break         case .notDetermined: break         case .restricted: break         }       }     } else {       // Fallback on earlier versions       print("Can't ask AppTrackingTransparency")     }   } }

Binding multiple data and cells in RxSwiftDataSource
I'm trying to show multiple cells and their own data models in the same tableView. I added segment control for this and I delete all tableview current data and removed the current data sources and binding new data and its cell. But I am getting the below error message :( If you have any offers please help me :( P.s: Each segment's cells and sections design is different than each other.

HMAC<SHA256> in swift
I have 2 apps, I use HMAC for signature between apps. First App's minimum deployment target is 11.2 and it uses CryptoSwift for sending data to the second app while signing documents. But the Second app uses Apple's CryptoKit, and I get a signing error. Can I use different packages for HMAC Sha256 process?

Trading charts tool integration
Hello developers, I'm currently working on an iOS application that requires trading chart functionality, and I'm looking for a solution that I can easily integrate into my app. I've heard about TradingView's charting and technical analysis tools, but I'm not sure if they offer a library that I can use. Can anyone recommend a charting tool that is easy to integrate into an iOS app? Ideally, the tool should offer real-time data streaming, support for multiple chart types, and customizable indicators and drawing tools. Any suggestions or recommendations would be greatly appreciated. Thank you!
