Check object or any value is null or not with its availability. This demo checks the nullability of any object or value which may come from API response and handle it properly accordingly. This demo is specially used in Swift programming language.
It's called nil in Swift which means the absence of a valid object.
- Xcode 10.0 or above
- Swift 4.0 or above
You just need to download this demo and run it inot SIMULATOR or REAL device whatever you want. OR Just copy and paste code from Utility.swift file into your projects and access it!
Utility code for check nil value or nil object is:
static func isObjectOrValueAvailable(someObject: Any?) -> Any?
{
if someObject is String {
if let someObject = someObject as? String {
return someObject
} else {
return ""
}
} else if someObject is Array<Any> {
if let someObject = someObject as? Array<Any> {
return someObject
} else {
return []
}
} else if someObject is Dictionary<AnyHashable, Any> {
if let someObject = someObject as? Dictionary<String, Any> {
return someObject
} else {
return [:]
}
} else if someObject is Data {
if let someObject = someObject as? Data {
return someObject
} else {
return Data()
}
} else if someObject is NSNumber {
if let someObject = someObject as? NSNumber{
return someObject
} else {
return NSNumber.init(booleanLiteral: false)
}
} else if someObject is UIImage {
if let someObject = someObject as? UIImage {
return someObject
} else {
return UIImage()
}
} else {
return "NoObjectORValueAvailable"
}
}Using below if-else condition esily find object or value nil or not & if it's not proper it will handle with default initialized value:
let intValue: Int? = nil // some integer value but null
if "\(Utility.isObjectOrValueAvailable(someObject: intValue as AnyObject)!)" != "NoObjectORValueAvailable" {
print("Value found")
// do your stuff with value
} else {
print("Value not found!")
// handle stuff here if no integer found
