Thank you both for your responses. I do need to bone up on how to use optionals. Point taken. One question regarding converting to binary. Would you explain more why I cannot convert "27" . Is there a method to convert integers to binary. Thanks for your help. And I really like the new forums.xc

I found this to work, but is it the best method? let myNewNumber = 12345 if let myBinary = Int(String(myNewNumber, radix: 2)) {     print(myBinary) } else {     print("Bad input as binary: \(myNumber)") }

Hi again. I'm confused by the following: let myNumber = 12345 if let myHex = Double(String(myNumber, radix: 16)) {     print(myHex) } else {     print("Bad input as hexadecimal: \(myNumber)") } That works well. However, if I change myNumber to 1234, I get the Bad Input message.

Still there for me using MapKit, Swift 5, Xcode 12.3. (12C33).

Has anyone tries CocoaPods in Xcode 14 beta 5 (14A5294e)? I get a stew of errors when using: 1: sudo arch -x86_64 gem install ffi 2: arch -x86_64 pod install pod install Ignoring ffi-1.15.3 because its extensions are not built.

Thanks for your reply! It makes sense, however the two functions are still not called.

Got it. I forgot to override viewWillDisappear

Same situation on two computers, an M1 MacMini and an M2 MacBook Pro. Using an iPhone 12 as my test device. I've followed directions here and in other threads. No joy. I don't think i can step back to Xcode 14 as my devices would not be recognized. I've submitted a report to Apple.

hi, has anyone solved this? My trouble started with XCode 15.3 beta 1
