My project works fine on one MacBook, but after I transfering it to another MacBook, it crashes.Here is a part of my code:func MusicPlay()
{
Playnow = true
self.ipv.start()
self.playButton.isHidden = true
self.pauseButton.isHidden = false
var path = Bundle.main.path(forResource:music!,ofType :"mp3")
if Initial == true{
path = Bundle.main.path(forResource:music!,ofType :"mp3")
}
else{
switch music {
case "Viva La Vida":
path = Bundle.main.path(forResource:"result1",ofType :"mp3")
case "Something Just Like This":
path = Bundle.main.path(forResource:"result2",ofType :"mp3")
case "Señorita":
path = Bundle.main.path(forResource:"result3",ofType :"mp3")
default:
path = Bundle.main.path(forResource:music!,ofType :"mp3")
}
}
let soundUr1 = URL(fileURLWithPath: path!)
do{
try audioPlayer = AVAudioPlayer(contentsOf: soundUr1)
audioPlayer.volume = 1.0
audioPlayer.numberOfLoops = -1
audioPlayer.delegate = self
audioPlayer.play()
} catch{
print(error)
}
}After choosing a music at tableView, it performs the function "MusicPlay",and then the project crashes at line 26:try audioPlayer = AVAudioPlayer(contentsOf: soundUr1)Error message:2020-02-15 22:47:22.013016+0800 InteractivePlayerView[6645:253620] [plugin] AddInstanceForFactory: No factory registered for id <CFUUID 0x6000004d7120> F8BB1C28-BAE8-11D6-9C31-00039315CD46What should I do to address this problem?

When I run my project,it crashes quickly,with error message:"Unknown class _TtC10Soul_Music27CollectionViewSlantedLayout in Interface Builder file.""Soul_Music" is the name of my project and "CollectionViewSlantedLayout" is a class at my project.I'm sure that there is no class called "_TtC10Soul_Music27CollectionViewSlantedLayout".How to address this problem?Thanks in advance.
I am working on show weather project. I am listing the cities from database. When I click on a city, another viewcontroller should open. But when I click on a city, the didSelectRowAtIndexPath function does not work.Here is the my code:import UIKit

fileprivate var texts = ["Los Angeles", "New York", "Chicago"]

}What should I do to make it correct?Thanks in advance.

}There is an error in SecondViewController.swift at the line 37 :return toViewControllerAnd the error message is "Cannot convert return expression of type 'DemoTableViewController' to return type 'ExpandingTableViewController' "What should I do to make it right?Thanks.
