Swift Put String to Array from one to all letters
(5 answers)
Closed 2 years ago.
I have a string with no spaces I would like to turn the string into an array.
Let's say the string is "guru1", I would like my array to be ["g", "gu", "gur", "guru", "guru1"]
Thanks in advance.
You can use reduce :
"guru1".reduce([]) { $0 + [($0.last ?? "") + "\($1)"] }

How to capitalize each word in a string using Swift iOS
(8 answers)
Closed 5 years ago.
How can i capitalized each first letter of the result of this
self.namE.text = currentUser.displayName
self.handle.text = snapshotValue?["handle"] as? String
instead of "Bruce willis" i would like to have "Bruce Willis", i created this extension to capitalized the first letter
extension String {
func capitalizingFirstLetter() -> String {
return prefix(1).uppercased() + dropFirst()
}
}
but it obviously capitalize only the first word in a string, so how i have to modify this extension to get the right result? ( i looked in the doc but i didn't understand very well )
String in swift4 has already a capitalized computed property on itself, so without implementing anything yourself, you can get the desired result using this:
self.namE.text = currentUser.displayName.capitalized
E.g.:
self.namE.text = "bruce willis".capitalized

include dictionary or array value in swift string with backslash notation [duplicate]
(2 answers)
Closed 8 years ago.
I create a dictionary, and I want to use println() to print dictionary content,
but it doesn't work, and I don't know how to solve it..
Please help... Thanks
var dictionary = ["name":"herny","age":20]
println("name = \(dictionary["name"])"); <--- this doesn't work, compile error because dictionary["name"] in \()
You can't put things with quotes in a \( ), you'll need to assign it to a variable:
var dictionary = ["name": "henry", "age": "20"];
let name = dictionary["name"];
println("name = \(name)");
